ABSTRACT:
An absorbent material is provided having exceptional fluid suction and holding power for aqueous physiological fluids, and which is thus especially adaptable for use as tampons, sanitary napkins, baby diapers, hospital pads and the like. The material consists essentially of cellulose fibers containing from 5 to 20% by weight of sodium carboxymethyl cellulose. The material is formed by a process in which a viscose spinning solution is produced from cellulose xantogenate by dissolving in aqueous caustic soda solution and permitting the solution to ripen, spinning the latter in an acid spinning bath, and then cleaning and drying the resultant threads, the spinning solution containing 5 to 20% by weight of sodium carboxymethyl cellulose.
