ABSTRACT:
An alloyed regenerated cellulose fiber containing an alkali metal or ammonium salt of a copolymer of an alkyl vinyl ether and an ethylene dicarboxylic acid or anhydride is prepared by a process wherein the copolymer is mixed with a viscose solution and the mixture is spun through a spinneret into a suitable spin bath and processed into staple fibers adapted to be used in non-woven absorbent articles such as diapers, tampons, sanitary napkins, wiping cloths and the like. The alloyed regenerated cellulose fiber of the invention has increased fluid absorbency characteristics over fibers of the same regenerated cellulose composition without the alloying material.
