PURPOSE:To provide the title agent causing no gelling or gumming, giving excellent lubricity without yellowing when imparted on fibers, comprising each specific organopolysiloxane and diorganopolysiloxane. CONSTITUTION:The objective stable treating agent causing no gelling, gumming and opacifying during storage, heating and/or treating, comprising (A) 100-0.1wt.% of an organopolysiloxane of the formula (R is monovalent hydrocarbon; R<1> is divalent hydrocarbon; X is 200-2000; Y is 1-100) and (B) 0-99.9wt.% of a diorganopolysiloxane free from nitrogen atom-substituted monovalent hydrocarbon. This agent is, either directly or in the form of a solution or emulsion, applied on a fibrous material by e.g., spraying, thus imparting said material with excellent lubricity without yellowing. Said organopolysiloxane can be prepared by hydrochloric acid elimination reaction between a halogenated alkyl group-contg. organopolysiloxane and cyclohexylamine. |
