Patent

CA 2429644

A process for the treatment of non-keratinaceous textiles, preferably cellulosic fibers, which comprises the step of treating the textiles with a composition which comprises: a self-crosslinking polymer and a nucleophilic species (preferably a polymer comprising at least one protected thiol group), and a textile compatible carrier. Under domestic washing conditions the polymer forms reactive thiol groups which are capable of causing covalent cross-linking with the polymer. Preferably, the thiol group is protected as an isothiouronium group.

L'invention concerne un procédé utilisé dans le traitement de tissus non kératiniques, de préférence des fibres cellulosiques, qui consiste à traiter les textiles avec une composition contenant un polymère d'auto-réticulation et une espèce nucléophile (de préférence un polymère comprenant au moins un groupe thiol protégé), et un support compatible avec le textile. Dans des conditions de lavage domestique, le polymère forme des groupes thiols réactifs qui sont capables de réaliser une réticulation covalente avec le polymère. Le groupe thiol est, de préférence, protégé comme un groupe isothiouronium.
