Abstract
The invention provides a novel method for imparting water-repellency to a woven fabric such as velveteen by use of a silicone-based water-repellent agent. In addition to water-repellency, the fabric treated by the inventive method has many excellent characteristics required in a fancy fabric as well as susceptibility to bonding with a lining cloth by use of a hot-melt adhesive. The water-repellent agent used in the method comprises, in addition to an organohydrogenpolysiloxane, either one or a combination of a linear organopolysiloxane, in which at least 5% by moles of the organic groups are alkenyl, e.g. vinyl, groups, and a resinous organopolysiloxane composed of the monofunctional organosiloxane units and tetrafunctional siloxane units SiO.sub.2 in a limited molar proportion.
