The invention relates to a textile surface for thermal insulation, which is intended, for example, for the production of protective clothing and, in particular, for clothing worn by fire fighters, said thermal surface performing a thermal barrier function. The invention comprises type A heat-stable yarns which display little or no shrinkage under the effect of heat and type B yarns which display shrinkage under the effect of heat. The latter yarns can be used to produce a controlled relief, thereby increasing the insulating power of the textile complexes used for thermal protection. The invention also relates to multilayer complexes comprising said surface.
La présente invention concerne une surface textile pour isolation thermique notamment pour la réalisation de vêtements de protection , en particulier de vêtements d'intervention des pompiers , présentant une fonction de barrière thermique, comprenant des fils de type A thermostables et présentant pas ou peu de retrait sous l'effet de la chaleur , et des fils de type B présentant un retrait sous l'effet de la chaleur ; ces derniers fils permettent la création d'un relief contrôlé augmentant le pouvoir isolant de complexes textiles utilisés pour la protection thermique. L'invention concerne également des complexes multicouches comprenant cette surface.
