Abstract
Abstract Textiles, particularly carpets, are endowed with oil and water repellency and soil resistance by treatment thereof with certain detergent-compatible fluorochemical compounds which can also be used in conjunction with anionic or nonionic detergents to provide cleaning/treating compositions for cleaning such textiles simultaneously with the treatment. The textile treating compositions of the invention comprise certain detergent-compatible fluorochemical compounds which are dissolved and/or dispersed in a suitable liquid vehicle. The textile treating/cleaning compositions of the invention also contain an anionic and/or a nonionic detergent.
