The present invention provides finishes for elastic fiber, which attain elastic fiber yarn having superior antistaticity, unwinding and package buildup performance and lubricity, and minimize fly sticking on elastic fiber yarn in knitting operation of elastic fiber yarn and cotton spun yarn to enable high-speed knitting operation of fine elastic fiber yarn and cotton spun yarn; and also provides elastic fiber applied therewith. The finishes of the present invention contain 60 to 99.99 parts by weight of at least one of base components selected from the group consisting of silicone oils, mineral oils and ester oils, 0.01 to 20 parts by weight of amino-modified silicones and 0.0001 to 20 parts by weight of phosphate esters containing at least one hydrocarbon group or oxyalkylene group per a molecule. The elastic fiber of the present invention is characterized by the application of the said finish with 0.1 to 15 weight percent of fiber.
本发明提供用于弹性纤维的整理剂,使弹性纤维纱线具有优越的抗静电性、退绕性和成包性能以及润滑性,并在弹性纤维纱线和棉纺纱线的针织操作中最大限度地减少弹性纤维纱线上的飞粘,从而实现精细弹性纤维纱线和棉纺纱线的高速针织操作;本发明还提供应用了本发明整理剂的弹性纤维。本发明的整理剂含有 60 至 99.99 重量份的至少一种基础成分,这些基础成分选自
硅油、矿物油和
酯类油组成的组,0.01 至 20 重量份的
氨基改性有机
硅和 0.0001 至 20 重量份的
磷酸酯,
磷酸酯每个分子至少含有一个烃基或氧烷基。本发明的弹性纤维的特点是在使用上述整理剂时,纤维的重量百分比为 0.1 至 15%。
