摘要: 重点讨论了同相纱和相位纱的捻度结构特征以及两种自捻纱线的性能差异。从自捻纱线的结构特征来看,自捻纱线一个周期长度上存在三种纱段:有捻-有捻纱段,有捻-无捻纱段和无捻-无捻纱段。相位差的存在就是使得无捻-无捻纱段的长度减小。相位差的大小c值接近或等于无捻区长度b值时,无捻-无捻纱段长度最小,所形成自捻纱线均为有捻-有捻纱段和有捻-无捻纱段,是自捻纱线结构中性能最好的纱段。实纺相位纱和同相纱的性能比较结果表明,相位差c值约等于无捻区长度b值时,自捻纱线强度和伸长性能较好。

Abstract: The difference of the twist structure and properties in in-phase self-twist yarn and phased yarn is mainly discussed. There are three kinds of yarn zones: twist-twist zone, twist-zerotwist zone, zerotwist-zerotwist zone, existing in one cycle length of self-twist yarn. The existence of phase difference decreases the zerotwist length in yarn. When the phase difference (value c) is close or equal to the length of the twistless area (value b), the length of zerotwist-zerotwist zone obtain an minimum so that the best properties of self-twist yarn can be achieved. The test results of spun in-phase and phased self-twist yarn are accordance with the above conclusion.

Key words: self-twist , twist distribution , in-phase , phase , rubbing twist
