Abstract of the Disclosure 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 characteris- tics over fibers of the same regenerated cellulose composition without the alloying material.
