Abstract

L'invention concerne une matière pour structure de film, qui comprend un tissu de base comprenant une fibre de verre comme matière primaire, et une couche de surface en résine fluorée, formée sur la surface du tissu. La matière est caractérisée en ce que la couche de surface contient une poudre de catalyseur incolore et transparente, ou blanche, dans un état exposé. Le photocatalyseur est de préférence un dioxyde de titane du type anatase qui possède une forte activité de photocatalyse, et la résine fluorée est de préférence un copolymère de tétrafluoréthylène-hexafluoropropylène. Cette matière pour structure de film permet de décomposer et d'éliminer une tache contenant une matière organique collée, par décomposition ou hydrophilisation induite par photo-oxydation, et possède ainsi de bonnes propriétés antisalissures pendant une longue durée. Ladite matière permet en outre de supprimer l'électricité statique produite et accumulée par frottement ou abrasion, dus au vent ou analogue, ou au contact avec une autre matière, et entraîne une réduction des matières collées telles que poussière, sables fins ou analogue formant une tache.
