Abstract

Procedure for obtaining hydrophilic structures based on a water-insoluble, fiber-forming and sheet-forming polymer, characterized in that the preparation uses particles of modified cellulose ether, which, being only etherified, would itself be soluble in water, but which by modification has become at least for the most part insoluble in water, but remaining capable of accepting water.
