Abstract: The present invention relates to a fiber-reinforced cement based or cementitious material, and process for making, where the reinforcing fiber is a chemically treated cellulose or non-cellulose fiber. The fiber reinforced cementitious material includes (i) cement, (ii) optionally, sand, aggregate, or sand and aggregate, and (iii) chemically treated fibers having a polyvalent cation content of from about 0.1 weight percent to about 5.0 weight percent based on the dry weight of the treated fibers. The present invention further provides for a fiber reinforced cementitious material having a weak acid content of from about 0.5 weight percent to about 10 weight percent based on the dry weight of the treated fibers.

Abstract: 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.

Abstract: 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/m2 and 140 g/m2, preferably between 75 g/m2 and 110 g/m2, 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.

Abstract: The present invention provides cellulose fibers having low median desorption pressures and low water retention values (WRV), which exhibit improved drainage and fluid flow properties. These fibers are particularly well suited for use in acquisition, distribution, and acquisition-distribution layers, or in absorbent core structures. One embodiment of the invention is a method for preparing cellulose fibers by refining cellulose fibers to a freeness ranging from about 300 to about 700 ml CSF and crosslinking the refined fibers. Another embodiment of the invention is fibers crosslinked with at least one saturated dicarboxylic acid, aromatic dicarboxylic acid, cycloalkyl discarboxylic acid, bifunctional monocarboxylic acid, or amine carboxylic acid. A crosslinking facilitator, such as oxalic acid, may be present during the crosslinking reaction to improve the efficacy of the crosslinking agent. Yet another embodiment of the invention is an absorbent core comprising SAP particles and reversible crosslinked fibers.
