氨纶汗布横条问题分析及预防

Analyzes of Hor izontal Stripe Defect of Spandex Plain-knitted Fabric and Its Preventive

针对氨纶汗布在生产过程中出现横条造成光坯布质量等级下降,甚至造成整批布报废的问题,从原料横、机器横、工艺异常3个方面详细分析氨纶汗布出现横条的原因。主要包括如纱线条干不均匀、混批织造、黄白纱;设备制造的精度不高、主要零部件磨损不均匀;以及工艺编织时压针不均匀,氨纶输送器输送氨纶不均匀等,并针对各种横条问题给出相应的解决措施。相关生产企业在生产过程中,必须及早发现、正确解决,从源头开始减少和消除造成横条的各种因素,对于已有一定数量的毛坯情况,可以将毛坯用作染白色、印花、绣花或小裁片等,从而将损失降低到最少。

In terms of the problem of gray fabric poor quality and the full clothes scrapping caused by horizon-tal stripe defect of spandex plain-knitted fabric, the paper analyzes the main causes of horizontal stripe defect from material,machine and technology,such as the bad yarn evenness, the mixed batches knitting and yellow and white yarn of raw materials; the low manufacture precision and parts wearing uneven of machine; the press uneven, spandex feed instability of knitting technology and so on. In addition, the resolve measures have been presented in detail. The enterprises should discover these problems early and solve correctly, besides that, to eliminate or mini-mize the varies causes is key points to reduce the production costs.
