The invention relates to a method for functionalising a textile substrate using an active composition, said method comprising the following steps: preparing a formulation of microcapsules containing the active composition in an envelope, said envelope being based on a material containing a type of group reacting under an ionising radiation, and said formulation further comprising at least one cross-linking bonding agent having two types of groups reacting under an ionising radiation; impregnating the textile substrate with the microcapsule formulation; applying an ionising radiation to the impregnated textile substrate in order to carry out the cross-linking bonding of the microcapsules on said substrate by reaction of the reactive groups. The invention also relates to a functionalised textile substrate obtained by said method, and to a textile item made from such textile substrate.
L'invention concerne un procédé de fonctionnalisation d'un substrat textile au moyen d'une composition active, ledit procédé comprenant les étapes prévoyant de : préparer une formulation de microcapsules contenant la composition active dans une enveloppe, ladite enveloppe étant à base d'un matériau comprenant un type de groupement réactif sous rayonnement ionisant, ladite formulation comprenant en outre au moins un agent de pontage présentant deux types de groupements réactifs sous rayonnement ionisant; imprégner le substrat textile avec la formulation de microcapsules; appliquer un rayonnement ionisant sur le substrat textile imprégné de sorte à assurer le pontage des microcapsules sur ledit substrat par réaction des groupements réactifs. L'invention concerne également un substrat textile fonctionnalisé par mise en AEuvre d'un tel procédé, ainsi qu'un article textile confectionné avec un tel substrat textile.
