ABSTRACT:
Regenerated cellulose sponges of incresed absorbency and rate of absorption formed by impregnating the sponge material with a solution or dispersion containing from 0.005 to 0.25% of a water-soluble or water-dispersible, high molecular weight, hydrophylic, film-forming polymer, drying the impregnated sponge and compressing it. The presence of the film-forming polymer allows the cutting of desired shaped individual sponges from the treated sponge material with a minimal formation of lint particles on the cut surfaces.
