Patent

CA 2484555

The present invention provides a hydrophobic, oleophobic and stain resistant fabric comprising a woven, non-woven, or knitted fabric substrate coated with a polymer system comprising a scrub resistant first layer and a second layer comprising a fluoropolymer bonded to the scrub resistant first layer. A method for producing a hydrophobic, oleophobic and stain resistant fabric including the steps of selecting a suitable fabric substrate and applying first layer to form a scrub resistant first layer; drying and curing the scrub resistant first layer; applying a fluoropolymer coating over the first layer to form a second layer; and drying and curing the second layer. Articles comprising a fabric as described herein are also provided.

L'invention concerne un tissu hydrophobe, oléophobe et résistant aux taches, qui comprend un substrat de tissu tissé, non tissé ou tricoté enduit d'un système polymère comprenant une première couche résistante au frottement et une seconde couche comprenant un polymère fluoré lié à la première couche résistante au frottement. L'invention concerne également un procédé de production de tissu hydrophobe, oléophobe et résistant aux taches, qui consiste à choisir un substrat de tissu approprié et à appliquer une première couche de façon à former une première couche résistante au frottement; à sécher et traiter la première couche résistante au frottement; à appliquer un revêtement polymère fluoré sur la première couche de façon à former une seconde couche; et à sécher et traiter la seconde couche. L'invention concerne également des articles renfermant un tissu tel que spécifié dans le descriptif.
