Abstract
Abstract A method of treating a synthetic fiber-containing knitted or woven fabric, wherein a synthetic fiber fabric or a blended fabric of synthetic and other fibers is treated with an aqueous mixture of a hydrophilic and thermally reactive urethane prepolymer with its terminal isocyanate groups blocked and (an) organopolysiloxane. This treatment is good for imparting to thermoplastic synthetic fiber goods a durable effect to prevent melting by sliding friction, and, when applied to the treatment of sportswear, it is useful for protecting players from troubles resulting from melting of clothing by friction caused by sliding attempts.
