摘要： To prevent body fluids from flowing backward through a liquid-permeable topsheet for use in body fluids absorptive goods, the topsheet is formed by a nonwoven fabric made of thermoplastic synthetic fibers appropriately fused together and the topsheet is provided with openings and a skin-contacting region continuously extending around the openings. A first zone of the topsheet has a water-resistance at least in the skin-contacting region which is higher than a water-resistance in a second zone extending outside the first zone so as to suppress a back flow of body fluids possibly occurring in the skin-contacting region.

摘要： A binder is applied to particles which are then combined with fibers to bind the particles to the fibers. The particles have functional sites for forming a hydrogen bond or a coordinate covalent bond. The fibers have hydrogen bonding functional sites. The binder comprises binder molecules, the binder molecules having at least one functional group that is capable of forming a hydrogen bond or a coordinate covalent bond with the particles, and at least one functional group that is capable of forming a hydrogen bond with the fibers. A substantial portion of the particles that are adhered to the fibers may be adhered in particulate form by hydrogen bonds or coordinate covalent bonds to the binder, and the binder in turn may be adhered to the fibers by hydrogen bonds. Fibers containing particles bound by this method are easily densified.

摘要： Binder is applied to fibers during the production of a web on a wet laid sheet manufacturing line. Particles are bound to fibrous material by a binder that has a volatility less than water, wherein the binder has a functional group capable of forming a hydrogen bond with the fibers, and a functional group that is capable of forming a hydrogen bond or a coordinate covalent bond with the particles. The binder may be activated or reactivated by addition of heat, liquid, or mechanical energy such that fibers treated with binder may be shipped to a distribution point before particles are bound to the fibers. The binder may be a polymeric binder selected from the group consisting of polyethylene glycol, polypropylene glycol, polyacrylic acid, polyamides and polyamines, and in which the polymeric binder has a hydrogen bonding functionality or coordinate covalent bond forming functionality on each repeating unit of the polymeric binder. Alternatively, the binder may be a non-polymeric organic binder that includes a functionality such as a carboxylic acid, an alcohol, an amino acid, an amide, and an amine, wherein there are at least two such functionalities on the molecule, which may be the same or different functionality. Particles attached to the fibers in this manner are firmly adhered and are not easily dislodged. Fibrous products produced by this method include fibers to which particles are bound and may also include other fibers.

摘要： Particles are bound to fibrous material by a polymeric binder selected from the group consisting of poly(caprolactone) diol, polyamides and polyamines. The polymeric binder has a hydrogen bonding functionality or coordinate covalent bond forming functionality on each repeating unit of the polymeric binder. As a specific example, the fibrous material is cellulosic fibers and the particles are superabsorbent particles. Preferably 3-80 percent binder and 0.05-80 percent particles, by weight of the total weight of the fibrous material, binder and particles are included. The binder preferably has a molecular weight greater than 500 grams/mole, preferably 4,000-8,000 grams/mole. Particles attached to the fibers in this manner are firmly adhered and are not easily dislodged. Fibrous products produced by this method include fibers to which particles are bound, and fibers which have been treated with the binder but to which particles are not bound.

摘要： The present invention provides absorbent articles, especially sanitary napkins, containing a fluid transport layer. In-use, the transport layer directs menses to a storage layer, thereby minimizing product failure and staining of undergarments. The transport layer can protrude into, or through, a topsheet to provide very aggressive transport of vaginal discharges. Preferably, the transport layer is a layer of fibers having external capillary channels.

摘要： A core component for use in a fluid-absorbing article, such as a diaper, incontinence pad, catamenial device or the like is described, which core component has a plurality of core zones comprising a zone of vulnerability positioned in said core component for maximum potential exposure to wetting, and at least one additional core zone arranged in an area of reduced potential exposure to initial wetting and in direct or indirect fluid receivable relation from the zone of vulnerability. The zone of vulnerability has a wadding component comprising synthetic fiber of filament and has a greater average pore size and greater average fractional value of fiber volume to fiber surface area than the average pore size and average fractional value of fiber volume to fiber surface area of the wadding component in the at least one additional core zone. When two or more additional core zones are used, the average fractional value of fiber volume-to-fiber surface area and the average pore size within the wadding components of the additional core zones decrease in value from zone to zone with increased distance from the zone of vulnerability and with reduced risk of initial wetting. The wadding component in the zone of vulnerability may be further characterized by having a greater average liquid-solid contact angle than the average liquid-solid contact angle in the wadding components in the additional core zones. A fluid absorbing article and a method for increasing fluid receptivity, fluid storage efficiency, and reduced rewet characteristics utilizing the core component of the invention are also described.

摘要： Binder is applied to fibers during the production of a web on a wet laid sheet manufacturing line. Particles are bound to fibrous material by a binder that has a volatility less than water, wherein the binder has a functional group capable of forming a hydrogen bond with the fibers, and a functional group that is capable of forming a hydrogen bond or a coordinate covalent bond with the particles. The binder may be activated or reactivated by addition of heat, liquid, or mechanical energy such that fibers treated with binder may be shipped to a distribution point before particles are bound to the fibers. The binder may be a polymeric binder selected from the group consisting of polyethylene glycol, polypropylene glycol, polyacrylic acid, polyamides and polyamines, and in which the polymeric binder has a hydrogen bonding functionality or coordinate covalent bond forming functionality on each repeating unit of the polymeric binder. Alternatively, the binder may be a non-polymeric organic binder that includes a functionality such as a carboxylic acid, an alcohol, an amino acid, an amide, and an amine, wherein there are at least two such functionalities on the molecule, which may be the same or different functionality. Particles attached to the fibers in this manner are firmly adhered and are not easily dislodged. Fibrous products produced by this method include fibers to which particles are bound and may also include other fibers.

摘要： A topsheet for use in a disposable absorbent article. The topsheet is divided into three trisections disposed in a particular arrangement along the longitudinal axis of the disposable absorbent article. The front trisection has no elastic extensibility. The central trisection has elastic extensibility in the transverse direction. The rear trisection has elastic extensibility in the longitudinal direction. If desired, the topsheet may be further provided with an aperture for communicating fecal material through the topsheet into a void space in the disposable absorbent article. An exemplary disposable absorbent article is also included in the disclosure.
