Title

(EN) METHOD FOR MAKING A CARPET HAVING A COATED SECONDARY BACKING

(FR) PROCEDE DE FABRICATION D'UNE MOQUETTE A SUPPORT SECONDAIRE DOTE D'UN REVETEMENT

Abstract

(EN) This invention relates to a method for making a carpet having a primary backing which is permeable to liquids and a secondary backing which is substantially impervious to liquids. The method involves applying a continuous coating of hydrophobic polymeric latex to the outer surface of a secondary backing material. The hydrophobic polymeric latex coating may be a modified latex containing fluorochemicals mixed therein.

(FR) Procédé de fabrication d'une moquette dotée d'un support primaire perméable aux liquides et d'un support secondaire qui est pratiquement imperméable aux liquides. Ledit procédé consiste à appliquer un revêtement continu de latex polymère hydrophobe sur la surface externe d'un matériau de support secondaire. Ledit revêtement de latex peut être un latex modifié contenant des composés fluorés mélangés au latex.
