[Prior art] The present invention is an absorbent structure, such as a personal care product, which is more specifically an absorbent article having an absorbent body, which is composed of at least a part of a stable nonwoven absorbent structure. Absorbent articles are widely used in personal care products, such as diapers, children ’s toilet training pants ’adult incontinence clothing, medical clothing, sanitary napkins, etc., as well as surgical braids and sponges. These items can absorb and hold body waste, and are usually disposable and will be paid for after a limited period of use, which means that the recording will not be taken for cleaning or recovery_ reuse. Conventional disposable absorbent articles will include an absorbent body positioned between a liner that is in contact with the wearer's skin and an outer cover that prevents body exudates absorbed by the absorbent body from oozing out of the article. The liner of an absorbent article is generally liquid permeable to allow liquid excreta to pass through and be absorbed by the absorbent body. 'Separated fibers such as cellulose or other suitable absorbent fibers in general shaped fiber fabrics (usually referred to as air forming) used as absorbers for such absorbent articles are introduced into the air forming device together with particles or fiber superabsorbent materials in. Absorbing fibers and superabsorbent particles will flow in the air-forming process with the airflow, and will be directed to the porous forming surface. The mixed age of the absorbing and super-receiving particles will be left on the light-formed surface and absorbed by the shaft. Age fabric or structure. Air forming devices used in high-speed commercial operations usually have a forming surface composed of a boundary line screen or a scored grid, and—or more forming members. These forming members E: \ PATENT \ PK.001 〇8 \ 〇83l \ pk.〇〇l.〇83M doc2003 / 6/13. 200304794 and the boundary line mesh screen or fine grid usually define the length, width and thickness of the absorbent structure on the reduced surface. Pneumatic mechanisms, such as the hollow air suction system, attract air flow into the forming surface and allow the air flow to pass through the forming surface. Such systems have been applied to Tongyuan Business Records. By making this type of airborne transposition, Qingcheng's absorption structure has a basis weight (i.e., thickness) layer along its length and domain width direction, and also has a generally uneven width. When air-forming absorbent structures containing absorbent fibers and superabsorbent materials have proven to be very effective in manufacturing absorbent bodies of ideal heterogeneity and size for various absorbent articles, further improvements are also expected. More specifically, this type of structure lacks the integrity or stability of the absorbent structure that maintains its original shape (i.e., length, width, and especially thickness) after the wearer has repeatedly drained body fluids. For this purpose, it is known to use-traditional air-forming procedures to form-a stable absorbent fabric or structure to which a bonding material has been added. Such bonding materials have been coated or adhesives, powders, nets and bonding fibers. Bonding fibers already include—or more of the following types of fibers: homogeneous monofilaments, heat-fusible fibers, melt-blown polypropylene fibers, and so on. In the conventional air laying system, the connecting fiber system is mixed with the absorbent fiber and the superabsorbent material, and then the L system is used to attract the fibers to the forming surface, and this mixture is placed on the% surface of the pore. Then, the structure generated on the forming surface is heated to activate the connecting fibers, melting a part of the connecting fibers and forming an internal fiber connection with the absorbing fibers to produce a stable structure. However, such conventional air-laying systems are limited by the length of bonding fibers that can be effectively used. When operating conventional systems, the length of the bonding fibers is usually ό mm or less. If you use longer connecting fibers, it will lead to blockage of the sieve, uneven fiber distribution, fiber coagulation, and other inconsistent basis weights. Such air placement systems also require more energy. If the bonding fiber is heated to activate the stable fabric structure, it is necessary to extend the heating time of the structure excessively to sufficiently heat the bonding fiber. For example, a typical heating time via an air-linked system is 7 to 8 seconds. In addition, it is necessary to extend the cooling time of the fiber fabric excessively (such as winding storage in the warehouse), and to generate and save the ideal qualitative structure before the step-by-step processing operation. Therefore, the traditional air laying system is no longer suitable for manufacturing high-speed consumable product conversion machines. E: \ PATENT \ PK-001 08 \ 0831 \ pk-001-0831-l doc2003 / 6/13 6 200304794 . Rather, if a stable absorbent knot is desired to make an absorbent body of an absorbent article, the general method is to make a wider fabric than the required non-linear stabilizing fabric, and the fabric is wound and stored for individual use. Used in manufacturing machines. A particular disadvantage of such methods is that conventional air-laying systems are subject to hemp when sizing the dimensions of the stable structures they make. More specifically, the stable structure formed by the air-blocking system can have both a uniform width (such as a straight side edge) and a basis weight and thickness of a substantially uniform sentence. ^ Desired-like absorbent structure with inconsistent width. If it has an absorbent structure under the tree, it is necessary to unfold the previously prepared stable fabric and cut the fabric edge to provide the ideal width wheel. >#. Cutting and relying on the selected stable fabric sections in this way excessively wastes the amount of fabric and is too complicated in manufacturing operations. In addition, conventional systems require excessive costs for shipping, storage, and wrapping of lower density materials. In addition, if an inconsistent basis weight or thickness is desired so that the absorbent structure has a target area for increasing the basis weight to increase the absorption capacity, a smaller (narrower) layer must be cut from a stable fabric and compared to this Small layers of overlapping strands-larger stable fabrics to increase the basis weight of the absorbent structure on the target area. This requires additional steps and even complicates the manufacturing operation.

M. [Embodiment] Reference is now made to the drawings, especially to Fig. _, Which illustrates one according to the present document's overall command _ 21 wire. Tree-like waste from my sister. Some absorbent articles, such as disposable absorbent articles, are in use. Restricted discarding or recovery for reuse. However, the original invention of the county will be considered. It can be applied to outer cans, including reusable garments and other absorbent articles. For example, the principles of the present invention may be children's trousers and other baby and child watch products, medical outerwear, sanitary napkins and other female care products, and the like, as well as surgical straps and gauze. The diaper ⑼ in the figure-is unfolded and flattened to show one vertical axis X and-horizontal axis γ of the diaper. The diaper (21) usually comprises a central absorbent assembly (23), which passes from the front area (25) (i.e. the front) of the diaper through a lower area (27) (i.e. the central area) to the rear area of the diaper (i.e. the rear area) The central absorption assembly (23) is generally J-shaped, more specifically an hourglass, and has a display wheel gallery, laterally opposite side edges (31) and longitudinally opposite front and rear waist edges or ends, which are respectively (33 ) And I say no. It should be understood, however, that the diaper (21) may have other shapes, such as rectangular or tee-shaped, without departing from the scope of the present invention. The side edge (31) of the diaper (21) extends longitudinally from the front area (25) through the sub-condylar area (27) to the rear area (29) to form laterally separated leg openings (37) of the diaper when worn (p. Three images). For example, the area (25) usually includes 4 portions through the central absorbent assembly of the lower abdomen area of the wearer, and the rear area (29) usually includes the central absorption assembly portion through the lower rear area of the wearer. The lower crotch region (27) includes a portion passing from the crotch region (25) to the rear region (29) longitudinally through the wearer's crotch and interposed laterally between the wearer's legs. When worn on the wearer (picture 3), the diaper (M) further defines a central waist opening (413) and a leg opening (37). With particular reference to the second figure, the central absorbent assembly (23) of the diaper (21) includes an outer cover, generally indicated by (49), a bodyside liner (51) facing the outer cover, and an outer cover The absorbent body 'between the cover and the inside is represented by (53). The outer cover (49) of the illustrated embodiment E: \ PATENT \ PK-001 08 \ 0831 \ pk-001-083M doc2003 / 6/13 11 200304794 generally defines the length and width of the diaper. The absorbent body (53) has a width of _, which is less than the long-term production and the outer cover (49 degrees, so that the outer cover exceeds the ^ and end of the absorbent body in both vertical and horizontal directions. The body side (M) generally follows The outer cover is expanded together, or it may be desired to make it larger than (which would therefore define the length and / or width of the diaper) or smaller than the area of the outer cover. In other words, the bodyside liner (51) is ideally tied to The outer cover (49) is stacked but does not need to co-extend with the outer cover. M 4 In-Example t 'The outer cover (49) is stretchable and may or may not have a slight elasticity. More specifically, The outer cover (49) can be sufficiently extended so that once stretched below the weight of the absorbent body, "Miao Bu Cover" will not be substantially _ its original position [_. However, it should be taken into account that the Bu cover (49) can be Non-stretchable and still maintained within the scope of the present invention. The outer cover (49) can provide ideal stretchability as well as liquid and gas permeability for multilayer laminate structures. For example, the outer cover of the illustrated embodiment (49) is a two-layer structure, which includes an outer layer (55) made of a breathable material and an impervious layer The inner layer (57) made of liquid material, these two layers are connected by a suitable laminated adhesive (59). However, it should be understood that the outer cover (49) can also be constructed of a single layer of liquid-impermeable material, As will be mentioned later, the material used to construct the inner layer (5?) Is used to make a thin valve without deviating from the hair. The liquid-impermeable inner layer (57) of the outer cover (49) can be breathable (I.e., "breathable") or impermeable. The bodyside liner (51) is ideally compliant, soft, and does not cause irritation to the wearer's skin, and is used to help isolate the wearer's skin from the absorbent body ()). . The liner is less hydrophilic than the absorbent body (53) and allows the wearer to access a drier surface and has sufficient holes to allow liquid to pass through its thickness easily. A suitable bodyside liner (51) may be selected from a variety of mesh materials, but ideally is capable of being stretched in at least one direction (such as longitudinal or transverse). In a particular embodiment, the bodyside liner (51) is ideally stretchable and capable of extending along the outer cover to allow the diaper to fit the wearer. The fixing piece (65) (first and third pictures) is fixed on the central absorption assembly (23) located at the rear region (29), and extends from the opposite side edge (31) of the assembly forwardly. The fixing sheet (65) may be connected to the outer cover (49) 'body-side liner (51), between the outer cover and the liner, or other diaper (21) members. The fixing piece (65) may also be elastic or made of rubber. For example, the fixing sheet (65) may be an elastic material such as a neck-bonded laminate (NBL) or a stretch-bonded laminate (SBL).

Paper Corporation's IP SUFTO. A suitable non-woven fiber is i $ single fused 18453 fiber from Tencel Incorporated (located in Axis, Alabama, USA). The superabsorbent material used to form the absorbent structure (101) can be selected according to the chemical structure and physical form . These include superabsorbent materials with low adhesive strength, high adhesive strength, superabsorbent materials crosslinked on the surface, superabsorbent materials with uniform crosslinks, or superabsorbents with various crosslink strengths through the structure (101). Sexual material. Superabsorbent materials are based on chemical properties and include polyacrylic acid, poly (isobutylene-co-maleic anhydride), poly (ethylene oxide), carboxy-methylcellulose, and poly (vinyl tetrahydrogen) Ketones), and polyvinyl alcohol. Superabsorbent materials can expand from slow to fast. The superabsorbent material of the absorbent structure (101) of the present invention is ideally a particulate substance. However, the superabsorbent material may also be in the form of a foam, macroporous examples or microporous particles or fibers, microparticles or fibers having a fiber or microparticle coating or pattern. The length and diameter of the superabsorbent material can vary, and can also have various degrees of neutrality. The counterions are usually Li, Na, K, Ca.

An exemplary superabsorbent material is FAVOR® SXM 880, which is available from Stockhausen, Inc. (Greensboro, North Carolina, USA). Another exemplary superabsorbent material is available from Dow Chemical Company (Midland, Michigan, USA) under the name DRYTECH® 2035. One suitable fiber superabsorbent material is available from Camelot Technologies, Ltd. (located in High River, Alberta, Canada) under the trade name FIBERDRI® 1241. Another suitable superabsorbent material is available from Chemtall Inc. (located in RICEBORO, GA) under the brand name FLOSORB 60 LADY® and also LADYSORB ΕΛΡΑΤΕΝ1ΛΡΚ-001 08 \ 0831 \ pk-001-0831-l doc2003 / 6 / l3 γη 200304794 60®. Linkage Chengwei is ideally activatable ' e.g., When heated " to form an internal fiber linkage within the absorbent structure. The internal fiber links used herein may be between the linking fibers and the absorbent fibers, the linking fibers and the superabsorbent material, and / or the linking fibers between each other. In one embodiment, the connecting fibers are bi-component or multi-component connecting fibers. Multicomponent fibers as used herein are fibers formed from two (i.e., bicomponent) or more polymers that are extruded from individual extruders but combined to form a single fiber. The polymer is generally stably anchored in individual areas across the cross-section of the multicomponent fiber and continuously extends along at least a portion of the fiber, and more preferably extends along the entire fiber length. The structure of the multi-component fiber may be a sheath / core arrangement in which one polymer is surrounded by the other; a side-by-side arrangement; a pie skin-like array ' " island-like " arrangement or other suitable arrangement. Bicomponent fibers are disclosed in Kanek0 et al., U.S. Pat. No. 5,010,882, Krueger et al., U.S. Pat. No. 4,795,668, Marcher, et al., U.S. Pat. No. 5,540 " and Strack, et al. 5336552. Bicomponent fibers are also disclosed in U.S. Patent No. 5,382,400 issued by Pike et al., And the creases in the fibers can be generated by the difference in expansion and contraction rates of the two (or more) polymers. The multi-component linking fiber used herein means that at least one of the linking fiber components has a melting temperature that is lower than the melting temperature of at least one of the other linking fiber components. For example, the linking fiber may be a bicomponent fiber having a sheath-core arrangement in which the melting temperature of the sheath component is lower than the melting temperature of the core component. Once this bonding fiber is heated, the components with a lower melting temperature can be melted and combined with nearby absorbent fibers, superabsorbent materials or other bonding fibers, while the other components are usually left unmelted to maintain the integrity of the bonding fibers Sex. In other embodiments, the linking fibers may be monofilament or homofilament fibers, bicomponent fibers, etc., and mixtures of these fibers. The connecting fiber is ideally made of a material or a material that can be easily heated when exposed to excitation energy. In particular, the connecting fiber is ideally affected by non-conductive fibers due to exposure to electromagnetic energy. It melts to form internal fiber bonds in the absorbent structure. Non-conducting heating is a term used to generate electricity in non-conducting materials. This is a summary of cross-riding riding at a frequency of high ΕΛΡΑΤΕΝΤΛΡΚ-001 08 \ 0831 \ pk-001-0831-1 doc2003 / 6/13 18 200304794 Miscellaneous.

In addition to chemical transformation, L to Lian Zhiwei or other suitable linking materials, in addition to _ conductive heating to harvest or infrared plus thieves to activate other seams, as long as the link _ in the link to form a recording structure Before the inner fiber is connected, it is combined with the absorber (1 is called the joint seal., ..., and then Wei forms this e-knot, and then calls the natural absorbent structure). E: \ PATENT \ PK-001 08 \ 0831 \ pk-001-0831-1 doc2003 / 6/13 200304794 Ideally, the fiber length of the linking fiber is at least · lmm. Or, the linking fiber = at least 3%, or at least 6mm. In the step-featured embodiment , The length of the connecting fiber is 30 mm or more. Alternatively, the length of the connecting fiber may be as low as 25 mils, or as long as possible. Further, the absorbent structure (101) may include one of the sizes close to the absorbent structure. (E.g., long f or width).-Denier fiber activation, longer link fiber The length provides a greater number of internal fiber attachment points and helps improve the integrity and permeability of the absorbent structure i). Synthetic fibers suitable for use as connecting fibers in the absorbent structure (101) include synthetic matrix polymers (such as polymer Olefins, polyamines, polyacetone, polyetheramines, polyaminopotassium esters, polyesters, poly (meth) propionic acid And block copolymers, polyethylene glycol-b-polyethylene glycol block copolymers, polypropylene oxides such as polyethylene oxide copolymers, and combinations of these compounds) and any of those known in the art Suitable synthetic fibers. In one embodiment, an energy-containing additive can be added to the linking fiber during the production of the linking fiber, wherein the additive allows the linking fiber to reach the melting temperature quickly, much faster than the state without the additive. It allows the connection speed of the internal fibers in the absorption structure (101) to be faster than when no additives are added. Ideally, the additives can quickly absorb energy at the frequency of electromagnetic energy (that is, between 0.01 Ghz and 300 GHz). Like less than a second The time is ideally less than a quarter of a second, and most of it is half a second. However, it should be considered that the absorption structure related to energy absorption and the connection of the connecting fiber and the absorbing fiber within 30 seconds belongs to the present invention The melting range of the linking fiber will depend on many factors, such as power generation energy, additive acceptance, fiber denier, which is usually between 1 and 20, and the composition of the parent polymer of the linking fiber. Containing energy additives Tens can be added when the fiber's parent polymer is compounded, or the fiber can be coated and bonded after the fiber is produced. A typical method of combining additives with the parent fiber is to use a twin-screw extruder to let it meet these before extrusion ingredient. Once extruded, the mixed polymer is usually pelletized for easy storage and transportation. If the connecting fiber is a bicomponent fiber, the energy-containing additive can be added to the two fiber components or only one of them can be added. Energy-containing additives can also be added to the components of one or more bicomponent fibers, ideally continuous, and intermittently spread over the entire length and cross-section of the fiber. If the additive used is not compatible with the parent polymer to which it is added, a "compatibility agent" can be added to improve the mixing effect. Such compatibilizers are known in the art, examples can be found in US Patent No. 2003/794 issued by Gessner E: \ PATENT \ PK-OOl 08 \ 0831 \ pk-001-0831-1 doc2003 / 6 / l3 20 200304794 Found in No. 5108827. Containing energy additives can be accepted by a variety of specific spectrum of energy. Just like when a black object is exposed to solar energy, it will absorb more energy and become warmer than the same white object. The energy additive will absorb energy at its specific wavelength. Successful energy containment additives should have a non-conducting loss coefficient, which should be higher, as mentioned earlier. The non-conducting loss coefficient of the energy-containing additive used in the present invention is generally between 0.5 and 15 in chirp or microwave frequencies, and more specifically between 5 and 15. It should be noted that the non-conduction loss coefficient is unitless. Ideally, the non-conducting loss of the fiber is between 0 μm and 0.1%, more specifically between 0.3 and 0.7. For example, the energy-containing additives may be carbon black, magnetite, carbonized dreams, gasification dances, residual stones, earthen 'magnesium oxide, and titanium dioxide. The weight content of the energy additive can be between 2 and 40%, more specifically between 5 and 15%. The connecting fibers may be creped, expandable and / or elastic. Synthetic fibers combined with such energy-containing additives are described in U.S. Patent Application No. 10/034079, entitled "Targeted Bonding Fibers for Stabilized Absorbent Structures", filed December 20, 2001. There are more descriptions, the entire contents of which are incorporated herein by reference. An absorbent structure combined with a linking fiber containing energy additives is described in U.S. Patent Application No. 10 / 〇3386, filed on December 20, 2001, entitled "Target Linked Stable Absorptive Structure," (Targeted ON) -Line StabiKzed Absorbent Structures). In addition to having linking fibers that contain energy additives, there is another option. Linking fibers (or at least one component of a multi-component linking fiber) may have a lower melting temperature, such as below 200 C. It is more preferably less than 150β〇, more preferably less than ii ° C, more preferably less than 90C 'and most preferably less than 80 °. In this example, the absorbent fiber of the absorbent structure (ιοί) And superabsorbent materials can be used as a source of heat to indirectly transfer energy to melt the linking fibers with low melting temperature. Therefore, the absorbent fiber as an energy-containing material is excited to melt adjacent low melting temperatures in the linking fiber Polymer to bond with absorbent fibers, superabsorbent materials or each other. This melting will depend on many factors such as generator energy, moisture content, specific thermal energy , The density of the absorbent structure (101), the denier of the fiber (which is usually between 1 and 20), and the concentration and composition state of the low melting temperature polymer that binds the fiber.

E: \ PATENT \ PK-001 08'0831 \ pk-001-0831-1 doc2003 / 6 / l3 2 J 200304794 Low-melt / dish-linked fibers ideally have a low specific thermal energy to allow rapid heating and cooling of the absorbing structure ( 1G1). Low specific thermal energy is useful in thermal cycling, because the binding fibers are carefully absorbed during melting. Lai, low specific thermal energy is also useful during the cooling period of the absorption structure (view), because the heat is attributed from the company, making the company's job maintenance and stability. A suitable specific thermal energy range for the bonding fibers is 0.001 to 0.6 calories / gram. Ideally, the 'bonding fiber' also has a high thermal conductivity to allow rapid passage of thermal energy therethrough. Thermal conductivity is proportional to the density and thermal capacity / specific thermal capacity of the bonding fiber material. It is beneficial to use fibers with higher densities to achieve higher hot melt properties. For example, the ideal degree of binding fiber is more than 0.944 grams per square centimeter (g / cc). This is useful for accelerating the heating and cooling cycles during activation of the bonding fibers to stabilize the absorbent structure. It is preferable that the thermal conductivity of the bonding fiber is greater than 0.01 Joules / second-Mole-K. A material with a low melting point is also ideal as a bonding fiber. The low melting reduces the energy requirements, and allows the coupling axis to become a melted state, and then changes from a melted state back to a solid state during the cold section after fk. For example, the melting of the bonding fibers is ideally less than 100 Joules / gram, more specifically less than 75 Joules / gram, and more specifically less than 60 Joules / gram. Lian, '' cr ,, 'Dave ideally have a low melting viscosity after activation, i.e., once the fiber has changed from its solid state to a substantially melted state. In this way, the connecting fiber material can flow to the meeting point between the connecting fiber and the absorbent fiber, the superabsorbent material and / or other connecting fibers, so as to form a stable internal fiber connection. For example, the melting viscosity of the linking fibers is ideally less than 10,000 centipoise, more specifically less than 20,000 centipoise, and most specifically less than 10,000 centipoise. The connecting fiber ideally also has a proper surface energy, and can be wetted by the liquid absorbed by the absorption structure (101). This wettability is not required in all applications. However, if the linking fiber is not wettable in nature, wettability can be accomplished by various surfactants known to those skilled in the art. Suitable bonding fibers with low melting temperatures can be made from polyethylene-polyethylene based (pE_pvs) block or random copolymers, polyethylene_polyethylene oxide (PE_pE〇) block / joint copolymers, and polyethylene-polyethylene oxidation (PP_PE0) block / junction copolymer, polyester, polyacetate, polyamine, polypropionate, polyamidopotassium (ester or ester based). The melting point can be adjusted by va or H: \ PATEN-nPK-OOJ 08O83I \ pk-〇〇l.〇83M doc2003 / 6/13 22 200304794 PE〇 (because these polymers have VA and PEO) or structure Adjustment. Bonding fiber materials can be made by mixing them in a twin extruder, Sigma mixer or other mixing equipment, and then using conventional nonwoven processes such as meltblown and spunbond to make the fibers. For example, the absorption structure incorporating such low melting temperature associative fibers is described in U.S. Patent Application Serial Number ⑽⑽ Milk, filed on December 20, 2002, with the title "Absorbent Structures Having Low Melting Fibers", The entire contents of which are incorporated herein by reference. Other polymers and sensitizers can also (or alternatively) be used with energy-containing additives in the manufacture of bonded fibers. Specially selected and / or placed groups along the polymer chain Can affect the non-conductivity loss coefficient of polymers and increase the polymer's reactivity to electromagnetic energy. These include polymer composites consisting of mixed, bulk, bonded, copolymers, ionic polymers and copolymers, and metal salts Ideally, the presence of one or more groups along the polymer chain causes the following phenomena: (1) increased bipolar moment of the polymer; (2) increased unbalanced electron valence of the molecular structure of the polymer. The groups include, but are not limited to, acetaldehyde, ester, carboxylic acid, sulfonamide, and thiocyanide groups. The selected group may be covalently bonded or ionically linked. Attached to the polymer chain. As mentioned above, groups containing functional groups with high bipolar moment are ideally along the polymer chain. Suitable groups include, but are not limited to, urea, stone wind, amines, Nitric acid, nitrite, isocyanate, alcohol, ethylene glycol, and ketone groups. Other suitable groups include groups containing ionic groups, including (but not limited to) steel, zeolites, and bell ions. For example The nitric acid group can be connected to the aromatic hydroxyl group in the polymerization chain. It should be noted that the nitric acid group can be connected between the aromatic technical groups or the pair of positions. Further, it should be noted that other groups can be connected to the nitrate group. The aromatic light group in the group is in the position of a few or two. Suitable groups include (but are not limited to) the nitrite group. In addition to these modifications, other monomers can be incorporated into the polymer It further improves the reactivity of the final polymer. For example, monomers containing urea and / or amine groups can be incorporated into the polymer. Suitable groups include acetaldehyde, carboxylate, and thiocyanate groups However, others have or can improve molecular structure Electron valence can also be used; or groups with ionic or conductive groups (such as sodium, zinc, and potassium ions) can also be used. Other ionic or conductive groups can also be used. 〇 土 ΕΛΡΑΤΕΝΤ \ ΡΚ-001 〇8 \ 〇831 ^ -〇〇1.〇831-1 doc2003 / 6/13 23 200304794 Specific combinations include low density PE / polyethylene-polyvinyl acetate block copolymer, LDPE / polyethylene glycol, PE / Polyacrylate, polyethylene-vinyl acetate copolymer, polyacetate, polypotassium urethane, polypropionate, polyethylene glycol (PEG), polyamidamine (PAA), polyethyleneimine (PEEM), polyvinyl acetate (PVAC), polyvinyl alcohol (PVA), polyformic acid-sodium salt (PMA-Na), polyacid sodium salt (PA-Na), and poly (styrene Sarcoic acid-co-methyl alcohol acid) sodium salt (P (SS-co-MA) -Na), and polymers of terephthalic acid, and 1,4-butanediol, and polybutene succinate Copolymer. Other materials include terephthalic acid polymer, adipic acid, and 1,4-butanediol, which are sold by BASF under the trade name ECOFLEX®, or Eastman Chemical Co. are also sold under the trade name Eastar BioTM Copolyester. Mixing and joining copolymers of the above polymers are also suitable. The absorbent structure (101) of the present invention is ideally a single structure. The single structure of the absorbent structure (101) used herein means that the absorbent structure is a single non-woven fabric or a mixed layer product containing multiple absorbent fibers, connecting fibers or superabsorbent materials. In the illustrated embodiments of the first to fourth figures, the 'single absorbent structure (101) generally includes the entire absorbent body (53) of the diaper (21) (i.e., the size of the absorbent structure substantially defines the size of the absorbent body). However, it is considered that the absorbent body (53) may include one or more layers, wherein at least one of these layers is the absorbent structure (101) of the present invention, and it is within the scope of the present invention as long as the absorbent structure itself is a single structure. For example, in one embodiment, the absorbent structure (101) is formed by first forming or collecting absorbent fibers, superabsorbent materials, and connecting fibers, so that they can be activated before the connecting fibers (i.e., the inner fiber connections in the absorbent structure). (Before) forming a single structure with a desired shape, profile and / or material distribution to form a nonwoven, substantially pre-stable, absorbent structure. Subsequently, the linking fibers are activated to form inner fiber links in the absorbent structure, thereby stabilizing the absorbent structure. Alternatively, an essentially hydrophilic sheet (not shown) may be used to maintain the integrity of the absorbent structure (101) or absorbent body (53). Thin wraps are usually placed on an absorbent structure or absorbent body to cover at least the two major surfaces of the two, and the thin wrap is composed of an absorbent fibrous material (such as a creped plug) or a wet-strength sheet. Miscellaneous sheets can also be used to provide a capillary layer which allows the liquid to be quickly distributed into the absorbent fibers in the absorbent body (53). The wrapper material on one side of the absorbent body can be joined to the wrapper on the opposite side of the fiber mass to effectively wrap the absorbent body. In the example, the pre-stabilized absorption structure (101) (i.e., before the activation of the linking fibers) E. \ PATENT \ PK-〇〇i 〇8 \ 083l \ pk-〇〇1.0831-1 doc2003 / 6 / The material composition of 13 24 200304794 can be G.1 to 60% by weight connection fiber, Q to _ weight ratio absorbent material, and 5 to 98% by weight absorbent fiber. More specific examples can be 2 to 1 molar ratio of Li, Weiwei,% super absorbent material to the weight of the dove and%, absorbent age to 70% by weight. In its readings, the county hybrid structure can have 0.1 to 5% by weight of linking fibers. In another embodiment, the pre-stabilized absorbent structure ii) may include a certain amount of linkage 'which is at least αm% of the total weight of the absorbent structure. Alternatively, the amount of linking fibers is at least 30% or more. . In other aspects, the maximum content of the linking fibers may be a weight ratio of °, or more. Alternatively, the amount of bonding fibers may be up to 20%, or may be up to 5% by weight. The absorbent fiber, the connecting fiber and the superabsorbent material are ideally distributed in the absorbent structure, approximately passing the entire width of the absorbent structure, and along the level and thickness of the absorbent structure. However; and the concentration of the absorbent, fiber, linking fiber and / or superabsorbent material in the structure (101) may be uneven thickness or zeta direction (I27). For example, higher concentrations of absorbent fibers, linking fibers, and / or superabsorbent materials can be placed in different tissue layers (i.e., the zeta direction) or in different regions (i.e., along the length or through the width) of the absorbent structure. It is also considered that the-or more tissue layers or regions of the absorbent structure (101) may not have connecting fibers and / or superabsorbent materials, as long as the absorbent structure is an integral structure and at least in the structure; 2 sections may contain connecting fibers . Adjunct fibers composed of different materials can be placed in different tissue layers or regions of the absorbent structure (101) without departing from the scope of the present invention. The average basis weight of the pre-stabilized absorbent material (101) is 25,000 homework / square meter (gsm), more preferably between 50 and 2000 gSm, and even more preferably between 100 and Yuan Qingzhi. between. It may also have an uneven basis weight along the width or length of the pre-stabilized absorbent structure (101), which may have one or a higher basis weight 11 domain, and—or a lower basis weight region. In at least a high basis weight region, a specific portion of the absorbent structure may have a constituent basis weight, which is at least · gsm. Alternatively, the 'he basis weight region may have a basis weight of 75 gsm, or it may have a basis weight of at least 800 #m. In other aspects, the high basis weight region of the absorbent structure (101) may have a composition basis weight of 2500 gms or more. Alternatively, the basis weight of the high basis weight region may be less than or equal to 2000 gsm, and more specifically less than or equal to 1500 gSm. E: \ PATENT \ PK-001 08'0831 \ pk-001-0831-1 doc2003 / 6 / l3 25 200304794 In addition, in at least a low basis weight region, the pre-stabilized absorbent structure (101) may have Composition basis weight of at least 50 gSm. Alternatively, the basis weight of the low basis weight region is at least 100 gsm, or at least 150 gsm. In another alternative construction, the low basis weight region of the absorbent structure (101) has a composition basis weight of 700 gsm or more. Alternatively, the basis weight in the low basis weight region can be as high as 600 gsm, or as high as 500 gsin. In another aspect of the present invention, the absorbent structure (101) formed before the activation of the linking fibers may have a density of at least 0.01 g / kg measured at a limiting pressure of 1.38 KPa (0.2 psi). cc. Alternatively, the degree may be at least 0.02 g / cc, or at least ⑽3. In other respects, this density can be as high as ai2g / cc or more. Alternatively, the density may be as high as 0.1 g / cx, or as high as 0.1 g / cc. In one embodiment, the entire pre-stabilized absorbent structure is substantially uniform. In another embodiment, the density is uneven over and / or along the length of the absorbent structure. The "unequal sentence" used in this case is about a specific property or feature of the absorption structure, and is used to indicate that this character or feature is undefined in the absorption structure, or depends on the irregular sentence structure. The variation, that is, the non-uniformity of observation, is greater than the non-uniformity of regular manufacturing and the tolerance variable that must be generated in the process of manufacturing the absorbent structure. The non-uniformity can be expressed in the form of a gentle gradient or a gradient of P, as the concentration, the base and / or the density suddenly changes from a tissue layer or region to a tissue layer or region in the absorption process, and It can occur repeatedly in an absorbent structure or be confined to specific areas of the absorbent structure. The pre-stabilized absorbent structure may also have a thickness that is not the same along the length of the absorbent structure and / or in the direction through which the absorbency ends. This thickness is the distance between the major surfaces of the absorbent structure, and is based on the vertical distance from the point _ in the z-direction of the absorbent structure to its major surface. The change in thickness can be a gradual change in gradient, or a step-like change, so that the thickness can be changed from one part of the absorbent structure to the adjacent part. So one or more parts of the 'absorptive structure ii) may have less thickness, while other trees of the absorptive structure may be «her wealth. For example, Lai Shishi towels, professional diapers, (absorptive structure (101) part of the absorbent structure (2) and (4)) are generally thicker than other components of the absorbent structure, and are roughly the same as the front area of the spread (25) Correspondence increases the absorption capacity of the target area.

As shown in the second figure, the Xingliu Yan part (103) is also located at the center position between the side edges (105) of the absorbent structure and is laterally separated from the side edges. , Ϋ́ σ In addition, or alternatively, the pre-stabilized absorption structure (101) may have an inconsistent width along the length of the absorption structure. This width is the series of absorbing knots_edges, and is determined by the direction parallel to the Υ axis of the absorbing knot =. The width change can be expressed in the form of a gradual or gradient change, or a step change: where the width suddenly changes from part of the absorbent structure to part. For example, the absorbent structure (101) can have many shapes, including a rectangular shape, a J-shaped coin shape, and an ideal upper or lower area (27) than the front or rear area (25, 37) t of the diaper pi. As shown in the first figure, the shape of the absorbent body (53) is defined by the absorbent structure (101), and is generally τ-shaped, where the word "τ" = the ribs roughly correspond to the front of the diaper (21) To improve the effect, especially for male infants. However, it should be understood that the pre-stabilized absorbent structure (101) may have a thickness that is substantially uniform and 7 or-read on the balance, God, "Lai_, _5) is generally straight and in The absorption structures are parallel to each other in the longitudinal direction.

The unshaped during and after activation of the linking fibers used herein means that the shape and foot position of the linking fibers are not treated within the absorbent structure, specifically In other words, the longitudinal ends, side edges, and main surfaces of the absorbent structure can be changed when the connecting fibers are heated to a substantially melted or activated state when pressure is applied to the connecting fibers. For example, in a typical molding operation, the connecting fibers During or after heating, at least one or both major surfaces of the absorbent structure or the absorbent structure are compressed against or within a mold, or the mold itself is heated to heat the bonding fibers. Such molding procedures force the absorbent structure to reposition -Orientation is generally involuntary, and can also be embossed on the main surface of the absorbent structure.

In determining the strength of the stable absorbent structure (101), any pre-formed and individually provided reinforcing members should not be measured together.

Approximately equivalent equipment is also available. The liquid permeability of the absorbent structure (101) will also be affected by the binding of the binding fibers to stabilize the liquid permeability of the absorbent structure. Darcy's Law is used to define the absorption saturation of a specific amount of liquid. More specifically, liquid permeability here refers to properties defined by the following liquid permeability tests. Liquid Permeability Test A suitable liquid permeability test equipment is shown in Figures 15 and 16. The test equipment includes a drum (1134) and a piston ' roughly as shown in (1136). The piston (1136) includes a cylindrical LEXAN shaft (1138) 'which has a concentric cylindrical hole (1140) passing downward through the longitudinal axis of the shaft. The shaft (1138) is treated at both ends to provide ends (1142, 1146). A weight, as shown in (1148), is placed on the end (1142) and has a cylindrical hole (1148a) passing through at least a portion of its center. A circular piston head (1150) is placed on the other end (1146) and has a concentric inner ring formed by seven holes (160) (each hole diameter is 0.95 cm), and the outer one Concentric outer ring formed by 14 holes (each with a diameter of 0.95 cm). The holes (1154, 1160) pass from the top of the piston head (1150) to the bottom. The piston head (U50) also has a cylindrical hole (1162) passing through its center to engage the end (1146) of the shaft (1138). The bottom of the piston head (1150) can also be covered with a biaxial pull E: \ PATENT \ PK-001 08 \ 0831 \ pk-001-0831-1 doc2003 / 6 / l3 29 200304794 stainless steel mesh screen (ll64).

Chicago, Illinois, u.s A has an office. A stainless steel cloth mesh screen (1166) is connected to the bottom end of the barrel (1134), which can be tensioned by a double shaft before connection. The mesh screen (1166) has a square mesh with a mesh size of 105 micrometers. The representative material for this screen is McMaster-Carr Supply part number 85385T976, which is available in Chicago,

Illmois ^ U.S.A. Has an office. A composite material () is supported on a mesh screen (脳). The barrel (1134) is either passed through a transparent LEXAN rod or its equivalent, or is pierced through a LEXAN tube or its equivalent, and the inner diameter of the barrel is 6.00 and the height is 10 cm. . The drum includes a set of drainage holes (not shown) or other elements suitable for maintaining the liquid in the drum to maintain the south degree on the U,, and sieve (1166) to 7.8 em. The piston head (115Q) is mechanically treated with a [EχΑΝ rod or equivalent, so that it is southward and has the size of the smallest side wall gap and can slide freely just inside the barrel (1134). The hole (h62) in the center of the live II, (1150) is used to mate with the shaft end (ι146) and connect with the shaft end (11, tightly and impermeablely. Shaft ⑴38) is treated with a LEXAN rod or equivalent Its direct control is 2.32 cm and its inner diameter is 0.64 cm. Tip ⑴46) Length 2 54 cm and diameter ^ 52 cm, forming a ring-shaped shoulder to support the heavy weight ⑴ 仙). The inner diameter of the ring weight (⑽) is M9, which allows it to slide onto the haiku at the end of the shaft (II38) and stop on the ring-shaped shoulder formed by the shaft. Ring weights are made of stainless steel or other materials that are resistant to osmotic pressure salt solution. The weight of the piston (1136) and the weight (1M8) is about g, and the corresponding pressure is 28.27 cm2. There are 20.7 dynes in the area. As the solution flows through the piston / ® barrel equipment, the shut-off (lm) usually stops at _ 16 mesh hard stainless steel lion red (paste). Alternatively, the reading combination can be called on a matching support ring (not shown) on the wall of the barrel, but it will not effectively restrict the flow from the bottom of the cylinder. Living base and weight quilt; in a _g drum to measure the size of the bottom of the weight to the top of the guan. This measurement is measured using the caliper of the smallest unit. Alternatively, it can also be measured using a volume measuring instrument with an accuracy of 0.01 leg, such as Mitutoyo America Corporation's Model IDF 1050E measuring instrument, which has an office in Urora, the heart of the heart, and USSA. The result of this test 1 (later will be used to calculate the height of the rubber bed. Measure the sentiment of each _ bucket empty and continue to chase knees E: \ PATENT \ PK-001 08 \ 0831 \ pk-001-0831-l doc2003 / 6 / 13 30 200304794 It is important to use that piston and weight. When the absorbent tube expands, the same piston and weight should be used for measurement. The sample of the absorbent structure used to determine the liquid permeability is obtained by placing a circle Shaped sample (such as a cut sample) is placed in a G.9% (W / V) Naa liquid spreader (the sample should be in contact with a screen) for 60 minutes to form a swell to a diameter of 6011111. At this time, the saline can be placed in a plate. Use a rough plastic or rubber with a uniform opening and a mesh of about 2-15 mm to allow the saline to contact the liquid-permeable cup to expand the sample. When the 60 minutes are approaching, place the piston And the weight is placed on the expanded sample in the barrel, and then the barrel 'piston', the saline and the sample are completely removed from the saline. The thickness of the expanded sample is measured using a micrometer to measure the bottom of the weight to the barrel. The size of the top is determined. Alternatively, the measurement can be performed using a volume measuring instrument with an accuracy of 0.001 _ Measurements, such as Model IDF-1050E measurement instrument from Mitutoyo Ameriea Corporation, which has A to A in Aurora, Illinois, us A. The zero point of the initial thickness test is constant. Let The thickness obtained after expansion of the absorbent structure 値 subtracts the thickness 测量 obtained from measuring empty drums, pistons, and weights. Finally, 値 is the height "H" of the expanded sample. The liquid permeability measurement of the absorbent structure is obtained by adding NaQ solution to Started with a barrel (1134) with an expanded sample (1168) 'piston (1150)' and a weight (1148) inside. 09% NaC1 was added so that the height of the saline solution on the bottom of the expanded absorption structure sample was 7.8 cm. Measure the amount of liquid passing through the expanded sample according to time and weight. Once the liquid is highly stable and maintained at 7.8 cm, collect data every second for 3G seconds. The flow rate Q of the expanded sample (Satoshi) is in gm / sec is the unit, which is measured by the liquid through the smallest square of the sample (1168) (g) in unit time (seconds). The liquid permeability in square micrometers is obtained by the following formula: K = [QxHxMux 108] / [AxRh〇xP] where κ = liquid Permeability (square micrometer), (^ = flow rate (g / sec), H = height of the expansion absorption structure j (cm), Mu = liquid viscosity (poise), cross-sectional area of liquid flow (cm2), density of liquid (g / em3), and the static pressure of Pi body (up to gjW). The static pressure of collision is calculated by: P = Rh〇xgxh E: \ PATENT \ PK-001 08 \ 0831 \ pk-00l-083l-l doc2 〇〇3 / 6 / l3 31 200304794 where Rho = liquid density (g / cm3), g = acceleration of gravity 'usually 981 cm / sec2' and h = liquid height, as mentioned in the liquid permeability test equipment mentioned above 7.8 cm. Generally, the higher the liquid permeability of the absorbent structure at saturation, the more open the structure will be. Therefore, the absorbent structure can absorb the extra liquid more easily and is less likely to leak liquid. Without a bonding material, the liquid permeability of the nonwoven absorbent structure is based only on the characteristics of the superabsorbent material and the absorbent fibers, so the liquid permeability will be lower, such as less than 20 square microns. The integrity of the absorbent structure (101), more specifically the void volume, can be increased by stabilizing the structure with a linking material, and more specifically, multi-component linking fibers to sufficiently increase the liquid permeability of the absorbent structure. For example, after the activation of the linking fibers, the liquid permeability measured by the absorbent structure of the stable absorbent structure (101) through the liquid permeability test described above is ideally greater than 20 square microns, and more preferably greater than 40 square microns. More preferably, it is larger than 60 square microns. It should be understood that the liquid permeability may be non-uniform along at least one of the width and length of the absorbent structure (101), as long as the liquid permeability of the absorbent structure itself is at least greater than 20 square microns. Without wishing to be limited by theory, one should also believe that too high a concentration of linking fibers in a stable absorbent structure will negatively affect the liquid permeability of the absorbent structure. In order to help increase the liquid permeability of the absorbent structure, the concentration of the linking fibers in the absorbent structure is desirably between 0.1% and 10%, and more preferably between 0.1% and 5%. increase. By forming the absorbent structure (101) in a substantially final form prior to activation of the linking fibers, i.e. having a desired length " width " thickness and / or basis weight, no additional shaping, i.e. cutting, is required. Therefore, even if the width of the absorbent structure is non-uniform, the side edges of the absorbent structure (101) remain in a cut state after the connecting fibers are activated. It is also considered that the longitudinal ends of the absorbent structure (101) may not be cut, as each absorbent structure is directly formed into a separate form, rather than a continuous fabric which is then cut into separate structures. The side edges of the prior art stability absorbent structure must be cut to an ideal width profile, usually with a profiled edge profile, or surface profile, which is roughly concave as shown in Figure 10_. I do not want to be limited by Special Theory to believe that the concave surface profile is formed by the fibrous material on the side edge because the absorbent structure is privately pressed when its side edge is cut. Conversely, for the stability absorbing structure (10) of the present invention, the cut wji ideally has a _ cross-section edge profile * surface wheel, such as approximately straight and ideally convex, rather than concave. For example, stable One of the absorbent structures ⑽) is cutting H: \ PATENT \ PK-001 08 \ 083l \ pk-001-0831-I doc2003 / 6 / l3 32 200304794 The profile of the side edge of the side edge is shown in the twelfth figure, where The surface contours of the side edges are convex. The thirteenth and fourteenth figures illustrate the difference in fiber positioning between the uncut side edge of the absorbent structure (101) and the cut side edge of the prior art absorbent structure, respectively. As shown in the thirteenth figure, there is no certainty that the absorbent structure (ιι) locates the fiber on the cutting edge over the entire surface profile. The positioning of the fibers on the cutting edge of the prior art absorbing structure is split, especially on the inner segment of the surface contour, so it is considered involuntary along the entire surface contour. One-edge skin lightening test, and one experiment to quantify the side and edge sections of the traditional stable absorption structure (where the side edge has been cut to form an ideal width profile) and the stable absorption structure formed according to the present invention ( 101) is the difference between the cross-sectional profiles of the cut sides. The five samples in the first group corresponded to the traditional stable absorbent structure in which the side edges were cut. Each test sample had a basis weight of 350 且 and a thickness of 0.25 忖 (about 8 mm), and 0.5 忖 (about 12 mm) from the side edge of the absorbent structure. Five samples of the second group _ 于 本 发 _ Stable absorption structure, which is more ship-like. Corresponds to the absorption structure shown in the tenth figure (Simplified), which has a central region with increasing thickness and eases the longitudinal end of the absorption structure. And following. These test samples have a basis weight of 35G gsm and a thickness of q 25 inches (8 mm), and 0.5 inches (about 12 mm) from the side of the absorbent structure. Each test sample was placed on a flat, black, thin piece of paper of size Mg and illuminated with a herringbone ring-shaped light source to provide incident omnidirectional illumination. Samples and background tissue paper are arranged vertically under the lens of a suitable image analysis system (e.g., Cambridge / Ldca, located in Bannockbum, Minois, USA, with a trade name such as _gift-Jen). , So that the sample covers half of the surveillance system (right half). Image formation was performed using a 50mm EL-Nikkor lens, f / 2 g, with this _to-F and F-to-C adapters, available from Nikon OEM Sales (in Melville, New York) . The working distance between the two samples is 25G mm (about 10 inches). _The total area of the pixel The size (ie length) is 57 mm (approximately 2.25 inches). Use the software program in Annex 1 to fix the optical brightness on the edge of the paste. More specifically, the light intensity reflected by the 60 WW frame shed is used, and the width of each frame is 0.59 mm. The arrangement of Fang Wu is for some structures (such as the μ 3 spray reaction of the black structured tissue paper from the sample side edge outward, while the remaining structures reflect the straight extension from the sample inward and are approximately flat with the sample XY E: \ PATENT \ PK-001 08 \ 083l \ pk-001-0831-1 doc2003 / 6/13 33 200304794 The side edge of the sample is vertical. The measured brightness is based on a 6-point grayscale, where 0 grayscale units are equal to black, and The 64 gray scale units are white. The white level is set at 0.75 volts, so that the approximate maximum brightness in a frame is between 90 and 96 ° / the maximum gray scale. A "transition" brightness corresponds to the scanning structure. The outermost side of the group is defined as a non-zero brightness reading in the scanning architecture. Beginning with the architecture defined as transitional brightness, it is depicted according to the logarithmic distance of each architecture from the initial architecture inward and including the initial architecture. The brightness readings obtained from the next u architectures (traveling inward from the side edge) are used (for example, using the Excel software of Micr0sft). Then, the data is converted into a second-order polynomial function of the curve to determine 2 in the function. And X's coefficient "b", its deletion-_Xie Ji minus ten analysis Obtained 95% confidence range. Tested on both sides of each sample. For the _set of samples corresponding to the traditional stable absorption structure where the side edges were cut, the brightness data is used to convert the brightness data into two parts of the curve. The coefficient "a" of the χ2 term in the first order polynomial function is _1779 to -28.81, and the median is -23.30. On the contrary, the coefficient 'V' corresponding to the stable absorption structure sample with uncut side edges of the present invention ranges from 6 · 37 to 1103, the median is please. In the first set of samples, the coefficient "b" of the χ term of the two and more polynomial functions used to convert the luminance data into a curve is between 45 · 90 and 53 · 7. 〇, t number is 49.80, and the second group of coefficients "b," is between 21 · 71 to 26.69, with a median of 24.20.

By slicing the upper layer into a more ideal width, the 'absorption n' has a width layer in the width direction. However, in the present invention, the absorption structure (1G1) forms a mono-structure, so that the exhaustion level in the width direction of the absorption structure is substantially less than that of the traditional resolution level.

The image forming system uses a -20 face-on lens (f / 4, with F to c adapter) to complete, such as Nikon OEM Sales' from Mdvme, n γ, u § a, which has a variety of connected neutral density converters (such as alternating and polar), The intensity of the light reaching the scanner is controlled. Working distance between lens and test sample Cut to mm (approximately 18 inches). The total field size of 900 pixels is 253 mm (approximately 10 inches). Optical brightness patterns below the sample length (for example, sample samples not blocked by black construction tissue, Including the area with increased thickness) is determined using the software program in Annex 2. The sample is based on the corresponding absorption structure _ axis direction of the sample. __ The sample. However, the sample should also be tested according to the horizontal axis direction of the absorption structure. The light green brightness of the sample was measured on the 60 frame below the sample money, where the width of each frame is 3 mm. The measured brightness is based on a 6-point gray scale, where the 0-order unit is equal to black and the 6-error unit is White. The brightness level under the sample length (that is, the change in the thickness of the sample) is determined by multiplying the frame measurement 値 by U (that is, an increase of 10%). If the phase E: \ PATENT \ PK-001 08 \ 0831 \ pk -001-0831-1 doc2003 / 6 / I3 35 200304794 If the measured data of the neighboring architecture exceeds this threshold, the hierarchy will be jealous. The brightness hierarchy at each sample length (which is traditionally used by students as n = 4 or 3) Analyzed by Lin Lin and Gu Laixi, the sentiments of Eding are closed according to the tradition. For the compilation (on the upper-frequency filament of the needle), the average gradeless range is between 4.02 and 6.84 gray scale units s / mm, of which the number is M gray scale units s / mm. On the contrary, it is 'stabilized according to the invention' A sample of a sexually absorbing structure (with an integrated structure, the gray scale of the sweat average shell degree ranges from ㈣ to 2.31 gray scale units s / mm, and the needle impurity 162 gray material level _. Therefore, ideally, the average brightness level of the stable absorption structure of the present invention (001) has a non-uniform thickness in the width direction, and is ideally a G 5 to 3 Q grayscale unit—and, more logically, 0. .93 to 2.31 gray scale units s / mm, as determined by the absorption structure brightness test. At locations where the thickness is uneven along the length of the suction structure, the average π-degree stratum in the middle of the longitudinal ends in the money direction is also in the range of 0.5 to 3.0 gray scale units s / mm (by the Absorption Structure Brightness Test Institute). Measuring foot), I ideal is 0.93 to 2.31 gray scale unit s / mm. At the position where the activated fiber is activated by non-conductive heating (for example, exposed to the electromagnetic quantity) by the pre-stabilized absorption structure, the stable absorption structure also has Unique physical properties produced by electromagnetic energy activation. These characteristics can be used for qualitative and quantitative measurement of the degree and position of oxidation, as well as the efficiency of attachment within the absorbent structure. More specifically, techniques such as external lines, visible light, near-infrared, infrared, and Raman spectroscopy; surface analysis; differential scanning colorimetry, chromatographic separation; and various microscopy techniques can be proven by alignment / heart, or infrared The radiant heat transfer and "external" heating are unique properties of materials produced by "inner-shao heating" using non-conductive technology. By infrared and convective heating, radiant energy is converted into heat on the surface of the absorbing structure where the temperature rises rapidly. The thermal energy on the outer surface of the absorbent structure will eventually diffuse toward the center of the absorbent structure through heat conduction. This heating process is slow and requires more time to bring the center of the absorbent structure to a critical temperature that can melt the connecting fibers in the center of the structure. The slow process is based on the thermal conductivity of the structure and its overall size (such as thickness). Therefore, in this type of heating process, the oxidation of the fiber is directed towards the outer surface of the structure (or more specifically On the external surface). The thermal connection in this way will also create some on the external surface of the absorbent structure Into yellow fibers. "E: \ PATENT \ PK-001 08 \ 083l \ pk-001-0831-1 doc2003 / 6/13 36 200304794 For non-conductive heating (that is, using electromagnetic energy), the absorption structure (101 ) The highest temperature is also near the surface of Wai Shao. However, the temperature rising in the center of the absorption structure ii) is almost equal to the temperature of the external surface. This is because the Lai reduction process is active and straightforward. This chick is connected to the absorption junction, and the central energy transmission is less affected by thermal conductivity, but rather by the non-conducting 11¾ and non-conducting range length of the absorbing material. In other words, the heating effect usually occurs from the center of the absorption structure (dish) toward the external surface. Infrared energy must be applied 3 to 30 times longer than non-conductive heating to allow the entire absorption structure to heat up. More specifically, f needs to be extended so much to obtain the ideal temperature critical value (such as the melting temperature of the connecting fiber) in the center of the structure. When properly implemented, the ' non-conductive heating effect occurs quickly and is relatively uniform. Fast and uniform direct heating prevents substantial thermal degradation of the polymer in the heated absorbent structure. The percentage of oxidation that occurs in any particular structure is directly proportional to the time that the polymer is exposed to elevated temperatures (such as 75 ° C). Infrared heating is more effective than microwave heating to maintain a relatively constant surface temperature throughout the heating cycle. Infrared and conduction The percentage of oxidation generated on the outer silk surface of the absorbing structure is 5 to 6% (or more) greater than the percentage of non-conductive heating on the external surface of the structure. Therefore, the absorbing structure is heated by microwave radiation A structure will be produced, the oxidation of this structure on its external surface will be 5 times less than its center, and more specifically 3 times less. The difference in oxidative degradation is due to the fact that the surface heating is more than the solution used previously. The analytical techniques described above are used to measure. In this application, typical compounds produced by oxidative degradation include high-color substances (highly polar absorptive, some color compounds are produced by presaturation in the sense. Examples include polymeric unsaturation Carbon compounds, unsaturated ketones, organic chain-containing carbonyls, Xi Kun, and having nearly free form, exclude reaction, and The oxidation / degradation mechanism of the break of the Italian chain forms a compound of a conjugated double bond, ','. Generally, the increased oxidation can be easily found with the naked eye, which makes materials using infrared and convection heating look yellow, so it will Poor quality. A fast 'non-destructive method for analyzing compounds produced by thermal degradation on polyolefins and cellulosic materials is described here. UV and visible spectra are measured on a controlled and heated sample. The final spectrum is Subtracted and compared with the spectra of a series of reference samples (made by heating a series of comparative samples at a higher temperature to support heating during different periods known).

This basic program can use UV and visible fluorescence, neutron spectra, and infrared spectra. Secondary to provide similar and complementary results. For more subtle structural analysis, polymers and cellulosic materials can be dissolved in appropriate solvents, processed by liquid chromatography, and using the above-mentioned spectroscopy techniques or a large number of spectra to Further analysis to determine the structure and molecular weight of any degrading compound. These compounds usually have high chroma, such as yellow or brown, due to the brown effect of thermal degradation oxidation. There are many literatures describing synthetic and natural polymers Detailed analysis of degradation compounds, and most of the techniques are sufficient to measure the relative oxidation of the entire cross-section of the heated structure. In addition, the use of scanning electron microscopes with iron tetroxide consumables can show the integrity of the internal bond junctions. Indicate the maximum heating temperature at which any part of the heating structure is reached during the procedure. Figures 5 through 10 illustrate an embodiment of the equipment, designated by (⑵), for the manufacture of a stable absorption according to the present invention and the method described above.

The device (121) has a specified length or length, a device direction (I23), a specified width or length across the machine direction or a machine cross direction (η5), and a paper thickness or z direction. For the purposes of this disclosure, the machine direction (123) is the direction in which a particular component or material is conveyed longitudinally, or along and through a particular, original location of the device. The machine transverse direction (125) is roughly on the plane where the material is conveyed and passes through the program, and is perpendicular to the original machine direction (123).

Drum cymbal) is mounted on a shaft (139) connected to an object (143) by a bearing (M1) (seventh figure). As shown in the second diagram, the drum wall-the ring wall (145) connected to the shaft (39) rotates in connection therewith. The shaft (139) is driven by a suitable motor or linear shaft (not shown) to rotate counterclockwise, as shown in the fifth and sixth figures. The ring wall (145) has a cantilevered surface (135) and the opposite sides of the drum (137) are married. An air guide E: \ PATENT \ PK-00l 08 \ 0831 \ pk-001-0831 I doc2003 / 6/13 38 200304794 tube_ 'is extended through the inside of the drum on the forming surface (135). The rotator has an arched, elongated inlet (149) on the porous forming surface (described later in more detail), allowing liquid to circulate between the shaped surfaces. The air duct (47) is in communication with the air supply duct connected to the air source (153) (schematically shown in Figure 7). For example, 眞 can be a suction fan. The hollow air duct (147) is connected to the hollow air supply duct _ along the outer surface of the duct, and extends in accordance with the closing of the duct. Hollow duct ceramic_Supply frame 1M) projects radially toward the forming surface (135), and includes laterally spaced (147α) and angled spaced end walls (147B). The shaft shaft extends through the wall (145) and enters the air supply duct (151), and is connected to the two bearings (I55) inside the duct. The bearing (155) is sealed by the empty supply duct (1S1) so that air enters the duct

The rear 'air around the shaft (I39) cannot be sucked. The stent (57) and the entire catheter are supported by an upper stent (159). A factory drum frame (161) (seventh picture) is installed on the wall (丨 45) of drum cymbal 7) and the drum frame ⑽) has a hole in its surface, allowing fluid to pass through the thickness of the drum frame completely freely Move like ^ qi. The drum frame (161) is generally tubular and extends around the axis of rotation of the shaft ⑴ 9) and near the niche). The drum frame (161) is suspended from the drum wall (145) and has a radially inwardly facing surface adjacent to the entrance (H9) of the 眞 it duct (导管 7). In order to provide an air-resistant seal between the frame (1δ1) and the inlet (149) of the hollow duct (丨 47), a drum frame seal (163) was installed on the inward facing surface of the drum frame (161) for sliding , And sealed with the wall (M7A) of the hollow catheter. A cover (not shown) is also installed on the end wall (147B) of the hollow catheter (1) for sliding, and is sealedly engaged with the inwardly facing surface of the drum frame (161). The closure can be made of a suitable material that allows sliding, sealing engagement. Looking back at the sixth figure, the device (m) further includes a forming chamber (^), and the forming surface (135) can contact the rotating drum (137) and move through the forming chamber (171). More specifically, in the illustrated embodiment, the forming surface (135) moves counterclockwise in the forming chamber (171), which is roughly from an entrance (173) (the forming surface passes through this entrance (Π3 ) Into the forming chamber that does not contain fiber lining in nature) to an exit (Π5) (the forming surface will leave the forming chamber through this exit (〖75)), and the pre-stabilized absorption structure (101) is formed in the forming chamber ). Alternatively, the drum (137) may be rotated clockwise relative to the forming chamber (Π1). The forming chamber (17 丨) is supported by an appropriate supporting frame (not shown as a gradual support, if necessary or desired, this supporting frame can be tied to and / or connected to other suitable doc2003 / 6 / i3 E: \ PATENT \ PlC-001 08 \ 0831 \ ρ | ς · 00 U〇831 · j 39 200304794 on the component. Substitute the two 彳, wear tree material 'like cotton wool (177) (fifth and sixth picture) shape ^ The absorbent fiber is conveyed from a waste raw material (not shown) to a fiberizing machine (179), which can be a traditional rotary hammer, a filling rotary cotton roller or other suitable fiberizing device. Fibrosis The machine (197) 7) separates into individual, loose absorbent fibers, and allows these fiber edges to shape to (Π1) inside. In the illustrated embodiment, the fiberizing machine ⑽) is located in the forming room (⑺), and it should be understood that the fiberizing machine (M) can also be located away from the forming room (⑺), and absorb, cut, It is possible that other suitable devices can be used to transport the cisform ridge in other ways, and still belong to the scope of the present invention. The fibers or particles of the superabsorbent material can be transferred to the forming chamber (⑺) by using transmission structures such as pipes, channels, spreaders, nozzles, etc. and a combination of these items. In the illustrated embodiment, the ' superabsorbent material is fed into a forming chamber (171) via a delivery conduit (181) and a nozzle system (not shown). The connecting fiber material is sent from a suitable connecting fiber supply source (183) (in the form of a bale) to a suitable opening device (185) to roughly separate the connecting fibers into individual, loose connecting fibers. . For example, the opening device (185) can be used for picking, carding, planing, etc., and a combination of these actions. Then, the selected amount of connected fiber is directed to a metering device (18), and the metering device supplies a controlled amount of the connected fiber to a connected fiber delivery catheter (189). For example, the connected fiber meter 1 ^ (187) may This is a type 5 Tiger CAM-1X12 device, which is available from Fiber Controls, Inc., and has an office in Gastonia, North Carolina, USA. A bellows (191) or other suitable device can be used to help connect the fibers through The delivery catheter (189). In the illustrated embodiment, the connecting fiber catheter sends the connecting fiber into the fiberizing machine (171) so that it can be homogeneously mixed with the absorption fiber, and then the homogeneous mixture of the absorption and connection fiber is sent. Into the forming chamber (171). However, it should be understood that the connecting fibers can also be sent to the interior of the forming chamber separately from the absorbent fibers, and are located at a point other than the transfer point where the absorbent fibers are sent to the forming chamber by the fiberizing machine (179). If the position where the connecting fibers are fed into the forming chamber (Π1) is closer to the forming inlet (173), the connecting fibers will be concentrated on the main surface of the absorbent structure (101) formed on the forming surface (135), or Forming surface (193) or inside. If the connecting fiber is sent to the forming chamber (171), which is closer to the exit of the forming chamber E: \ PATENT \ PK-001 08 \ 0831 \ pk-001-0831-l doc2003 / 6/13 200304794 (175 ) Position, the connecting fibers will be more concentrated on the main surface of the absorbent structure (101), or on the free surface side (195) (sixth figure) or outside. Alternatively, the connecting fibers may be combined or incorporated with the source of the absorbent fibers. Among them, it is not necessary to enter the air forming device (131) separately from the absorbent fiber. For example, the connecting fiber may be mixed with the absorbent fiber before the absorbent fiber is sent to a supply roller (ie, cotton wool (177)). (135) In the illustrated embodiment, it is defined by a series of shaping elements, or forming members (201), and the forming members _) are arranged end-to-end around the forming drum 7), and are separately connected to the drum. As shown in the eighth figure, the forming members (201) each define a substantially identical pattern for collecting the fibrous material. These figures correspond to the ideal length, width, and thickness of a body absorbent structure (0011), and the individual absorbent structure (101) will be repeatedly wound around the periphery of the drum. However, some repetitive or non-repetitive decorative shapes can be mixed with money, and should also be leftover-continuous, non-patterned absorbent structure can be formed on the forming surface (CD), for example, the forming surface is flat, ^ The shaped absorbent structure is usually rectangular and then processed into the desired shape (for example, by cutting other methods). ° < Referring to the eighth to tenth drawings, the forming member _) includes a porous member (205), which is operable and also {is fixed on eight branches (135). The forming member (205) may include a coarse mesh screen, a variable mesh screen, a cable fabric, a perforated member, etc., and a combination of these elements. In the embodiment shown in the tenth figure, several channels (209) are formed by making grooves, which are approximately radial L extension X allows two gases or other selected gases to be removed from the drum (137) The outer surface moves freely towards the inside of the drum. The channel (209) can have any desired cross-sectional shape, such as a circle, an oval, a hexagon, a pentagon. α With particular reference to the tenth figure, the outermost surface defined by the porous member ㈤5) in the radial direction may be equipped with a surface profile of an uneven sentence depth (that is, the ζ direction (127)) to the forming surface (135) The pre-stabilized absorption structure (1G1) formed on it provides-ideal unevenness. In an ideal arrangement, the change in the surface profile z direction may have -selected_, and the pattern society may be regular or unclear. For example, the surface profile can be designed to provide the selected pattern along the circumference of the forming drum. Surface, the surface contour of the porous structure (205) of the JTL figure 10 thus defines the longitudinally opposite end regions ^ having a first average depth; and-the central region having-greater than the first average depth, the second average depth. Each of the end regions with the _ average and depth can be aligned on the forming surface H) H: \ PATENT \ PK-001 08 \ 0831 \ pk-001-0831-1 doc2003 / 6/13 41 200304794 Shape j Absorption structure ( 101) A region and / or thickness with a lower basis weight is provided, while a center with a larger second average depth may provide the absorbent structure with a higher basis weight and / or thickness. Rationale: Each of the regions with a first-average depth can be substantially adjacent to the adjacent region with a larger second depth. The porous member (can be designed to have a Z-profile of the surface profile through the profile surface width In order to provide a basis for the weight and / or thickness of the uneven sentence through its width, the absorption on the yelling surface should be provided. In the heart row, the surface contour of the pore member (205) defines a substantially trapezoidal shape. Alternatively, 'rounds can be defined-hemispherical or flat. In the illustrated embodiment, the depth profile defined by the porous member (205) forms a pocket area ㈣, which extends along the forming surface 的-Shao Ludu according to the machine direction ⑽), and passes through the width of the financial center portion To form the absorption structure shown in the fourth figure. * Further, one or more non-flowing areas of the forming surface can be selected by using a suitable blocking mechanism (not silk-formed or closed or flowing money through the forming surface ⑴5). Therefore, the blocking structure can offset or reduce the amount of fibers in the area covered by the forming surface (135) with the blocking texture. The clutter mechanism can optionally be set to form other ideals f of the absorbent structure (1G1), such as forming a series of nicks (not shown) on the formed absorbent structure. For example, the female can read the _ induction point, so that it will be able to help find the position and place it after the absorption and time of the _㈣ side that is vertically connected to the absorption on the forming surface (I35) (1Q1). . Still > Considering the eighth to tenth drawings, the forming member (2〇1) may also include one or more side decorative members (= 3) 'Sometimes also referred to as a contour ring for the absorbent structure (ι〇ι) Provide an ideal shape (ie width wheel ^). For example, in the illustrated embodiment, the side decorative member (213) is made of a pair of laterally opposed 5 clothing members, which can be laterally surrounded with each other around the forming drum (the closing of each member.) Along the length thereof, there are —unevenness — side ridges, so that the laterally opposite side wall of the side-mounting rider ㈣ defines an absorbent structure _) width wheel ^ on the forming surface ⑽). More specifically, the inner side wall (215) of the side decorative member ㈣ has a secret profile in the machine direction (123). Therefore, the side decorative member can provide the forming member ⑽) a wide area for replacement. Therefore, from the air-forming device (called the absorption structure of the output Luohe has a width profile 'It is uneven at least _ part of the length along the structure. E: \ PATENT \ PK-001 08 \ 0831 \ pk-001- 0831-1 doc2003 / 6 / l3 42 200304794 In another aspect, at least one of the side decorative members (213) may have one or more main flaps (not shown). For example, individual main flaps may be used to Manufacture or confirm the circumference of the forming drum (137): the length of each intended absorbent structure (101). When an air forming device is used to produce a disposable absorbent structure (such as a diaper, child training pants, female care products, adult incontinence products, etc. Etc.) This type of side decoration member (213) is particularly advantageous. It should be understood that the inner side wall (215) of the side decoration member (213) may also be linear (i.e., parallel to the machine direction (213)) to provide A generally rectangular, band-shaped absorbent structure (101). It should also be understood that the side edges (105) of the absorbent structure (101) can also be cut and removed, cut and folded, and the methods of these methods. The combination is provided, and the forming surface (135) is used here as a part of the forming drum (137). At the same time as the examples, it is also understood that other techniques for providing a forming surface can also be used to deviate from the scope of the present invention. For example, the forming surface (135) may be formed by an endless forming belt (not shown). Such forming belts are shown U.S. Patent No. 5,466,409, entitled "Forming Belts for Three-Dimensional Space Forming Applications," (f〇RMINC} BELT FOR THREE-DIMENSIONAL FORMING APPLICATIONS), which was published on November 14, 1995. In the manufacture of a formed ' In the operation of the nonwoven pre-stabilized absorbent structure, that is, before the connecting fibers are activated to form the inner fiber connection in the absorbent structure, the hollow source (153) (seventh figure) will generate in the hollow tube (147) relative to the forming chamber ( 171) internal emptiness. When the forming surface (135) enters and then passes through the forming chamber (171) toward the exit (175) of the forming chamber, the absorbent fibers, connecting fibers and superabsorbent materials in the forming chamber are effectively carried or conveyed by an air-carrying airflow And attracted inwardly by the hollow space facing the porous forming surface. It should be understood that absorbent fibers, superabsorbent materials, and bonding fibers can also be borrowed from any suitable fluid in the forming chamber (171). It should be understood that any gas system used as a transport medium is a general reference here, which includes any fluid that has a transport effect. The air passes inwardly through the forming surface (135) and then through the air supply duct (151 ) And leave the drum (137). Absorbing fibers, bonding fibers and superabsorbent materials are collected by the forming member (201) to form a pre-stabilized absorbent structure (101). It should be understood that the intensity or degree of hollow suction effect may be It is selectively adjusted to control the density of the absorbent structure (101) formed on the forming surface (135). Higher suction intensity can result in a higher density or low porosity absorbent structure (101), while lower suction intensity can result in a lower density or higher porosity E: \ PATENT \ PK-001 〇8 \ 0831 \ pk.〇〇, .〇83doc2003 / 6/13 43 200304794 absorption structure. The specific degree of suction intensity will depend on the specific flow characteristics of the forming chamber (171). Obviously, the known short and repeated trial and error method can be used to find the ideal pumping strength. The density of the absorbent structure (101) before activation of the linking fibers is important for controlling the desired functional properties of the subsequently stabilized absorbent structure. Thereafter, the drum (137) carrying the absorbent structure (101) leaves the forming chamber (171) through the opening (175) to the cutting system (271) (as shown in the fifth and sixth figures), where the absorbent structure has more thickness than Can be trimmed and removed to a predetermined level. The cutting system (271) includes a cutting room (273) and a cutting roller (275) in the cutting room. The cutting roller (275) grinds away excess fibrous material from the absorbent structure (101), and the removed material is conveyed away from the cutting chamber (273) by a suitable drainage duct known in the art. For example, if desired, the removed fibrous material can be recycled back to the forming chamber (m) or the fiberizing machine (179). In addition, the cutting rollers (275) can be rearranged and redistributed along the absorbent structure (machine direction (123) and / or machine direction (125) of the 101). The rotatable cutting rollers (275) can It is operatively connected and combined with a shaft member (not shown) shown, and is driven by a suitable drive system (not shown). The drive system may include any conventional equipment, such as a special motor, or a coupling, gear Or other transmission, which is operatively connected to a motor or drive mechanism using a non-rotating forming drum (137). The cutting system (271) can provide a traditional men's tailor mechanism to remove or redistribute the formed surface ( 135) the excess thickness of the absorbent structure (101). The cutting operation can cause the absorbent structure to contact the cutting roller (2), and produce-on the main surface (that is, the free surface side ( 193)) has an absorbing structure (ιοί) with the desired profile. For example, the cutting roller (275) can be designed to provide a substantially flat surface along the cutting surface of the absorbing structure (101), or alternatively Designed to provide an uneven surface. (275) is adjacent to the forming surface (135), and the forming surface is conveyed through the cutting roller when the drum rotates. The cutting roller (275) of the illustrated embodiment rotates clockwise to the drum ( 137) rotates in the opposite direction. Alternatively, the cutting roller (275) can also rotate in the same direction as the forming surface (135) on the forming drum (137). In either case, the cutting roller (275) should be appropriately selected To provide effective cutting effect on the contact surface of the formed absorbent structure (101). In a similar way, any other suitable cutting mechanism can be used instead of the cutting system (271) to Provides cutting of the fiber absorbent structure (1G1) by relative movement between the absorbent structure and the selected cutting mechanism E: \ PATENT \ PK-001 08 \ 0831 \ pk-001-0831-l doc2003 / 6/13 44 200304794 Cutting or abrasion effect. After the cutting operation, the forming surface portion forming the absorbent structure (101) is moved to the release area of the device (121) outside the forming chamber (171). In the release area, the absorbent structure (101 ) Will be sucked from the forming surface (135) onto a transport device ⑽ ^ as shown in the fifth and sixth figures. This release can be assisted by using the air pressure inside the drum (137). The transport device (281) receives the formed absorption structure (101) of the forming drum (137) and transports the absorption structure to a collection area or a location for further Processing (not shown). For example, suitable transportation devices may include conveyor belts, air drums, transfer rollers, electromagnetic suspension transportation devices, fluid suspension transportation devices, etc., and combinations of these devices. In the illustrated embodiment, The transportation device (281) includes an endless conveyor belt (283) which surrounds a roller (285). An empty suction box (287) is positioned under the conveyor belt (283) to suck the absorbent structure (101) off the forming surface. The conveyor belt is porous, and the empty box (287) forms a full state at the position of the conveyor belt near the forming surface, so that the empty state in the empty box can act on the absorbing structure (101) on the forming surface (135). . The removal of the absorbent structure (101) from the forming surface (135) is also accomplished by the weight of the absorbent structure, centrifugal force, mechanical injection, positive pressure, or a combination of these methods, or other suitable methods' without departing from the present invention. range. For example, in the illustrated embodiment, the absorption structures (101) leaving the forming chamber are connected end-to-end to form a fabric or a series of absorption structures. Each absorption structure has a selected shape and is approximately the same as The corresponding shaped members (201) used to form each individual absorbing member correspond. Referring now to the fifth figure, when the pre-stabilized absorbent structure (101) is transferred from the forming surface (135) to the transport device (281), each absorbent structure is then conveyed to an activation system (304), where the fibers are connected Activated to the inner fiber bonds within the absorbent structure. In one embodiment, the linkage activation system (304) includes an activation chamber (306) through which each absorption structure (101) passes, and a generator (308) to activate the absorption structure through each. In the chamber, the radiation activates the electromagnetic energy in the chamber. For example, a suitable microwave generator can provide a sufficient amount of microwave energy and direct this energy through a suitable waveguide (310) to the activation chamber (306). In an embodiment, the electromagnetic energy may be RF energy with a radio frequency (PP) of at least 0.3 megahertz (MHz). Alternatively, the frequency is at least 300 MHz and optionally at least 850,000 MPIz. In other aspects, the maximum chirp of this frequency may be 30,000 MHz, or more. Alternatively, this frequency can be up to 30,000 MHz, or optionally up to 2600 MHz. In a specific embodiment, the wireless E: \ PATENT \ PK-001 08 \ 0831 \ pk-001 0831-1 doc20〇3 / 6/13 45 200304794 is ideally 27 MHz. In another implementation, the electrical intercept can be microwave energy, which ranges from 915 MHz to 2450 MHz. '' In a particular setting, electromagnetic energy can selectively heat the bonding fibers above their melting point. The melted linking fibers can then be viscous or linked and selectively connected to absorbent fibers, superabsorbent materials and / or other linking fibers within the absorbent structure. The linking fibers can also be substantially activated without heating the entire absorbent structure (101). In a particular aspect, the linking fibers can be activated quickly, but can avoid excessive heating of the absorbent structure (101). Heating and thawing the binding fibers in the activated absorbent structure (101) can be achieved by any available effective mechanism. For example, electromagnetic energy can heat water vapor present in the absorption structure (101), and heated steam can selectively melt the connecting fibers. In another mechanism, electromagnetic energy can be absorbed by the linking fibers' and the absorbed energy can selectively heat and melt the linking fibers. The total residence time of the absorbent structure (101) in the activation chamber (306) can provide a unique efficient activation period. In a specific aspect, the activation period is at least 0.02 seconds. Alternatively, the activation period may be at least 0.05 seconds, and may also be at least 0.001 seconds. In other aspects, the activation period can be up to 3 seconds. Alternatively, the activation period can be 2 seconds or 1.5 seconds. The activation chamber (304) may be a conditioned space in which electromagnetic energy can generate an effective and continuous wave. In a particular aspect, the activation chamber (304) can be designed as a resonance chamber. A suitable device for a resonance activation chamber system is disclosed in U.S. Patent No. 5,536,921, issued by Hedrick et al. On July 16, 1996, a system for providing microwave energy to sheet materials, (system FORAPPLYING MICROWAVE ENERGY IN SHEET-LIKE MATERIAL); and Bmndon et al.

After heating the bonding fibers, exit the activation chamber (304). The absorption structure (101) can also be cooled or treated. A cooling system can be used to cool the absorption structure (Lai). This cooling system includes ·· 冷 漆 气 Ε: \ ΡΑΤ ΕΝΊΛΡΚ-00 | 08 \ 083l \ pk-001-0831-l doc2003 / 6 / I3 46 200304794 Body's cold 2 gas, radiation cooling, air cooling, ambient air cooling, etc., and a combination of these methods. As shown, the cooling system may include a refrigerated gas supply hood (321), an air transport device (323), a bellows (325), and a freezer or other freezing element (327). A freezing element (327) may be provided A suitable coolant to a heat exchanger (329), and the bellows can circulate air through the heat parent for cooling. The cooled air can be directed to the supply hood (321) and to the absorption structure (101). Then, the air is led out of the supply cover (321) to circulate through the heat exchanger (329) again. In a particular aspect, the absorption structure (丨 〇1) can be cooled to a set temperature, which is lower than the bonding fiber material Melting temperature. On the other hand, the absorption structure (101) can be cooled to a temperature not exceeding 200 ° within a selected downward flow setting distance of the activation chamber (304). In further On the other hand, the absorption structure (101) within the selected set distance can be cooled to not exceed 15 degrees of compliance. Therefore, after the absorption structure (101) is exposed to the high-frequency electromagnetic energy of the activation chamber (304), the set distance can be measured. In a specific aspect, the set distance can have a minimum of 0.5 m value. Alternatively, the set distance may be at least 0.75 m, or at least 丨 m. On the other hand, the maximum value of the divergence can be 30 m. Alternatively, the set distance may not exceed 20 m, and may not exceed ι〇㈤. On the other hand, the increased portion of the heated absorption structure (101) can be cooled to a set desired temperature within a specific time. The time can be determined from the time when the increasing part of the activation structure leaves the activation chamber. Therefore, the set time can be measured after the absorption structure is exposed to the high-frequency electromagnetic energy in the force of the silk chamber. In particular, the set time The minimum value of is _ seconds. Alternatively, the full time can be set to at least 0.075 seconds or at least 0 seconds.
