  • Patent number: 7288167
    Abstract: The invention provides a method for preparing cross-linked cellulosic fibers. A sheet of mercerized cellulosic fibers with a purity of at least 95% is treated with a solution containing a carboxylic acid cross-linking agent. The treated cellulosic fibrous material is dried and cured in sheet form to promote intrafiber cross-linking. Cross-linked fiber products produced are economic and possess good porosity, bulking characteristics, wet resiliency, absorption characteristics, low fines, low nits and low knots. The invention also includes blended cellulose compositions comprising a minor proportion of cross-linked mercerized cellulosic fibers and a major proportion of other cellulosic fibers. The invention further provides individualized, chemically cross-linked mercerized cellulosic fibers of high purity.

  • Patent number: 6620293
    Abstract: The invention provides a method for preparing cross-linked cellulosic fibers. A sheet of mercerized cellulosic fibers with a purity of at least 95% is treated with a solution containing carboxylic acid cross-linking agents. The treated cellulosic fibrous material is dried and cured in sheet form to promote intrafiber cross-linking. Cross-linked fiber products of this method, which is economic, that possess good porosity, bulking characteristics, wet resiliency, and absorption, low fines, low nits, and low knots, are also disclosed. This invention also includes a blended cellulose composition comprising a minor proportion of cellulose fibers having been similarly cross-linked with carboxylic acids and a major proportion of other cellulose fibers. This invention further provides individualized, chemically cross-linked cellulosic fibers comprising mercerized individualized cellulosic fibers with a purity of at least 95%, cross-linked with carboxylic acids.
