Abstract
The fibrillation tendency of solvent-spun cellulose fiber is reduced by treating the previously dried fiber with a chemical reagent containing at least two functional groups which are reactive with cellulose and which are electrophilic carbon--carbon double bonds, particularly vinyl sulfone groups, or precursors thereof or electrophilic three-membered heterocyclic rings or precursors thereof. The chemical reagent is preferably colorless and is preferably applied to the fiber from aqueous solution. The fiber may be contained in a woven or knotted fabric.
