A yarn treating composition useful for application to a filamentary yarn for high-speed friction draw-false twisting. This composition comprises substantially a polyether having a molar copolymerization ratio between propylene and ethylene oxides of 35:65--90:10 and an average molecular weight of 1,000 to 15,000, and small amounts of anionic compounds. The anionic compounds are used in the form of a mixture of salts of specific dicarboxylic acid derivatives with phosphate compounds and/or sulfonate compounds. The application of said treating composition to yarns provides a reduction of fluctuation in friction between the yarns and rollers, guides, etc. and of frictional resistance at a high running speed, improvement in threading property in false twisting, and a sharp decrease in scum deposits on heaters.
一种纱线处理组合物,适用于高速摩擦牵伸假捻的长丝纱线。这种组合物主要包括一种聚醚,其丙烯和乙烯氧化物的摩尔共聚比为 35:65-90:10,平均分子量为 1,000-15,000 之间,还包括少量阴离子化合物。阴离子化合物以特定二羧酸衍生物的盐与磷酸盐化合物和/或磺酸盐化合物的混合物的形式使用。在纱线上使用上述处理组合物,可减少纱线与辊子、导纱器等之间的摩擦波动以及高速运转时的摩擦阻力,改善假捻时的穿线性能,并大幅减少加热器上的浮渣沉积。
