Abstract
The fibrillation tendency of lyocell fibre can be reduced by application to the fibre of a solution of a chemical reagent which contains at least two aliphatic aldehyde groups capable of reacting with each other in aqueous solution to form a cyclic hydrate containing a --CHOH--O--CHOH-- linkage, followed by reaction between the fibre and the reagent. The protection afforded by the invention is retained upon repeated laundering.
