CA 2206378

A method of the invention relates to treating a textile base material for thermobonding interlining, the material being constituted by a woven fabric or a weft knit that includes texturized synthetic threads, in particular air jet texturized threads, which form loops on a top face that is to receive spots of glue, and on an opposite, bottom face. The method consists in subjecting said textile base material (13, 12), prior to applying spots of glue (9) thereto, to emerizing or equivalent pre-treatment on its bottom face (12b) and to pre-treatment on its top face (12a) for reducing the height of the loops, e.g. singeing or heat treatment by radiation or by contact. Preferably, the textile base material is initially subjected to emerizing or equivalent pre-treatment on its bottom face (12b), and subsequently to singeing pre-treatment on its top face (12a).

L'invention consiste en une méthode de traitement de matériau textile pour le thermocollage d'une entre doublure, le matériau étant constitué d'un tissu tissé ou d'un tricot trame incluant des fils synthétiques texturisés, principalement des fils texturisés au jet d'air, formant des boucles sur un côté supérieur sur lequel seront appliquées des gouttes de colle. Le côté opposé inférieur, constituant l'autre face, comporte également des boucles. La méthode consiste à soumettre ladite base de matériau textile (13,12), avant d'y appliquer les gouttes de colle (9), à l'émerisage ou à un prétraitement équivalent sur sa face inférieure (12b), et à un prétraitement sur son côté supérieur (12a) dans le but de réduire la hauteur des boucles, soit en les grillant ou en les traitant thermiquement par rayonnement ou par contact. De préférence, on soumettra initialement la base de matériau textile à l'émerisage ou à un prétraitement équivalent sur sa face inférieure (12b) et ensuite sur sa face supérieure (12a).
