  • Patent number: 7357833
    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.

  • Publication number: 20040224588
    Abstract: 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.

  • Publication number: 20020090511
    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.
