摘　　要：由于假捻纺纱技术作用在普通环锭细纱机上可生产低捻高强纱,为了了解假捻装置应用于不同纱支及纺纱方式的效果,文章采用一种自主研发的假捻装置对纯棉纱进行试纺。通过环锭和赛络两种纺纱方式对不同细度(16S、21S、40S)纱线的不同捻度分别进行有无假捻装置情况下的纺纱,并对强伸性及毛羽性能进行测试,旨在得到假捻装置作用效果明显的纱支、捻度和纺纱方式。实验结果表明:假捻装置对低捻纱的作用效果高于高捻纱;对环锭纺纱的作用效果优于赛络纺;对高支纱效果优于低支纱。Because the false twist spinning technology can produce low-twist high-strength yarns on ordinary ringspinning machines, in order to understand the effect of false twisting devices applied in different yarn counts andspinning methods, a self-developed false twisting device was used to test the cotton yarn. Ring spinning and sirospinning were used to perform spinning with or without false twisting on different degrees of fineness （16S, 21S,40S） yarns, and test the strength, elongation and hairiness performance. The purpose is to get a yarn count, twist,and spinning method with the obvious effect of false twisting device. The experimental results show that the effect offalse twisting device on low twist yarn is higher than that of high twist yarn, the effect on ring spinning is better thanthat on siro spinning, the effect on high count yarn is better than that of low count yarn.
