Abstract

L’invention concerne un tissu de tricotage/tissé hydrofuge avec perméabilité à l’air réversible. Elle permet d’obtenir des vêtements combinant de telles performances de perméabilité à l’air de sorte que la perméabilité à l’air change de manière réversible et rapidement selon les changements d’humidité à l’intérieur des vêtements et des performances hydrofuges empêchant la pénétration d‘eau de l’extérieur des vêtements. Le tissu de tricotage/tissé comprend 30 % en poids ou davantage de fibres conjuguées gonflables comprenant un composite côte à côte d’un ingrédient extrêmement gonflable avec un ingrédient faiblement gonflable et est pourvu d’un produit hydrofuge. Ce tissu de tricotage/tissé hydrofuge avec perméabilité à l’air réversible peut avoir un caractère hydrofuge de grade supérieur ou égal à 3 et un changement de perméabilité à l’air, que l’on exprime par l’équation : changement de perméabilité à l’air (%) = [(perméabilité à l’air à l’état humide (B) - perméabilité à l’air initiale (A))/perméabilité à l’air initiale (A)]×100, supérieur ou égal à 10%. On l’obtient en soumettant un tissu de tricotage/tissé comprenant des fibres conjuguées gonflables comprenant un composite côte à côte d’un ingrédient extrêmement gonflable avec un ingrédient faiblement gonflable à un traitement destiné à conférer un caractère hydrofuge, avant froissement pour l’infiltration du produit hydrofuge.
