AI Technical Summary
Technical Problem
Lyocell fibers suffer from whitening due to damage to the fiber sheath and core structure during washing. Existing technologies improve the feel through bio-enzymes or resin finishing, but this increases production costs and environmental pressure.
Method used
By adjusting the yarn twist design and twist spinning method, and combining specific process parameters to optimize the weaving, fabric washing, stretching and pre-shrinking processes, fiber friction and shrinkage stress are reduced, thereby improving yarn strength and fabric smoothness.
Benefits of technology
It effectively reduces fiber skin damage and fabric whitening, lowers production costs, maintains fabric feel and drape, and meets customer standards.

Abstract
本发明属于纺织印染技术领域，具体涉及一种莱赛尔纤维面料洗后原纤化改善的生产方法。包括以下工序：纺纱→织造→烧毛→煮练→液氨→增白 / 染色→拉幅→预缩；所述纺纱工序：单纱捻系数为270‑350；后合股捻系数为600‑750，捻向为ZZ捻。所述后合股采用扭妥纺纺纱方式。本发明通过加捻将多余的毛羽随着捻度的增加束缚到纱线中，同时捻度增加纱线直径减少，在生产加工时纱线与纱线之间、面料与设备之间的摩擦力减少，从而有效减少了纤维皮层，不会被破损故改善了洗后原纤化，又因为合股时采用扭妥纺纱方式，低扭矩，高强力，减少纱线在面料中的收缩应力，从而也减小了面料洗后纬斜的问题。
