US 2004/0018787 A1 · Treated textile fabric

Abstract

A method of preparing a stain resistant and water repellant textile fabric comprising: a) treating a textile fabric with an aqueous primary treatment composition comprising at least about 5 weight percent of a fluorochemical textile treating agent, based on the weight of the primary treatment composition; b) drying the treated fabric at an elevated temperature to obtain a primarily treated fabric; c) providing a polymeric film on one side of the primarily treated fabric, the film comprising an aqueous secondary treatment composition comprising at least about 4 weight percent of a fluorochemical textile treating agent, based on the weight of the secondary treatment composition; and d) drying the treated fabric with the film at an elevated temperature to obtain a secondarily treated fabric.
