Abstract
Condensation-polymer fibers, such as polyethylene terephthalate fibers, and cellulosic fibers, such as cotton, have their surface modified with certain polydiorganosiloxanes to provide improved properties such as water repellency, hand, and tear strength to fabrics comprising the treated fibers. The polydiorganosiloxanes must contain at least two silicon bonded HSR'-groups wherein R' is a divalent or a trivalent saturated hydrocarbon radical or at least one HSR'-group and at least one --OR" radical bonded to silicon. Exemplary is a polyester fabric which is treated with an aqueous emulsion of ##STR1## and dried to provide a textile having improved hand.
