Abstract
Article of manufacture comprising alloy fibers having high fluid-holding capacity, the alloy fibers being comprised of a matrix of regenerated cellulose having carboxymethylcellulose uniformly dispersed therein, the latter being the sole additive for increasing the fluid holding capacity of the fibers.
Claims7
An article of manufacture comprising a highly fluid absorbent mass of alloy rayon staple fibers consisting essentially of a matrix of regenerated cellulose and about 10 to about 40 percent of sodium carboxymethylcellulose b.o.c., at least about three-fourths of the carboxyl groups of said carboxymethylcellulose being in sodium salt form, said fibers having a denier of about one and one-half to six;
- said fibers carrying a lubricating or protective finish in an amount of less than one percent, and said fibers having a fluid holding capacity of at least about 5.5 cc. per gram of fiber as measured by the Syngyna test.
