Description

Low-hairiness low-torque spinning device

Technical Field

The application relates to a spinning device, in particular to a low-hairiness low-torque spinning device.

Background

The yarn needs to have certain torque to ensure that the yarn has certain strength, but excessive residual torque can cause the cloth cover of the fabric to be inclined, and is harmful torque. In order to reduce or even eliminate the residual torque of the yarn, a wide variety of torque balancing methods have been developed. In principle, there can be broadly divided into two broad categories: permanent treatment and physical torque balance. The permanent treatment method is mainly used for converting elastic torsional deformation of the yarn into plastic deformation so as to achieve the purpose of releasing residual torque. The method mainly adopts heat treatment, chemical treatment, humidification treatment and the like. This treatment requires additional energy consumption and may also cause environmental pollution. Furthermore, for some fibres, permanent treatment does not completely eliminate the residual torque of the single yarns, which may cause damage and destruction of the fibres. The physical torque balance method has certain advantages relative to permanent treatment, and is a purely mechanical treatment technology. The method utilizes the structure of the yarn to balance the residual torques generated by different yarns, and the yarn still keeps the elastic deformation characteristic. The currently widely used methods in the industry mainly include two methods: reversely plying and twisting two same single-strand yarns, wherein the number of the added twists is the same as that of the single strands; or two single yarns with the same twist count are fed in opposite directions.

These methods all have a certain effect of reducing the torque of the yarn by mechanical treatment, but also have a certain damage to the fiber and a damage to mechanical properties such as strength of the yarn. Therefore, it is necessary to develop a spinning device which can reduce the yarn torque without damaging the yarn.
