The present invention provides for twisted and rectangular dice forms of sheeted fibrous materials and a process for making the dice forms. Specifically, the invention teaches the use of dice forms and sheet materials in construction and cementitious materials. 

System for delivery of fibers into concrete

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.

Cementitious material reinforced with chemically treated cellulose fiber

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.

A layered composite suitable for disintegration into superabsorbent cellulose fluff suitable for use as a core material in an absorbent product. The composite includes a wetlaid web of cellulosic fibers; a layer of superabsorber disposed on the wetlaid web; a drylaid cellulosic layer disposed on the superabsorber layer; wherein the layer of superabsorbent particles comprises greater than 50 percent by weight of the composite; and the drylaid cellulosic layer does not include a bonding agent.
