捻度与合股数对纱与纱磨损耐磨性的影响

Effects of Twist and Number of Ply on Wear Resistance of Yarn-yarn

传统的耐磨性测试主要探究纱线与其他物体摩擦的规律,为了探究纱线与纱线之间磨损的规律,提出了纱与纱磨损测试的概念并以现有条件构建测试装置;在此基础上,通过试验印证棉纱在这种磨损形式下的耐磨性受捻度与合股数的影响。结果表明,随着捻度的增加,单纱及股线的耐磨性均先升高后降低;随着合股数的增加,耐磨性获得显著提升。

The traditional wear resistance test mainly studied the friction between the yarn and other objects,in order to explore the abrasion regular between yarn and yarn,the concept of yarn-yarn abrasion test was proposed and the test device was constructed under existing conditions.On this basis,effects of twist and number of ply on the wear resistance of cotton yarn were confirmed by experiments in this form of wear.The results showed that with the increase of twist,the wear resistance of single yarn and plied yarn increased first and then decreased.With the increase of the number of ply,the wear resistance was significantly improved.
