超细羊毛纤维长度对纱线质量指标的影响

Influence of superfine wool fiber length on the yarn quality

对同一批次超细羊毛根据羊毛纤维长度的变化,在同一细纱机上采用同一纺纱工艺方案,测试分析纺纱过程中纱线断头率、条干均匀度变异系数CV、细节、粗节、毛粒、毛羽H、强力等各项指标,通过综合对比测试得出超细羊毛纤维长度几乎影响纱线的所有质量指标,提出超细羊毛的纤维长度对纺纱工艺参数的制定有着重要的影响,同时对改善成纱质量提出了新的方法。

In this paper,some comparative spinning tests have been done with the same batch of superfine wool which has the different length produced in different production parameters.According to the change in the length of the wool fibers,using the same spinning process on the same model of machine,it tested and analyzed all the quality indicators during the spinning process such as the yarn breakage rate,yarn CV,yarn thin,yarn thick,nep,filoplume,strength and so on.Through comprehensive comparative tests,it was found that superfine wool fiber length affects almost all the yarn quality indicators,which mean that the superfine wool length had important impact on the spinning parameters,so that a new method for improving yarn quality was discussed.
