A textile material suitable for use as an automotive upholstery fabric is provided, which comprises: (a) a body portion having a face and a back comprised of synthetic, thermoplastic fibers; (b) said body portion being provided with a substantially oil- and water-repellent fluoropolymer substantially evenly distributed on the face thereof in a minor amount sufficient to improve soil resistance characteristics but less than an amount which would cause said material to burn at a rate in excess of about 2 inches per minute or to support such burning for longer than about one minute; and (c) said textile material further having been backcoated with a flame-retardant backcoating in an amount sufficient to improve the flammability characteristics of said textile material.
A process for imparting soil resistance to polyester-fiber-containing textile materials containing at least 40 percent polyester by weight wherein the flame retarding characteristics of such materials are not substantially adversely affected, which comprises applying an effective minor amount of a substantially oil and water repellent fluoropolymer to the surface of the textile material by means of an engraved roll thereby covering the fibers on and near the surface of the textile material while avoiding substantial penetration of said fluoropolymer into the sections of said material that are neither at or near the surface of said material, drying and curing the resulting fluoropolymer modified textile material.
