发明名称 Process for producing regenerated cellulose containing cross linked sodium lignate or sodium lignosulfonate
摘要 Regenerated cellulose products containing formaldehyde cross linked sodium lignate or sodium lignosulfonate in an amount of from about 1% to about 40% by weight based on the weight of the cellulose in the product are prepared by mixing one of the cross linked lignin derivatives or a mixture thereof substantially uniformly in a viscose solution and extruding the solution into a spin bath in which the extruded viscose streams coagulate into filaments containing the cross linked lignin derivative. The extended regenerated product may be used as a fiber in absorbent cullulose products such as diapers, sanitary napkins, tampons and the like.
