ABSTRACT:
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 extending 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 cellulose products such as diapers, sanitary napkins, tampons and the like.
