Control device and method for yarn hairiness of ring spinning frame

Abstract

The invention provides a control device for yarn hairiness of a ring spinning frame, which comprises a grip jaw consisting of a front roller and a front top roller; yard guide matched with the grip jaw; matched travellers, rings and bobbins. An entire fiber agglomeration plate is arranged between the grip jaw and the yard guide. The upper surface of the entire fiber agglomeration plate is provided with a plurality of entire fiber gathering grooves in the shape of 'v'. And the entire fiber gathering groove is utilized to control dissipation fibers of the spinning section which are incompletely twisted. A plurality of locating mounting holes are arranged at the entire fiber agglomeration plate, which are utilized to fix the entire fiber agglomeration plate. The ring spinning hairiness can be considerably reduced, and the ring spinning cloth can be maintained soft to wear when the hairiness reaches a compact spinning level at the same time. The control device for the yarn hairiness of the ring spinning frame has the advantages of being simple in structure, convenient in installation and wide in application range.

Description

technical field [0001] The invention relates to a special control device for a ring spinning frame, in particular to a yarn forming hairiness control device for a ring spinning frame. Background technique [0002] In the world, the ring spinning technology has stable yarn quality and soft cloth surface. It is the most commonly used spun yarn spinning method so far. During the twisting process, a large number of fibers outside the twisting triangle area escape to form hairiness. Harmful hairiness of more than 3mm will have many adverse effects on the fabric feel and subsequent processing, such as unclear fabric texture and unclear weaving opening, resulting in a decrease in efficiency. etc. [0003] Aiming at the problem of high hairiness in ring spinning, sizing operation is usually carried out in subsequent weaving to conform to the hairiness and facilitate weaving. Yarns with more prominent hairiness problems have higher sizing costs; singeing can also be used to deal wit...

AI Technical Summary

Problems solved by technology

Among the many explorations to solve the hairiness of ring spinning, only the negative pressure compact spinning based on ring spinning can effectively control the size of the twisting triangle, thereby greatly reducing the hairiness without damaging the evenness and strength. The problem is that the cloth surface feels hard, and the wearing performance is reduced. At the same time, the cost of purchasing or modifying the host machine and the post-operation cost of compact spinning are at a relatively high level.
