  • Patent number: 6761957
    Abstract: The ability to transport body liquids in consumer products such as diapers, incontinents and feminine napkins is a key factor in their performance. This invention is designed to provide specific high fluxes (volume of liquid/(time*mass of polymer) of aqueous liquids in designated directions using bundles of new specially designed fibers. The key factors for the bundles are a high specific adhesion for the liquid of interest, a high specific volume of the bundle itself, and alignment of the fibers within the bundle. The invention includes novel liquid acquisition/distribution systems and absorbent products that include a liquid acquisition/distribution system which may incorporate the novel bundles of fibers.

  • Patent number: 6605349
    Abstract: A deformable, shrinkable fiber that is dimensionally stable at normal body temperatures of approximately 37° C. in the dry state, but is dimensionally unstable (i.e. shrinks and distorts) when wet at the same temperature. The fiber comprises a fiber forming polymer that has a dry glass transition temperature (“dry Tg”) of greater than or equal to 42° C. and a wet glass transition temperature (“wet Tg”) of less than or equal to 32° C. A method of making said fiber and absorbent article(s) made therefrom are also disclosed.

  • Patent number: 6344595
    Abstract: The invention provides synthetic polymeric fibers which have utility as temporary acquisition/distribution absorbent structures and permanent storage/distribution absorbent structures in a wide range of absorbent products such as diapers, feminine napkins, and adult incontinent pads. These fibers are short, highly distorted, and bulky characterized by lengths between 2 and 37 mm, short-range distortion factors between 5 and 70, long-range distortion factors between 0.05 and 0.9, and single fiber bulk factors between 0.5 and 10.0. They may or may not have capillary channels on the surface. The advantages of these materials are their increased absorbency, reduced wet collapse at low densities, reduced rewet, reduced loss of liquid under pressure, and their ability to be desorbed by distribution materials such as capillary channeled fibers or by conventional storage materials such as fluff pulp or superabsorbent polymer fiber or powder.
