Description

(2) Feiyue of the invention should be described. The technical field, prior art, content, embodiments, and drawings of the invention are briefly described. [Technical field to which the invention belongs] The present invention relates to a fibrous structure containing particles Fibrous materials, disposable diapers, adult incontinence diarrhea, sanitary napkins and the like. More particularly, the present invention is directed to a fibrous object having a very high particle load, particularly particles of a superabsorbent polymer. C ^ »γ -ϋ.】 BACKGROUND OF THE INVENTION Absorbing objects (such as disposable diapers, adult incontinence diarrhea, sanitary cotton, sanitary diapers, and the like) usually provide an absorbent core for receiving party and retaining body fluids. The absorbent core is usually sandwiched between a liquid-permeable top sheet (which functions to allow liquid to pass through to the core) and a liquid-impermeable back sheet (which functions to contain liquid and prevent it from reaching the wearer through the absorbent object) Clothing of people who absorb objects). Absorbent cores for diapers and adult incontinence pads often include a fibrous batting or mesh fabric composed of defibrillated, loose, short-fibrillated, hydrophilic cellulose fibers. The core may also include a layer or stratum (often referred to as a storage layer or a thin layer) comprising superabsorbent polymer (SAP) particles, fine particles, flakes, or fibers. In recent years, the demand for increasingly thinner and more comfortable absorbent objects has increased. This object can reduce the thickness of the core of the diaper, increase the amount of SAp particles by reducing the amount of fibrous material used in the core, and reduce the Kal (caliper) by rolling or pressing the core (thus increasing the density 583001 (invention degree).

This higher-density core will not absorb liquid as quickly as a lower-density core because a tight core (compacting) will produce a smaller effective pore size. Therefore, in order to maintain proper liquid absorbency, it is necessary to provide a lower density layer having a size of 5 pores larger than that of the high-density absorbent core to increase the liquid absorption rate discharged onto the absorbent body. The low density layer is typically referred to as an acquisition layer. The multilayer absorptive core design involves more complex manufacturing processes. The storage layer portion of the disposable diaper can usually be suitably formed from loose, short-fibrillated cellulose, for example, during the conversion process. This cellulosic material is usually not available in the form of a pre-formed roller, 'because it does not have sufficient strength of the mesh fabric (due to its lack of adhesion or entanglement between fibers), it cannot be directly wound up and handled in an absorbent pad manufacturing facility . 15 Ultra-thin feminine tampons are usually made from non-woven

Material manufacturing. This pre-formed absorbent core material roll can be unwound directly onto the absorbent object conversion equipment without the defibrillation steps required for staple-based products such as diapers and incontinence pads. The non-woven mesh fabric is typically bonded or consolidated during the conversion process in a manner that provides sufficient processing strength of 20 degrees. These mesh fabrics may also contain SAP particles. In pre-formed cores made in the form of drum-like products, the mesh fabric reinforcement mechanism used provides strength and dimensional stability to the mesh fabric. This mechanism includes latex bonding, bonding with thermoplastic or bicomponent fibers or thermoplastic powders, hydroentanglement, needling, carding 7 5830011, description of invention or similar methods. However, at high particle loads, the core structure has poor particle loading. In other words, some particles tend to leak from the structure during manufacturing, handling, shipping and conversion, and during use. This can result in dirty manufacturing and conversion equipment and negative consumer perceptions of the product. For the absorption core material, what is needed is to make it easy to transport the liquid from the collection area to the storage area, and it has good particle loadability under high particle load. It can be used even at high particle load. It also provides high pull-down performance, which is thin but has high absorption capacity when in use, and it can be transported in the form of a roller-shaped quotient to simplify the manufacturing and conversion process. Published PCT application WO 00/71790 discloses an absorbent object comprising a layer of functional particles, which are selectively provided in some lanes, wherein the side edges of the object are free of functional particles It can be sealed to contain the loose particles in the structure. 15 The object of the present invention is to provide a fibrous mesh fabric which contains a functional particle in a large amount and can form an absorbent object. Another object of the present invention is to provide a method for manufacturing a fibrous mesh fabric, which comprises a functional particle existing at a high load and can form an absorbent object. zo Another object of the present invention is to provide an improved fibrous material containing a high load of functional particles and having high flexibility.

C Embodiment 3 Detailed Description of the Invention All patents and patent applications cited in this patent specification are hereby incorporated by reference into this patent specification. If there is any inconsistency in terms, this announcement shall prevail. The present invention relates to a layered fibrous mesh fabric comprising a plurality of thin layers of functional particles. Each thin layer of functional particles contains a channel or region of functional particles' and each channel or region is connected to a ® channel bite region 12 583001 玖, description of the invention. The functional particle layer of Elian has been oriented so that when the mesh fabric is viewed in the z direction, the functional particle lines or areas of the functional particle layer of one layer are not thinner than the functional particles adjacent to the next layer. Layers of the official moon b-shaped particle lines or areas directly overlap or overprint together. In other words, the lines or regions of the first thin layer of functional particles are complementary to the lines or regions of the next adjacent thin layer of functional particles. Reference is made to Figure 1, which shows a top view of a thin layer of functional particles. In a preferred embodiment, the structure of the present invention can be made using air-down technology. For reference purposes, these figures show the structure of the invention 10 extending in the MD or machine direction (also referred to as the γ direction). The cD or cross direction is perpendicular to the MD. Finally, the z-direction refers to the thickness of the structure and is orthogonal to the X-Y plane. The thin layer 2 in FIG. 1 includes a plurality of lines 6 and 8 extending longitudinally in the Y direction. Each lane contains functional particles. The edge 2 of the thin layer 2 is free of functional 15 particles. The space 14 between each lane is also free of functional particles. The thin layer 2 may be laid on another thin layer of functional particles or on another thin layer not containing functional particles. Referring to Fig. 2, there is shown a second thin layer 4 of functional particles. This thin layer also contains longitudinally extending functional particle channels. However, the lanes are configured so that when the thin layer 2 is laid on the thin layer 4, the lanes will not be overprinted together when viewed from the 20 z direction. Similarly, the tracks of the thin layer 2 will not be superimposed on the tracks of the thin layer 4, even when an intervening thin layer containing no functional particles is disposed between the thin layers 2 and 4. The spaces 14 between the tracks in the thin layers 2 and 4 are preferably substantially free of functional particles, fibers or any other material. Non-functional materials, such as fibers, can optionally be provided between these 13 lanes and the description of the invention. During the manufacturing process, before the fibers are properly fixed by fiber hardening, a small portion of the particles will drift from the lanes to the spaces without side effects. Reference is made to Figure 3, which shows a cross-section of a multilayer structure according to the present invention (taken from the x direction), which contains several thin layers of functional particles. The first thin layer 16 does not contain functional particles, and preferably contains a matrix substrate and provides an adhesive. A thin layer 4 is provided above the thin layer 16 and contains the channels 12 of functional particles between the channel-free spaces 14 of particles or fibers. The "thin layer" is provided above the thin layer 4. The thin layer 2 is then disposed above the thin layer 18 so that the tracks 6 and 8 of the thin layer 10 do not overlap with the tracks of the thin layer 4. Again, the comparison Preferably, there are no particles or fibers in the interval 14 of the thin layer 2. The thin layer 20 is provided above the thin layer 2. The other thin layer 4 is disposed above the thin layer 20 so that the line 12 is not superimposed on the thin layer 20. On line 6 or 8 of layer 2. Finally, a thin layer is provided on top of thin layer 4. Each of thin layers 18, 20, and 22 does not contain functional particles, and b contains the same or different types and amounts of The fibers act as either layers or each other. The resulting multilayer structure includes a thin layer of alternating fibers and functional particles, so that the lines of these functional particles are substantially surrounded by the fibers. Side edges of the multilayer structure of Figure 3 Optionally, an edge loose seal can be provided, as described in PCT application WO00 / 7179〇 (this announcement is hereby incorporated herein by reference). The description of the multilayer structure in Figure 3 is for clarity There are three thin layers of functional particles. However, the structure may contain as few as two thin layers, or may Many thin layers suitable for special applications. In a preferred embodiment, six layers of this thin layer can be provided. 14 583001 (ii) Description of the invention The multilayer structure of Figure 3 itself can include other in a single multilayer structure Thin layer to provide, for example, a structure with specific liquid acquisition, distribution, and storage capabilities. Line 5 The line of the thin layer of functional particles shown in Figures I-3 is parallel to the MD or Y direction of the thin layer and Continuously extending. However, the lanes or areas (hereinafter collectively referred to as "lanes") may be arranged in other ways suitable for the present invention. For example, the lanes may be kept in parallel, but may be provided periodically The particles are provided with line segments with gaps between the segments, as shown in FIG. 7 in Fig. 7. Furthermore, the lines can be laid in an s shape in the longitudinal direction, and the lines have an S shape between the lines. The intervals are shown in Figure 4. Furthermore, the lines can be hourglass shaped, as shown in Figure 5. Similarly, other patterns such as circles (Figure 6) can be used. However, it is important Yes per functional particle / thin layer included Both the lines with g particles and the spaces 15 without functional particles must be arranged so that the lines or areas of the thin layer of the first functional particle will not be overprinted on the second next Tian Bilian's thin layer of channels or areas above the functional particles. Notwithstanding the foregoing, a small percentage (less than 15%) of the area of channels or areas overprinted on each other is also considered to meet this definition. Provided by the functional particles The preferred coverage of the thin layer of functional particles is 20 depending on the application and thickness, density and other parameters of the particles. It is generally preferred that the line of the thin layer covers at least 30% of the thin layer (preferably It is 40% and preferably 50%) of the XY area. Functional particles This functional particle line is intended to accept particles, flakes, powders, fine particles 15 583001 玖, invention description or the like. The particles may include any particles having a particle diameter of up to 3,000 microns (e.g. pulverized meal or other particles. The particle region may include particles containing 2 to 2,000 gsm (grams per square meter)). The amount is more preferably 2 to 1, more preferably 5 to more preferably 10 to 600, and most preferably 100 to 250 gsm. These particles may be superabsorbent polymers ("SAp,") or other Functional materials. Other suitable particles include odor control agents (for example, fossil or calcium carbonate), perfumes, detergents, and the like. Superabsorbent polymers are water-soluble compounds that have been crosslinked 10 to make it insoluble in water, but it can still swell to at least about 15 times its own weight in physiological saline solution. These superabsorbent materials are usually classified into a special grade, in other words, are grafted with palace powder. Copolymers, cross-linked methylcellulose derivatives, and modified hydrophilic polyacrylates. Examples of absorbent polymers include hydrolyzed starch-acrylonitrile graft co-polymers, 15 saponified propylene Fumarate-Ethylene Copolymer, Modified Crosslinked Polyvinyl alcohol, neutralized crosslinked polyacrylic acid, crosslinked polyacrylate, and carboxylated cellulose. Preferred superabsorbent materials will form hydrogels after absorbing fluids. The superabsorption The bulk polymer material has a relatively high gel volume and a relatively high gel strength (as measured by the shear modulus of the hydrogel). This preferred material also contains a relatively low degree of polymeric material (It can be extracted by contact with synthetic urine.) Superabsorbent polymers are quite well known and commercially available. One example is under the designation IM 100 (Horst Cyranes (Hoechst-Celanese), Portsmouth, VA) 16 583001 玖, starch grafted polyacrylate hydrogel sold as described in the invention description. Other commercially available superabsorbent polymers are Trademarks Sanwet (Sanyo Kasei Kogyo Kabushiki, Japan), Sumika Gel and SA60S (Sumito Card Plus Cool Card) Sumitomo Kagaku Kabushiki Haishi (Japanese) Favor (Stockhausen, Garyville, LA), Kolon GS3500 Super Absorbent Polymer Granules, Kulon, Korea; and ASAP Series (Kandou (Chemdal), Aberdeen, MS). Polymers of superabsorbent particles are also described in detail in U.S. Patents 4,102,340 and Re. 32,649. Examples of suitable SAPs are surface crosslinking Acrylic-based powders such as Starkhausen 9350 or SX FAM 70 (Greensboro, NC). Fibers suitable for use in the structure of the present invention may include cellulose or synthetic fibers. Fiber or mixtures thereof. The best is lignocellulose. Also preferred are cotton fluff pulp, chemically modified cellulose (such as cross-linked cellulose fibers), and highly purified cellulose fibers (such as Buckeye HPF (each commercially available) (From Buckeye Technologies Inc., Memphis, Tennessee)). Staple fiber 20-dimensional can be mixed with synthetic fibers, such as polyester (such as PET), nylon, polyethylene, or polypropylene. The fiber-containing sheet may also include a thermoplastic bonding material, which may be mixed with cellulose or synthetic fibers. Suitable thermoplastic bonding materials include thermoplastic fibers, such as bicomponent thermoplastic fibers ("bico"). Better thermoplastic adhesion 17 583001 300, description of the invention Knot fibers can provide improved adhesion to a wide range of materials, including synthetic and natural fibers, granules, and synthetic and natural carrier flakes. Typical thermoplastic bi-component: The fiber has Celbond type 25S 雔 八 八 main eight bi-component fiber (from Houqisite_Silanis). 5 # Its suitable thermoplastic fibers include polypropylene, polyester, resistant, and other dilute hydrocarbons or these modified products. The preferred thermoplastic fiber is FiberVisions type AL-adhesive_c bicomponent fiber, which includes a polypropylene core and an activated copolyolefin protective layer. When the matrix fibers are cellulose or synthetic fibers (or a mixture thereof), each of the thin layers 10 disposed between the thin layers of functional particles may preferably contain about 1 to 20 gsm of synthetic fiber cellulose. The thermoplastic adhesive material may be present in the thin layer in an amount of 2 to 50% by weight based on the total weight of the thin layer, more preferably 3 to 20%, and most preferably about 10%. Most preferably, the thin layer between the thin layers of the functional particles comprises 3.0 gsm of short fiber pulp and 1.0 g of two components. 15 Adhesives In addition to the thermoplastic fibers discussed above, other suitable adhesives that can be used in the structure of the present invention include those in liquid form or with a liquid carrier, including latex adhesives. Useful latex adhesives include copolymers of ethyl acetate and acrylate, ethylene vinyl acetate copolymers, styrene butadiene 20 carboxylate copolymers and polyacrylonitrile, and Air Products Co., Ltd. (Air Products Inc.), for example, hacked cards sold under the trade names Airbone, Akflex and Vinac, Goodrich Chemical Co. ( Hycar) and Geon, and Fulalex 18 583001 of the Fuller Company 玖, description of the invention. Furthermore, the 'dancing agent may be a non-milk dancing agent such as epichlorohydrin and the like. The invention contemplates two separate adhesive applications. In a first application, an adhesive is applied to the structure so as to be in contact with only areas or lines that are free of particles (which-the package 3 is arranged between the first and second layers of areas or lines). The adhesive can be applied in the form of a spray, foam or mist. In a preferred embodiment, the adhesive can be diluted to contain 3 to 25% solids, more preferably 6 to 12% solids, and most preferably a small pore environment with a high degree of compaction in areas without particles. (For the formation of a bifurcation in 10), the adhesive to be diluted may ideally have a relatively high solids content (such as 10%). The environment can produce rapid capillary action, and the high solids content reduces the adhesive's drift to other areas of the mesh fabric. The first application of the adhesive includes applying the adhesive in the form of a foam, spray, or mist 15 to substantially the entire surface of the structure (as a "integral adhesive") to reduce dust from falling outside the structure and On the inside. In a preferred embodiment, the bulk adhesive is diluted to contain 1 to 200/0 solids, more preferably 2 to 100/0 solids, and even more preferably 2 to 4% solids, and Optimum is about 3.5% solids. Since the adhesive will penetrate to reduce dust out and fix the functional particles, it will not provide a significant contribution to the structural integrity of the mesh fabric. The use of two adhesive applications allows the hardness of the sealed area and the hardness of the unsealed area to be controlled independently. The hardness of any area can be controlled by selecting the type of adhesive, the solid content, and the amount of adhesive applied to each area. 19 583001 玖, description of the invention. This satisfies the need for a seal strength required for transportation and sufficient flexibility to maintain user comfort. The fibers of the structure of the present invention 5 may be suitably fixed using heat-activated fibers or other binders to provide a bulk to the structure. In some embodiments, a thermoplastic bonding material is used and a seal is formed when the structure is compacted or densified by pressure or pressure and heat. The seal can be further enhanced by subsequent hardening in a hardening oven. It is preferred to use thermoplastic fibers as the binder fibers and heat as the hardener. Heat may be applied to harden the fibers at the end of the air-sinking process or periodically during different stages of the process. In another embodiment, the seal may be provided by applying a liquid adhesive (or an adhesive in a liquid carrier) after compacting or densifying the mesh fabric. In this specific embodiment, the target 15 of the adhesive is to contact the particle-free area and avoid the particle area. The adhesive will suck into the dense area and form a seal after drying and hardening. Furthermore, in these embodiments, the upper and lower layers may optionally include a thermoplastic bonding material. In another specific embodiment, the seal can be formed by applying only 20 cloths of a liquid adhesive (or an adhesive in a liquid carrier) in the non-granular area, where the adhesive will suck into the dense Area, and a strong seal is formed after drying and hardening without densifying the particle-free area. In a preferred embodiment, an adhesive can be applied by compacting or densifying the 'particle-free area' (the goal is to contact the particle-free area 20 583001 玖, the invention description, and avoiding the particle area) A seal is formed. The adhesive will suck into the dense area of the ancient sea and form a seal after drying and hardening. In these preferred embodiments, each of the upper and lower layers includes a thermoplastic adhesive material that can enhance the seal after densification and hardening. 5 The heat seal is essentially free of functional particles, and the resulting seal is stronger than a seal with particles at the sealing interface. When the structure of the invention suffers from liquid damage, there are essentially no particles (such as SAP particles) in the sealed area (which swells and interrupts the integrity of the seal). In some embodiments of the invention, the object is an absorbent body. The fibrous structure with improved particle loadability can be transported in the form of a roll-like commodity (or in other packaging forms such as hanging), and can be used in particular as an absorbent core for disposable absorbent objects, such as diapers, adults Incontinence pads, short tight pants, and feminine tampons. The air sedimentation structure of the structure of the present invention 15 The structure of the present invention is preferably prepared as an air sedimentation mesh fabric. The air-settling mesh fabric can typically be prepared by disintegrating or defibrating a cellulose pulp sheet or sheets (typically by hammer milling) to provide individualized fibers. This individualized fiber is then conveyed by air to a forming head on a two-air ✓ drop-mesh fabric forming machine. Some manufacturers 20 have machines for making this air-settling mesh fabric, including m & J Fibretech of Denmark and Dan-Web (also Denmark). The forming heads include a rotating or agitating drum (usually a bearing raceway structure) which can be provided to maintain fiber separation until the fibers are pulled by a vacuum device to a small-hole condensation drum or a small-hole forming conveyor ( Or into 21 583001 玖, invention description (v line). Other fibers, such as synthetic thermoplastic fibers, can also be introduced into the forming head via a fiber feed system that includes a fiber opener, a feed unit, and an air conveyor. If multiple layers (such as distribution and acquisition layers) are desired, individual forming heads can be provided for each type of layer. In a specific embodiment of Che Fengjia, the materials and structures of the present invention include a carrier tissue. A compaction roll may optionally be used before introducing the grain area to eliminate the need for the thin fabric. As contemplated by the present invention, one or more forming heads of the air-settling mesh-forming machine can distribute the desired fibers to the lower layer of the absorbent structure. 10 Then, SAP fine particles or other particles are applied to the upper surface of the mesh fabric. The particles have been coated in a line in the machine direction with a particle-free area or line in between. Other particles include odor control agents (e.g., ' zeolite or calcium carbonate), flavors, detergents, and the like. A second layer is then formed over the top of the lower layer of the coated particles. Then another thin layer of SAP fine particles or other particles is applied to the upper surface in the lane. The lines are coated so that the fine particles do not overlap with the fine particles in the thin layer containing the particles below. Later, alternating layers of fibers and fines can be added as desired. Fig. 6 illustrates a 20 process for manufacturing a fibrous mesh fabric according to the present invention. Alternatively, a carrier tissue 20a can be released from the supply roller 21 and the tissue 20a can be rolled to the division net 18. The thin fabric may additionally be used as a carrier for an absorbent object or as the lower thin layer 16. As contemplated by the present invention, the forming head 24 of the airborne mesh fabric forming machine may distribute the desired fibers to form the lower layer 16 of the absorbent structure. Cellulose fibers can be obtained by decomposing or defibrating 22 583001 玖, a cellulose pulp cypress flake or a family of thin "to obtain (typically by key milling) to provide ㉟ individualized fibers. Then, the The individualized fiber air is delivered to a forming head on an air-settling mesh fabric forming machine. The cellulose fibers and optional thermoplastic fibers can be added to the 5 cellulose thin fabric 20a through the forming head 24. Some preparations Commercially available machines for the formation of the air-settling mesh fabrics, including M & J Fibritek from Denmark and Tian Zhibo (also Denmark). The forming head consists of a rotating drum or a cymbal usually constructed with a raceway structure. Device, which is provided to maintain fiber separation until the fibers are pulled by a vacuum garment onto a small hole with a coagulation 105 or a small hole forming forming machine (or forming, thread). For example, in In the machine manufactured by Britek, the forming head includes a rotary agitator on a screen. It can also be fed through a fiber feeding system (which includes a fiber opening machine, a feeding unit and an air conveyor). Other fibers (such as Synthetic thermoplastic 1 ± fiber) is introduced into the forming head. If you want multiple thin layers (such as a staple fiber 15 knives; I layer and _ synthetic fiber acquisition thin layer), you can provide multiple forming heads ( Each type of thin layer). In the clip formed by the pair of calender rolls 26, these fibers can be selectively compressed to the desired thickness and density. The lower thin layer 16 can be compacted at this point in the manufacturing process In order to close the holes of the mesh fabric (if the particles are fine), and 20 can prevent overflow to the forming line. The particles can be applied to the lower thin layer 16 by using a particle applicator 28. Therefore, the SAP can be finely divided. Granules or other particles are applied to the upper surface of the lower thin layer 16. Referring now to FIG. 7, the particles can be coated in a number of lanes 6 in the machine direction, of which no grain area or 8 lanes Located between the granule lanes 23 583001 发明, description of the invention. These lanes are areas where particles are specifically transported. Other suitable granules include odor control agents (eg, zeolites or calcium carbonate), perfumes, detergents and the like The second thin layer of fibers 18 can be coated by the forming head 34, The head can be coated with 5 cellulose fibers and optionally a thermoplastic fiber (such as a bicomponent fiber). Several layers can be added continuously on top of the second layer. After coating the second thin layer, The mesh fabric can be passed under another particle applicator 28 (not shown) to coat another thin layer of particles, and then another layer of fibers (not shown) is coated by another forming head 34. In this method In this process, the mesh 10 fabric can build up a desired number of alternating layers of fibers and particles. In the process of the present invention, a series of ovens are used to dry, harden or heat bond. The air is allowed to settle into the mesh fabric 23 Heat in the oven 50 to a temperature range of 25 to 80 ° C. When thermoplastic fibers (preferably 15-dimensional bicomponent fibers are included), the hardening temperature and residence time must be sufficient to melt the Fibers and cause sticking. At 52, an overall adhesive is applied to the air-settling mesh fabric 23. This adhesive can be applied by spraying, foaming or misting, and can be applied to reduce dust falling on the surface of the structure. The air-settling mesh fabric 23 is heated in the second oven 54 to a range of 125 20 to 180C. The air-settling mesh fabric 23 can be treated within a pressure range of about 15 psi, preferably 15 psi. As a result of this process, a heat seal can be formed between the thermoplastic material and the fibers of the upper and lower layers. The heat seal is substantially free of particles (especially sAps) and can break the heat seal after exposure to moisture. Then, this finished mesh weave 24, the invention description is rolled into a drum for future use. The fibrous mesh fabric of this continuous belt can be torn or cut into cutting units to form individual absorbent objects, which are not depicted in this figure. The heat-sealed portion of the finished mesh fabric can optionally be torn or perforated to create a narrow-gap core material that is heat-sealed along the two edges. The heat seal to be ripped must be wide enough to provide two effective seals after tearing. In other specific embodiments, the rhenium comprises different other layer coatings of other types and fiber amounts above or below the upper and lower layer structures of the present invention. For example, the 10 'absorbent object may also include a top sheet that is liquid permeable and a back sheet that is impermeable to liquid. Typical absorbent objects that can be formed from the absorbent core of the present invention include diapers, feminine napkins, and adult incontinence products. A typical specific embodiment of the main investigation support is manufactured on the air sedimentation pilot 15 with three forming heads (which has been added to the between-the-head SAP feeding system) manufactured by Dangweibo. 2, 4 and 5. To obtain more than three layers, the structure can be made by passing the mesh fabric through the forming process more than once. On each pass, the material is slightly pressurized at the end of the wire. At the last pass, adjust the final thickness. With the aid of the dividing box, the SAP powder is placed 20 in individual lanes, as shown graphically in Figure 9, which covers approximately half the area of the air & descent forming line. In the following example, the width of the divider is 1.27 cm and the width of the space between the dividers is 127 cm.

The second layer is manufactured by first manufacturing a layer 10 on a cellulose carrier, then feeding the first SAP in the lane, then layer 2 and then the second SAP in the lane. The SAP from the two SAp feeders will cross the machine direction from the first sap. The position of the feeder line SAP is complementary, so the material is viewed from the top along the z dimension (which is perpendicular to the machine direction and the cross machine direction). The SAP line from 15 consecutive feeds will not be overprinted. together. This use is provided below in reverse order to make the compositions of Examples 1, 2, 4 and 5. For a particular SAP feed, the SAP amount in grams per square meter (gsm) is the overall basis weight of the feed. Because the sap is placed in the lane, the amount of continuous places of SAP in the machine direction of the parent fork can be changed from zero or about zero (20 between SAP lanes) to about 100% (in these lanes) .

15 SAP carrier: 18gsm cellulose Flexibility As used herein, "flexibility" is the amount of reverse force required to bend a sheet of material of the invention. As the force required to bend the sheet increases, the flexibility of the thin 20 sheet decreases. Flexibility can be measured by the following procedure using a Gurley tester (model 4171, Gurley Precision Instruments, Troy, NY). 1. Cut the sample to 1 inch x 3.25 inches as accurately as possible. If there is a clear machine direction and reciprocating direction of 30 玖, the invention description, cut a sample in each direction and test each sample. 2. Install the conventional clamps as shown in Figure 3 above the original clamps provided by the Gurley testing machine, and tighten the small upper thumbscrews to ensure safety 5 (see Figure 2, which illustrates Known for clamps with higher basis weight and bulky flakes). The conventional clamp has been designed in a manner that does not change the thickness of the test material, where the material is embedded in the clamp. If the clamping result is changed to / thickness 1, the properties of the structure will change and the results obtained using the Gurley tester will be affected. In this method, the clamp 10 of Fig. 3 is used to eliminate this unwanted effect. 3. Open the adjustable plate of the known clamp by loosening the long lower thumbscrew. The sample is placed in the clamp by sliding the sample up until it touches only the original sweetness. Here, a 20-inch sample should be contained in a conventional clamp. 15 4. Adjust the known clamp height by loosening the height adjustment screw on the original clamp. Adjust the height so that there is a 10-inch gap between the point at which the sample exits the conventional clamp and the point at which the sample will contact the lever arm. 5. Ensure that the remaining 0.25 inch sample will extend below the top of the lever's 20 arm. Make sure that the lever arm does not move. Depress the motor button to move the sample toward the cup arm. Keep pressing the motor button until the sample passes the lever arm. When this is done, observe and note the highest number that reaches that level. Repeat this in the opposite direction. 6. Average a value paid. In the conversion diagram on the device, a sample of 31 玖 has been issued, and the present invention is now a sample with a width of 1.5 inches of English leaves. This factor depends on the distance between the weight used and the distance from the center of the lever arm It depends. The U.S. 25 inch sample using this conventional clamp test is consistent with the ^ 1.5 leaf x 1.5 inch sample that was not tested using the conventional clamp. Without a familiar shot, a sample of 0.25 inches is in the original clamp, and G.25 inches extends below the top of the lever f and the inch is between this distance. If a conventional clamp is used, the same amount of 0.25 inch is used in the conventional clamp; when the conventional clamp is used, the thicker sample is appropriately stabilized at 75 inches. The same distance extends 0.25 inches below the top of the lever arm, and the same distance 丨 inches. 7. Multiply the average reading at that level by the appropriate conversion factor found on the graph. The result is hardness expressed in milligram power (mg). Here the flexibility (ρ) is defined according to the following formula: P = 106/9 · 81 * Hardness. As a result, P is here expressed as 1 per Newton (1 / N).

It has been found that folding the structure described in the present invention results in a significant improvement in its acquisition properties. This improvement can be illustrated by, but not by way of limitation, the examples summarized in Table 3. Based on these results, when the folded sample is a folded structure (see Figure 11), we can see that the performance of the folded structure is better than the unfolded sample with the same overall basis weight. These improvements have significantly shorter acquisition times and also lower rewetting values.

The effect of treated Flystad® (TFF) on capacity and collection use Molly Kell from Hartmann As a control product, MoliCare Plus AI diapers were added. The absorbent is in three layers (a shredded fiber acquisition layer, an SAP short fiber layer, and a short fiber back layer against the multi-back sheet) 10. The diapers were disassembled by carefully peeling the short fiber back layer from the SAP short fiber layer. Then, the SAP staple fiber layer was peeled from the coating slurry and the shrunk fibers. Then, the air-settling core was placed on the short fiber backing layer and covered with the crimped fiber and the top sheet. The crimped fibers are not removed from the top sheet. One of the insert cores (i.e., Example u) contains Frye staples 15 as the cellulose fiber component, while the other contains the treated Flye staples. The air settlement width of the obtained absorption system 1 inserted was 3 cm and its length was 66 cm. The results in Table 4 clarify the performance of the treated Fleece® in the absorption system U consisting of the top sheet, the shrunk fiber layer, the air-settling insert, the staple fiber, and the multi-back sheet. influences. As can be seen from the data, the collection of each instance of processed Frysta® 5 was significantly faster than that of Example 11 containing Frylon®.

In this example, the air-settling core is first C-folded as shown in Figure 11, and then it is placed on the back of the staple fiber and covered with the shrunk fibers and the top sheet. The crimped fibers are not removed from the top sheet. One of the insert cores (which is the C-fold of Example 11) contains Frylon staple fiber 10 as the cellulosic fiber component, while the other (Example 15) contains treated Fleece®. The air-settling insert is 13 cm wide and 66 cm long. The results in Table 5 clarify that the treated Ferry staples ^ and 0: _ are folded in the absorption system 2 (which consists of the top sheet, the shrunk fiber layer, air sedimentation insert 15 staples, staple fibers and many more End sheet composition). As can be seen from the information, the collection of Example 15 containing the processed Fry staple fiber fold was significantly faster than the collection of Example 11 containing the Fly staple fiber C-fold. Samples containing treated Flystad® fibers have also improved capacity (more than samples containing Flystad®). 46 20 583001 发明, Description of the invention Table 5 Core material from the example, SAP fiber absorption system 2 liquid intake time, C-fold in seconds (see Figure 11) Type% First time Second time Third time 11 SXM 70 75 FF 64 161 265 15 SXM 70 75 TFF 50 119 190 The effect of bonded collection plywood and treated Flystad® on the liquid uptake of folded high SAP air sediment in the entire absorption system 5 In order to make a bond Collection pad.
