超柔软棉纤维色纺纱开发及性能优化

Development and Properties Optimization of Super Soft Colored Cotton Spun Yarn

从棉纤维原料柔软处理、纺纱工艺优化、合股纱捻向调整3方面,对棉纤维色纺纱进行超柔软处理。通过煮练、染色、后处理等工艺对色棉纤维进行柔软处理,进一步通过纱线原料合理选配、细纱工艺优化及细纱设备改造,以及调整色纺纱复捻捻向,开发18 tex×2(32^S/2)5股复捻超柔软低捻棉纤维色纺纱。纱线手感柔软、持久,适用于制作超柔软棉色纺纱针织毛衫,使毛衫产品具有羊绒般的穿着舒适感。

The super-softening treatment of colored cotton fiber spun yarn was carried out from three aspects,including softening treatment of raw materials, optimization of spinning process and twist direction adjustment of plied yarn. The colored cotton fibers were softened by scouring, dyeing and post-treatment. Furthermore, through rational selection of raw materials, optimization of spinning process and modification of spinning equipment, as well as adjustment of twist direction of double twisted yarn, 18 tex×2(32^S/2) five composite super soft low twist colored cotton fiber spun yarn was developed. The yarn feels soft and durable, which is suitable for making super soft colored cotton fiber spun yarn knitted sweater with cashmere-like wearing comfort.
