製纖維素纖維之核芯（通常稱爲”絨毛”或”紙漿，，，係以化學 黏著劑或經由物理性纏繞及壓擠而結合在一起）及背面片 材。此等個別成分於製造期間經合倂以製得最終物品。 表面片材及擷取層爲個別的成分，作爲分散液體，可使 得液體轉移至較大核芯區域及輔助維持穿戴者皮膚之乾燥 感。表面片材及擷取層係爲吸收性物品不引人注意的成 分，通常由異於吸收性核芯之材料組成，並且有極少至無 吸收容量之趨向。 吸收性核芯係經設計以吸收及保留液體。已嘗試許多努 力以提高纖維素纖維核芯之吸收容量及吸收速率。已添加 顆粒及粉末形式之超吸收聚合物至用完即丟尿布及女性衛 生棉核芯中，俾改良物品之吸收容量及吸收速率。於尿布 結構之情形中，例如超吸收劑粉末或顆粒係於尿布製造程 序期間以吸收性核芯材料篩選。許多問題與超吸收劑粉末 有關。超吸收劑顆粒非常細，且於加工期間有形成空中傳 5 312/發明說明書(補件)/92-〇4·921〇2398 592734 播的趨向。超吸收劑顆粒通常亦不會黏附於基板上，且於 製造、運送、處理、使用（或其組合）期間有移動或轉移的 趨向。超吸收劑顆粒之移動可能在某些區域造成不足的液 體貯存容量以及在物品其他區域造成過度的液體貯存容 羹。 纖維素纖維核芯之缺點爲其於濕潤、乾燥及兩者之條件 下具有弱完整性。經設計以額外的加壓及壓紋法改良纖維 素纖維核芯完整性，通常造成具有不良吸收速率之較硬核 芯。此外，於製造纖維素纖維核芯期間，鬆散的纖維形成 空中傳播且可能引起安全上的危害。 空氣成網（airlaid)或預製的吸收劑核芯提供較薄的核芯 產品，且降低了至少部分與鬆散纖維素纖維加工有關的問 題，但有缺乏完整性之趨向。通常使用化學黏著劑以改良 空氣成網核芯之完整性。然而，化學黏著劑會趨向負面影 響核芯吸收速率及吸收容量。 【發明內容】

[Technical Field to which the Invention belongs] The present invention relates to a nonwoven fabric having a superabsorbent region. [Prior art] Absorbent articles, such as disposable diapers and feminine hygiene articles, usually contain multiple layers, including a surface sheet, an acquisition layer, and a core of pressed cellulose fibers (commonly referred to as "fluff" "" Or "pulp," which is bonded together with chemical adhesives or through physical winding and extrusion) and backsheets. These individual ingredients are combined during the manufacturing process to produce the final article. Surface sheets and The capture layer is an individual component. As a dispersion liquid, the liquid can be transferred to a larger core area and assist in maintaining the dryness of the wearer's skin. The surface sheet and the capture layer are unobtrusive components of the absorbent article , Usually composed of materials different from the absorptive core, and has a tendency to have little to no absorption capacity. Absorptive cores are designed to absorb and retain liquids. Many attempts have been made to increase the absorption capacity of cellulose fiber cores And absorption rate. Superabsorbent polymers in the form of particles and powder have been added to disposable diapers and cores of feminine napkins to improve the absorption capacity of articles Absorption rate. In the case of a diaper structure, for example, superabsorbent powder or granules are screened with an absorbent core material during the diaper manufacturing process. Many problems are related to superabsorbent powders. Superabsorbent particles are very fine and are processed During this period, there was a tendency to form airborne 5 312 / Invention Specification (Supplement) / 92-〇4 · 921〇2398 592734. Superabsorbent particles usually do not stick to the substrate, and are used in manufacturing, transportation, processing, and use (Or a combination thereof) during the movement or transfer. Superabsorbent particles may cause insufficient liquid storage capacity in some areas and excessive liquid storage capacity in other areas of the article. Disadvantages of cellulose fiber cores It has weak integrity under wet, dry, and both conditions. It is designed to improve the integrity of cellulose fiber cores with additional compression and embossing methods, often resulting in harder cores with poor absorption rates. In addition During the manufacture of cellulose fiber cores, loose fibers form airborne transmission and may cause safety hazards. Airlaid or The manufactured absorbent core provides a thinner core product and reduces at least part of the problems associated with the processing of loose cellulose fibers, but there is a tendency to lack integrity. Chemical adhesives are often used to improve the air-laid core. Integrity. However, chemical adhesives tend to negatively affect core absorption rate and absorption capacity.

The present invention relates to a non-woven fabric that can be constructed to provide a fluid capture function, a fluid distribution function, and a fluid storage function. Non-woven fabrics make it possible to build absorbent articles, such as personal hygiene articles, where a single component provides fluid capture, fluid distribution, and fluid storage. Other features of the present invention will be made clearer by the description of the following preferred specific examples and the scope of subsequent patent applications. [Embodiment] (Term) According to the present invention, these terms have the following meanings: "Superabsorbent polymer precursor" means a polymer which can be used as a superabsorbent polymer when crosslinked. "Superabsorbent polymer" refers to a polymer that can absorb water that is several times the weight of the polymer. (Details) Non-woven fabric contains synthetic polymer fibers, contains superabsorbent polymer 9 3U / Invention Note (Supplement) / 92-〇4-92102398 592734, and extends from the first surface of the fabric to the depth of the fabric (ie thickness ), And a second region that does not contain a superabsorbent polymer and enters the depth of the fabric from the second surface of the fabric, the second surface is relative to the surface of the fabric. The first and second regions continuously traverse the length and width of the fabric, and the depth of the fabric extending into the fabric is preferably less than 100% of the fabric depth. It is also preferable that the second regions are adjacent or substantially adjacent to each other. The superabsorbent polymer containing the first region is also referred to herein as the superabsorbent region. The superabsorbent region is preferably impregnated with a superabsorbent polymer, that is, the superabsorbent substance is present in the superabsorbent region throughout the three-dimensional matrix of the fabric. Superabsorbent polymers can be present on fibers in this area, on fabric voids in this area, or on a combination thereof. The depth to which the superabsorbent zone extends into the fabric is referred to herein as the superabsorbent zone. The superabsorbent zone extends into the fabric to a depth sufficient to provide the required absorption capacity and absorption rate for the intended use. The receiving area of the fabric preferably contains about 10% to about 70% by weight of superabsorbent polymer, more preferably about 10% to about 70% by weight of superabsorbent polymer, and about 30% to about 60% by weight. % Superabsorbent polymer. The superabsorbent zone of the fabric exhibits a good salt water absorption effect (under load Ί high saline absorption capacity and high water absorption capacity. The saline absorption capacity under the superabsorbent zone of the fabric is 0.3 psi per square inch (p si) load 10 g of 0.9% saline solution per gram of superabsorbent polymer is preferred, 15 g of 0.9% saline solution per gram of superabsorbent polymer is more preferred, and 0.9 g of saline solution per gram of superabsorbent polymer is most preferred. The superabsorption zone also exhibits a water absorption capacity of at least 20 grams of water per gram of superabsorption zone within 10 periods. 312 / Invention Specification (Supplement) / 92-〇4-921〇2398 First extension first and extension first Aggregate superabsorbent content in medium-thick articles, the best;), the current load is at least 20 minutes, more preferably 10 592734, preferably at least 40 grams of water per gram of superabsorbent zone, and most preferably at least 70 grams of water / G superabsorption zone. The second region that does not contain the superabsorbent polymer may have a thickness that prevents the gel formed when the superabsorbent polymer is in contact with the liquid from coming into contact with the wearer. Areas that do not contain superabsorbent polymer can extend into the fabric deep enough to provide a soft touch. The thickness of the fabric without superabsorbent polymer regions may be sufficient to provide fluid capture, fluid dispersion, or a combination thereof. The non-woven fabric is preferably a high-bulk non-woven fabric, that is, a non-woven fabric having a density of not more than 0.001 g / cm3. The three-dimensional structure of the high bulk nonwoven fabric matrix includes channels (such as pipes) through which liquids (such as water, blood, and urine) can pass, such as wicks. When a liquid comes into contact with a superabsorbent polymer, the superabsorbent polymer begins to swell. In some embodiments, the fibers of the high bulk nonwoven fabric and the high bulk nonwoven fabric swell when exposed to water. The three-dimensional nature of the high bulky matrix and fabric swelling can accommodate liquids present in the fabric, liquids moving into the fabric, and swollen superabsorbent polymers. Fabric swelling allows nonwoven fabrics to absorb larger volumes than nonwoven fabrics (and generally two dimensions) with relatively high density. The three-dimensional matrix of the high bulk nonwoven fabric also helps to maintain a swollen (ie gelled) superabsorbent polymer in the fabric matrix. Preferably, the superabsorbent polymer gel does not move out of the high bulky matrix and does not transfer or move during use of the absorbent article. Nonwoven fabrics exhibit good dry strength and maintain strength and integrity when wet. Nonwoven fabrics exhibit a preferred dry tensile strength of at least 2 000 g / 2 5.4 mm, more preferably at least 2500 g / 2 5.4 mm, and an optimal dry stretch 11 312 / Invention Specification (Supplement) / 92-04 -92102398 592734 has a strength of at least 300 g / 25.4 mm and a wet tensile strength of at least 150 g / 25.4 mm, more preferably at least 400 g / 25.4 mm, and most preferably at least 500 g / 25.4 mm. Non-woven fabrics are preferably those having a basis weight greater than 22 g / m 2 in terms of fabric thickness (ie, calipers) of at least 1 millimeter (mm), preferably at least 30 g / m 2, more preferably at least 60 g Per square meter, more preferably at least 80 grams per square meter, and most preferably at least 100 grams per square meter. Depending on its applicability, the thickness of the high-loft nonwoven fabric can be changed. Suitable high-loft nonwovens have a thickness of at least 10 mm, and more preferably at least 15 mm. The high bulk nonwoven fabric also has a density of not more than 0.01 g / cm3, preferably about 0.002 g / cm3 to about 0.009 g / cm3, and more preferably about 0.007 g / cm3 to about 0.009 g / cm3. Cm. Other useful non-woven fabrics having bulkiness have a density of not more than 0.025 g / cm3 and not more than 0.023 g / cm3. Nonwoven fabrics include, for example, polyesters, polyolefins (such as polypropylene, polyethylene, and copolymers of polyolefins and polyesters), polyamides, polyurethanes, polyacrylonitrile, and combinations thereof Copolymers, bicomponent (such as outer core) fibers and combinations thereof) synthetic polymer fibers. Nonwoven fabrics may also contain regions (relative to a fiber composition of another region) with different polymers or polymer combinations. The superabsorbent region of the fabric may contain superabsorbent polymer fibers. Non-woven fabrics are preferably elastic and contain elastic fibers such as polyester fibers. Fibers can be warped and can be mechanically and physically entangled. Various methods (including air-laid, wet-laid, loosening and carding, melt-blowing, melt-spinning, and spunbond technologies and combinations thereof) can be used to form nonwoven fabrics. Each of the 12 312 / Invention (Supplement) / 92-04-92102398 592734 bonding systems can be used to bond the fibers of the nonwoven fabric ' including thermal bonding, mechanical bonding (such as needle punches and hydroentanglement), and combinations thereof. The superabsorbent polymer present in the first region of the nonwoven fabric can absorb water several times its own weight. Preferably, the superabsorbent polymer can absorb water at least 100 times its own weight, and can absorb at least 150 times its own weight, more preferably at least 200 times its own weight. The superabsorbent polymer present in the superabsorbent region may be formed in situ (i.e., in a suitable position on the non-woven fabric), for example, from a water-based superabsorbent polymer composition. The aqueous superabsorbent polymer composition includes a superabsorbent polymer precursor (for example, an alkaline soluble polyelectrolyte) and a crosslinking agent. When the aqueous superabsorbent polymer composition is dried, the absorbent polymer precursor is polymerized to form an absorbent polymer. Particularly effective superabsorbent polymer precursors include polymers of water-soluble monomers. The polymer is preferably an at least partially neutralized polymer derived from an α, β-vinyl unsaturated monocarboxylic or dicarboxylic acid monomer, an anhydride monomer, or a combination thereof with a crosslinking agent. Effective water-soluble α, β-vinyl unsaturated monocarboxylic or dicarboxylic acid monomers include, for example, acrylic acid, methacrylic acid, crotonic acid, maleic acid, maleic anhydride, itaconic acid, fumaric acid, and Its combination. The term "partially neutralized" means that at least some of the neutralized carboxylic acid groups are present in the superabsorbent polymer precursor. The superabsorbent polymer precursor can be completely neutralized. The term "fully neutralized" means that the superabsorbent polymer precursor exhibits a pH greater than 7. Superabsorbent polymer precursors are based on the use of basic metal hydroxides (examples include sodium hydroxide, calcium hydroxide, potassium hydroxide 13 312 / Invention Specification (Supplement) / 92-04-92102398 592734 and combinations thereof ) Adjust p Η to about 5 to about 6. Instead of metal hydroxides, metal alkoxides can be used (examples include calcium hydroxide and potassium hydroxide). Preferably, about 50% to about 95% of the acid groups are first neutralized with the metal hydroxide, more preferably about 65% to about 85% of the acid groups, and most preferably about 75% to about 85% of the acid groups Group, to a pH of 2 to 6, more preferably to a pH of 5 to 6, and then neutralizing the superabsorbent polymer precursor with a volatile, variable alkali metal component (ie, an alkali) to a pH greater than 7, and more preferably It is greater than 7 to 10, and most preferably greater than 7 to 8. The superabsorbent polymer BU which is completely neutralized (that is, 100% of acid groups are neutralized) is obtained. Suitable volatile alkali metal components include, for example, ammonia, triethylamine, dimethylamine, and combinations thereof. Volatile and volatile alkali metal components dissipate when the aqueous component dries. The dissolution of the base releases a sufficient portion of the carboxylic acid groups to the free acid (i.e., carboxylic acid) form, and the carboxylic acid groups can then react with the crosslinking agent. The viscosity of the water-based superabsorbent polymer is preferably about 50 centipoise (cps) to about 50,0 0 0 cps, more preferably about 1 0 0 cps to about 3,0 0 0 cps, and more preferably About 100 cps to about 20,000 cps, preferably about 100 cps to about 10,000 cps, preferably about 100 cps to about 5,000 cps, preferably about 100 cps to about 2, 5 0 0 cps (at a solids content of about 23%). Preferred water-based superabsorbent polymers have viscosities suitable for spray technology, saturation technology, and coating technology. The aqueous superabsorbent polymer preferably contains about 5 to about 65% by weight (preferably about 10 to about 50% by weight, more preferably about 20 to about 40% by weight). Solids. Effective water-based superabsorbent polymers are disclosed, for example, in PCT Patent Application No. 14 312 / Invention Specification (Supplement) / 92-0 Wood 92102398 592734 No. WO 0 0/6 1 642 (Anderson et al.) And US Patent No. 5 , 6 9 3, 7 07 (Cheng et al.) (Incorporated in this case for reference). An effective commercially available water-based superabsorbent polymer was purchased from HB Fuller Com pan y (Vad n is Heights, Minnesota) under the brand name FULATEX PD- 8 0 8 1 -H. A sufficient amount of cross-linking agent was added to the water-based superabsorbent polymer. Among the absorbent polymers, superabsorbent polymers are obtained. Preferably, the crosslinking agent reacts with the functional group on the superabsorbent polymer precursor during drying at ambient temperature (ie, about 20 ° C) or higher temperature for less than 24 hours. Effective cross-linking agents include any substance that will react with the hydrophilic groups of the aqueous polymer. Effective cross-linking agents include, for example, chromium ions, iron aluminum ions, chromium ions, titanium ions, and combinations thereof, and acridine. Various suitable cross-linking agents are disclosed in U.S. Patent No. 4,090,0 1 3 and incorporated herein. An example of an effective commercially available crosslinking agent is B A C 0 T E 2 0 ammonium carbonate, commercially available from Magnesium Elektron Inc. (Flemington, New Jersey). The composition contains a cross-linking agent in an amount of about 2 parts to about 24 parts, more preferably about 4 parts to about 14 parts, and most preferably about 6 parts to about 10 parts (based on the dry ingredient weight) . The composition also contains a chain transfer agent to change the molecular weight of the superabsorbent polymer. Suitable chain transfer agents include, for example, sodium hypophosphite, thioglycolic acid, thiols, such as primary octyl mercaptan, 2-fluorenyl ethanol, n-dodecyl mercaptan, and third dodecyl mercaptan. , Ethyl alcohol, isooctyl thioureidoacetic acid, fluorenyl carboxylic acids and their esters having 2 to 8 carbon atoms, examples include 3-fluorenylpropionic acid and 2-fluorenylpropionic acid, halogenated The hydrocarbons include, for example, carbon bromine compounds (such as carbon tetrabromide and bromochloroform) and combinations thereof. The content of the chain transfer agent may be not more than 5% by weight (preferably 1% by weight to about 4% by weight, and more preferably 5% by weight) 15 312 / Description of the Invention (Supplement) / 92-04-92102398 592734 to about 3% by weight ) Is present in the aqueous superabsorbent polymer composition. The composition may also contain other ingredients, including wetting agents, defoamers, plasticizers, adhesives, and combinations thereof. When dried, it crosslinks to form a superabsorbent polymer. The superabsorbent polymer is applied to a highly bulky fabric in the form of an aqueous superabsorbent polymer composition. Various techniques including, for example, dipping, spraying, printing, coating, and combinations thereof, can be used to apply an aqueous superabsorbent polymer composition to a fabric. The superabsorbent region of the fabric is preferably impregnated with an absorbent polymer, meaning that the superabsorbent polymer is present throughout the fabric matrix. According to different methods, including, for example, air (including, for example, circulating air), high temperature, microwave radiation (that is, radiation in the frequency range of 300 MHz to 300,000 MHz (including, for example, 915 MHz, 2450 MHz, 5800 MHz, and 22,155 MHz), Radio frequency radiation, ultraviolet light radiation, electron beam radiation, and combinations thereof (for example, passing nonwovens through a circulating air oven). Superabsorbent nonwovens can be used in absorbent articles, including, for example, disposable items (that is, items designed to be discarded after use). Effective applications of superabsorbent nonwovens include, for example, cores or components of different absorbent articles, including, for example, disposable diapers, feminine hygiene products (such as sanitary napkins and panty liners), bandages, wound care products, Surgical pads, incontinence items (such as adult incontinence pads and incontinent underwear), clothing (such as training pants, pullovers), chest pads, saliva, sweat pads (such as underarms, wrists, and head), clothing Collar inlays, shoe inlays, and hat inlays (such as hat straps). Superabsorbent nonwovens can be combined with other core materials, including, for example, cellulose fibers and other fluff materials. Superabsorbent nonwoven fabrics can be woven continuously 16 312 / Invention (Supplement) / 92-04-92102398 592734 in the form of an absorbent article, in a discontinuous area of another component of the absorbent article, and combinations thereof. Superabsorbent nonwoven fabrics can be located in different areas and structures or in articles (including, for example, arbitrarily or in a pattern (such as a strip)) and combinations thereof. In a specific example, the superabsorbent nonwoven fabric is located where the superabsorbent region is in contact with the cellulose fibers. In other specific examples, the article contains a plurality of superabsorbent nonwoven fabrics, which are located in areas that are replaced with cellulose fibers. The superabsorbent nonwoven fabric can also be held in place or on an article by the adhesive composition. Wherein, the articles combined with superabsorbent non-woven fabrics may contain other components, including, for example, a body fluid-permeable surface sheet, a capture layer, a second absorbent layer (such as a second core or fiber layer), and a body fluid-impermeable Back sheet and combinations thereof. The surface sheet can be soft, non-irritating to the skin of the wearer. The surface sheet is liquid permeable to allow liquid (such as urine) to pass through its thickness. Suitable surface sheets can be made from a wide range of materials, including, for example, woven and nonwoven fabrics, films, porous foams, porous films, including, for example, perforated films (e.g., vinyl films, polypropylene films, or combination). The surface sheet may be hydrophobic to isolate the wearer's skin from the surface sheet and the fluid contained in the absorbent core. The capture layer preferably disperses liquid on the surface of the core. The second absorbent layer may include loose fibers, fibers bonded together through an adhesive, compressed fibers, and combinations thereof. The fibers of the second absorbent layer can be various components, including, for example, natural fibers (wood pulp, hemp fibers, cotton, silk, wood and combinations thereof), synthetic fibers (including, for example, nylon, polyester, acrylic 17 312 / invention) Instruction (Supplement) / 92-04-92102398 592734 series fiber, polypropylene, polyethylene, polyvinyl chloride, polyurethane and combinations thereof) and combinations thereof. The back sheet can be located away from the wearer's skin and prevents the liquid contained in the absorbent composite from wetting the articles in contact with the absorbent article. The back sheet is liquid impermeable and water vapor permeable. The superabsorbent nonwoven fabric can be located between any two components of the absorbent article, such as between a body fluid-permeable surface sheet and a body fluid-impermeable back sheet, and between a capture layer and a body fluid-impermeable back sheet And their combinations. The superabsorbent region of the nonwoven fabric may be in contact with the cellulose fibers. Superabsorbent nonwovens can also come in contact with the wearer. The invention will now be further illustrated by the following examples. Unless otherwise specified, all parts, percentages, and contents mentioned in the examples are in weight M g. (Example) (Test procedure) The test procedure used in the examples is as follows. (Total water absorption rate) The total water absorption rate (g / g) is the weight of tap water (in grams) absorbed by a 100-square-cm composite sample in 10 minutes. A sample of 100 square centimeters (10 cm x 10 cm) of the dry compound was weighed (WD). The sample was then immersed in tap water for 10 minutes. Place the wet and swollen composite on a pre-weighed metal screen (WS) for 1 minute. Excess water present in the sample was drained. Then weigh the wet sample and screen weight (W / W).

(Total absorption rate of 0.9% saline solution under load) The absorption rate (g / g) of the total 0.9% saline solution is the weight of the saline solution (in grams) per 100 square centimeters of the composite sample in 10 minutes. meter). The absorption of the total 0.9% saline solution was determined by weighing (W D) a dry compound sample of 100 square centimeters (10 cm × 10 cm). Place the sample in a container and place a metal mesh brass weight over the sample. Both the metal screen and weight have the same size as the sample (that is, co-extension), and the total weight of the metal screen and weight must be applied to the sample by 0.3 p s i. Pour a sufficient amount of a total 0.9% saline solution into the container to soak the absorbent sample. After 10 minutes, remove the weight and the metal screen. The absorptive sample weight (WW) was then immediately weighed. The total 0.9% saline solution absorption (AUL) under load was calculated according to the following equation: 0.9% saline AUL = (WW-WD) / WD and reported in grams of 0.9% saline solution / gram complex absorbed. (Dry tensile strength) A 4-inch by 1-inch strip sample composite was cut, and a 1/2 inch strip-shaped masking tape was wound around each 1-inch wide end of the composite strip. Next, place the composite bar in the jaws of an Instr ο η gauging machine (I nstr ο n C 〇rp., Cant ο η, Masachuse 11 s), and cross at 12 inches / minute Head speed measures tensile strength. The average tensile strength of the five samples is reported as dry tensile strength (g / inch).

The composite strip was then immersed in water for 5 minutes, and the excess water was gently patted dry before placing the sample in the jaws of an Instroii tester. Tensile strength was measured at a crosshead rate of 12 inches / minute. The average tensile strength of the five samples is reported as the wet tensile strength (g / inch). (% Superabsorbent polymer (SAP) load) The determination of the% superabsorbent polymer present in the composite is determined by weighing the fabric weight before the superabsorbent polymer treatment and weighing the superabsorbent polymer. The weight of the dried composite after treatment is subtracted to obtain the weight of the superabsorbent polymer in the composite and the weight of the superabsorbent polymer is divided by the total weight of the composite.
