Gore Tex est le nom commercial d'une membrane imperm\u00e9able \u00e0 l'eau et en m\u00eame temps ouverte \u00e0 la diffusion de la vapeur d'eau. Il a \u00e9t\u00e9 nomm\u00e9 d'apr\u00e8s le chimiste am\u00e9ricain Robert W. Gore, qui l'a invent\u00e9 en 1969. Son composant principal est le polyt\u00e9trafluoro\u00e9thyl\u00e8ne qui est \u00e9galement le composant chimique du t\u00e9flon. Pour cr\u00e9er la membrane microporeuse, le PTFE est prolong\u00e9 de mani\u00e8re thermom\u00e9canique. Cette technique de fabrication \u00e9tait la principale invention de Robert W. Gore.<\/p>\n
La membrane fonctionne ainsi : ses pores sont environ 20 000 fois plus petits qu'une goutte d'eau, ce qui la rend imp\u00e9n\u00e9trable contre elle. Pour la mol\u00e9cule de vapeur d'eau, il n'y a aucun probl\u00e8me \u00e0 traverser les petits pores, car ils sont plus petits que les mol\u00e9cules d'eau liquide. Cela rend le tissu Gore Tex parfait pour les textiles, car ils peuvent \u00eatre imperm\u00e9ables et coupe-vent, mais aussi respirants. Ce n'\u00e9tait pas possible auparavant, car il n'y avait pas de mat\u00e9riaux qui offraient les m\u00eames caract\u00e9ristiques. Il n'y avait que des tissus qui \u00e9taient \u00e9tanches, mais pas respirants. Par exemple du plastique ou des textiles cir\u00e9s. Les premiers textiles avec la membrane Gore tex ont \u00e9t\u00e9 produits et vendus en 1976, apr\u00e8s que l'inventeur ait obtenu le brevet sur le mat\u00e9riau.<\/p>\n
Le principal inconv\u00e9nient du Gore Tex est qu'il n'est fonctionnel que lorsque la pression osmotique entre l'un et l'autre c\u00f4t\u00e9 de la membrane est suffisamment \u00e9lev\u00e9e, ce qui signifie que la diff\u00e9rence de temp\u00e9rature doit \u00eatre suffisamment \u00e9lev\u00e9e. Ainsi, la membrane Gore Tex sur un v\u00eatement commun cessera d'\u00eatre respirant lorsque la temp\u00e9rature ext\u00e9rieure est sup\u00e9rieure \u00e0 15-18 \u00b0C. Ainsi, la sueur se condensera \u00e0 l'int\u00e9rieur de vos v\u00eatements et vous serez mouill\u00e9 \u00e0 l'int\u00e9rieur.
De toute fa\u00e7on sur les textiles il n'y a pas que la membrane Gore Tex qui les rend imperm\u00e9ables.<\/p>\n
Si seule la membrane brute \u00e9tait utilis\u00e9e, les produits ne seraient pas tr\u00e8s durables. Ainsi, les fabricants utilisent un \u00ab\u00a0sandwich\u00a0\u00bb de diff\u00e9rents mat\u00e9riaux pour prot\u00e9ger la membrane centrale. Ces mat\u00e9riaux doivent \u00e9galement \u00eatre respirants, car s'ils ne le sont pas, cela n'aurait aucun sens d'utiliser du Gore Tex entre eux. Deux mat\u00e9riaux de protection ext\u00e9rieure typiques sont le polyester et le nylon, qui sont suffisamment solides pour r\u00e9sister aux dangers de l'utilisation quotidienne. Sur la face int\u00e9rieure du textile, il y a surtout une protection, et en plus un mat\u00e9riau qui rend le tissu confortable \u00e0 porter, comme le molleton.<\/p>\n
Ainsi, aujourd'hui, vous pouvez obtenir n'importe quel type de textile qui utilise les avantages du tissu Gore Tex. Par exemple des vestes, des gants, des chaussures, des pantalons etc\u2026 Mais aussi d'autres domaines utilisent les caract\u00e9ristiques exceptionnelles, par exemple il est \u00e9galement utilis\u00e9 pour les implants m\u00e9dicaux, l'isolation des fils, les filtres ou plusieurs parties de v\u00e9los.<\/p>","protected":false},"excerpt":{"rendered":"
Gore Tex is the trade name of a membrane which is impermeable against water and in the same run open to the diffusion of water vapor. It was named after the US-American chemist Robert W. Gore, who invented it in 1969. Its main component is the polytetrafluoroethylene which is also the chemical component of Teflon.
