A super-clean warping method for hairy yarn

Abstract

The invention relates to a super-smooth warping method of yarns with many drafted fibers and belongs to the textile processing technical field. According to the method of the invention, on each yarn warping mechanism of a warping machine, a false twisting device is adopted to make the trunk of a yarn rotate; a drafted fiber directional stretching device is adopted to directionally eject steam flows so as to directionally stretch the drafted fibers of the yarn, so that some of the drafted fibers of the yarn forwards and orderly wrap the trunk of the yarn, and therefore, the drafted fibers can be prevented from being entangled to from neps when randomly or vertically winding the trunk of the yarn; a drafted fiber vortex wrapping device is adopted to reversely wrap the other drafted fibers of the yarn on the trunk of the yarn, so that the other drafted fibers of the yarn and the forwards and orderly wrapped drafted fibers can be closely tangled in a cross manner; and therefore, progressive complete wrapping and cross tight wrapping of the drafted fibers of the yarns can be realized, and winding tightness and firmness of the drafted fibers can be greatly increased, and the problem of series rebound of the drafted fibers of the yarns in a warping procedure and subsequent procedures of warping can be solved, and super-smooth warping of the yarns with many drafted fibers can be realized. The device of the invention has the advantages of reasonable structure and convenient operation.

Description

technical field [0001] The invention relates to an ultra-clean warping method for hairy yarns, belonging to the technical field of textile processing. [0002] technical background [0003] Warping technology is a process in which a certain number of warp yarns are wound parallel to the warp beam or weaving beam with a suitable and uniform tension according to the specified length and width of the process design. The warping process makes the warp package change from a bobbin to a warp beam or a weaving beam. If the warp beam is made, it will be formed into a weaving beam through the sizing process; if it is a weaving beam, it will be provided to the warp drawing The process directly prepares for the warp system that constitutes the fabric. The warping process is mainly to arrange the yarn better, to ensure that the yarn has no skein, no broken end, no yarn wave, no flying flower, no thread-back, and no wrong branch. After finishing, the yarn is required to be evenly arrange...

AI Technical Summary

Problems solved by technology

However, the existing mechanical and air-flow online yarn hairiness reduction technologies still have fatal technical problems: the smooth yarn obtained by winding the hairiness to the yarn body has a large rebound range of the hairiness during subsequent unwinding processing; during the hairiness reduction process, there are Fiber aggregation leads to a substantial increase in yarn defects such as thick places and neps

It can be seen that the above-mentioned technology is still unable to realize the ultra-clean warping of the raw material of the multi-hairiness package yarn.
