High permeability curly fibers with enhanced fiber strength are produced by mercerizing cellulosic fibers. The fibers have relatively high values for curl, kink level, wet tensile strength, and bulk density when compared with current fibers. The disclosed fibers can be used in a wide range of applications including paper products such as filters.

High-permeability cellulose fibers

The present invention is directed to an absorbent material and the fibers therein, having two or more layers including an upper surface layer which has on the outer surface of the layer one or more surface area zones which are more wettable zones and adjacent thereto one or more less wettable zones, where the more wettable zones have a greater hydrophilicity than the less wettable zone. The present invention is also directed to the fibers therein, which contain polyvalent cation-containing compounds and fatty acid containing compounds. The present invention also provides for methods of treating fibers or solid materials and processes of producing the hydrophobic materials.

Fibers of variable wettability and materials containing the fibers

Disclosed are absorbent structures for use in disposable absorbent products for absorbing bodily fluids, wherein the absorbent structure includes a fluid storage layer including matrix fibers and a superabsorbent polymer for receiving fluids and a distribution strip positioned below the fluid storage layer. The distribution strip includes cellulosic fibers and has a basis weight of between 45 grams per square meter and 140 grams per square meter and a density of between 0.20 grams per cubic centimeter and 0.60 grams per cubic centimeter.

Distribution strip for absorbent products

Disclosed are absorbent structures including fibers bound with a polyvalent cation-containing compound and superabsorbent polymer particles. The fibers exhibit an ion extraction factor of at least 5%. Also disclosed are multi-strata absorbent structures, such as disposable absorbent articles, including the treated fibers and SAP particles. Further disclosed are methods for preparing absorbent structures including the treated fibers; structures including fibers combined with a polyvalent cation-containing compound; and methods for treating or coating SAP particles with polyvalent cation-containing compounds.

Absorbent structures of chemically treated cellulose fibers

Disclosed are absorbent structures for use in disposable absorbent products for absorbing bodily fluids, wherein the absorbent structure includes a fluid storage layer including matrix fibers and a superabsorbent polymer for receiving fluids and a distribution strip positioned below said fluid storage layer. The distribution strip includes cellulosic fibers and has a basis weight of between 45 grams per square meter and 140 grams per square meter and a density of between 0.20 grams per cubic centimeter and 0.60 grams per cubic centimeter

An absorbent structure which includes a fluid storage layer comprising matrix fibers (e.g., cellulose fluff fibers) and superabsorbent polymers positioned above a distribution strip. The strip comprises cellulosic fibers (e.g., cotton linters, mercerized cellulose, fluff pulp, or chemically treated cellulose) having a basis weight of between 45 g/m and 140 g/m , preferably between 75 g/m and 110 g/m , and a density of between 0.20 g/cc and 0.60 g/cc, preferably between 0.25 g/cc and 0.55 g/cc. The absorbent structure may also comprise a fluid pervious top sheet and a fluid impervious back sheet. The structure may be used in diapers, feminine hygiene pads or adult incontinence pads.
