ABSTRACT:
Synthetic fibers such as polyethylene terephthalate and nylon are treated with certain polydiorganosiloxanes to provide improved properties such as "hand" and water repellency. When the polydiorganosiloxanes contain approximately two silicon-bonded amino radicals of the formula --R'(NHCH.sub.2 CH.sub.2).sub.a NHR", such as --CH.sub.2 CH.sub.2 CH.sub.2 NHCH.sub.2 CH.sub.2 NH.sub.2, they provide a crosslinked siloxane on the surface of the treated fiber, when heated, which does not diminish the fire-retardancy rating of the fibers.
