Device for Gradient Wrap of Yarn Hairiness

Abstract

The invention relates to a device for gradient wrap line hairiness in the textile processing technical field. The device is made of erecting bed, pedestal, bracing frame, funneling rubbing device, heat setting device, orientation aspiration channel, first driving pulley, second driving pulley, yarn gatherer, yarn let-off gear (stand). The air inlet of orientation aspiration channel is corresponding with the outer side of the hollow cone outside wall surface, and implement lateral negative pressure-pumping on inner side of the hollow cone not only help to wrap the yarn hairiness orderly in fixed direction, preventing increase of fiber-gathering or yarn fault. Increasing hairiness holding strength of hollow cone side and diameter of the upper cone wall obviously exceeds that of the lower cone wall and diameter of the hollow cone, help to realize gradient wrapping of yarn hairiness, high-speed and high-efficiency looping, heat setting device carries out slot extruding and high-temperature shaping to yarn after plumage looping, increasing stability and consistency of looping structure.

Description

technical field [0001] The invention relates to a device for gradient wrapping yarn hairiness, which belongs to the technical field of textile processing. [0002] technical background [0003] Hairiness is one of the important indicators to measure the quality of yarn. Yarn hairiness not only affects the production efficiency of weaving, knitting and other post-processes, but also affects the appearance quality of the final product. Especially today, when high-speed shuttleless looms are widely used, reducing yarn hairiness is of great significance. [0004] Yarn hairiness occurs in the spinning process. The mechanism is that after the end of the fiber transferred from inside and outside is exposed to the yarn body, it breaks away from the grip of the jaws and cannot re-enter or wrap around the main body of the yarn body, forming hairiness. The hairiness increases in the winding and warping process. The root cause is that there are many hairiness on the surface of the yarn ...

AI Technical Summary

Problems solved by technology

The yarn wrapped by progressive high-efficiency hairiness through the hollow cone immediately enters the ironing yarn trough of the heat setting device, and is subjected to trough extrusion and high temperature heat setting to further increase the stability and stability of the yarn hairiness wrapping structure. The structure is dense, which solves the technical problems of the yarn surface hairiness winding structure loosening and the yarn hairiness rebounding in the subsequent processing process in the previous hairiness reduction technology
