Abstract

Small-particle cellulose ether which has become at least for the most part water-insoluble owing to modification but has remained highly swellable with water is converted into a material convenient for use. This entails the small-particle modified cellulose ether being attached at least on one side on a strip of hydrophilic material as substrate, and the latter being dried. The resulting strips are highly absorbent and show good fluid retention.
