A process for the treatment of non-keratinaceous textiles, preferably cellulosic fibres, which comprises the step of treating the textiles with a composition comprising: a polymer comprising at least one protected thiol group, wherein the protecting group is labile under domestic washing conditions, and a textile compatible carrier. Under domestic washing conditions the polymer forms reactive thiol groups which are capable of causing covalent cross-linking of the polymer. Preferably, the thiol group is protected as an isothiouronium group.
L'invention concerne un procédé de traitement de textiles non kératiniques, de préférence des fibres cellulosiques. Ce procédé comprend l'étape consistant à traiter les textiles avec une composition comprenant: un polymère comprenant au moins un groupe thiol protégé, le groupe de protection étant labile dans des conditions de lavage domestique, et un excipient compatible avec les textiles. Dans des conditions de lavage domestique, le polymère forme des groupes thiols réactifs pouvant provoquer la réticulation covalente dudit polymère. De préférence, le groupe thiol est protégé en tant que groupe isothiouronium.
