Abstract
The inventive fabric treatment agent can impart excellent hydrophilicity to fabric materials of, in particular, synthetic fibers with durability and launderability. The principal ingredient of the agent is a copolymer composed of three types of moieties including (a) a diorganopolysiloxane terminated at both molecular chain ends each with a non-silanolic hydroxy group or other active hydrogen-containing group, e.g. --SH, --COOH and --NH.sub.2, (b) a polyol compound having polyoxyalkylene linkages which is typically a polyoxyethylene glycol and (c) a diisocyanate compound which serves as a coupling agent between the moieties (a) and (b).
