摘要: Bibulous cellulosic fibers for use in fibrous structures having an inherently absorptive function, for example surgical dressings, surgical sponges filters, catamenial napkins, tampons and diapers, which bibulous cellulosic fibers, and fibrous structures containing said bibulous fibers in effective amounts, are characterized by greatly improved absorbency for and retention of aqueous solutions, including physiological solutions. The bibulous cellulosic fibers are substantially water-insoluble, wet cross-linked fibrous salts of carboxymethyl cellulose having a sufficiently high degree of carboxymethyl substitution to insure water solubility in the absence of crosslinking. The bibulous cellulosic fibers are produced under conditions which preserve the fibrous form of the cellulose fiber raw material.
