Abstract

Regenerated cellulose fiber with a reduced tendency to fibrillation can be prepared by treating never-dried fiber with an aqueous solution or dispersion of a polymer having a plurality of cationic ionisable groups. Suitable polymers include those carrying imidazoline and azetidinium groups. The fiber may additionally be treated with an aqueous emulsion of an emulsifiable polymer.
