Device for reducing yarn hairiness

Abstract

The invention discloses a device for reducing yarn hairiness, which is arranged between a front roller nip and a yarn guide hook of a spinning frame. The device mainly comprises a dried glue plate, a hydraulic device and a recovery bottle. The device can be applied to technological improvement on the spinning frame, the dried glue plate is arranged on a vehicle table support and dry glue is used for forming yarn, so that the yarn hairiness is reduced, and a layer of protective film is formed outside the yarn. Compared with other prior arts, the device is high in cost performance, and is simple and convenient to install.

Description

technical field [0001] The invention relates to the new technology field of short fiber spinning, and in particular relates to a device installed downstream of a drafting device of a ring spinning frame to achieve the purpose of reducing yarn hairiness by shaping the fibers. Background technique [0002] Hairiness is an important quality indicator affecting yarn appearance and style. The uneven distribution of hairiness on the yarn and the formation of new neps during weaving will affect the appearance quality of dyed fabrics, and some will form crossbar defects. When the air-jet loom produces high-density fabrics, when the hairiness on the weft yarn is too much, the diameter of the weft yarn will increase, resulting in difficulty in weft insertion. When the hairiness of the warp yarn is too much, the adjacent warp yarns will be entangled, resulting in unclear openings, resulting in weaving defects and affecting the product. quality. In the following processes, the hairine...

Problems solved by technology

When the air-jet loom produces high-density fabrics, when the hairiness on the weft yarn is too much, the diameter of the weft yarn will increase, resulting in difficulty in weft insertion. When the hairiness of the warp yarn is too much, the adjacent warp yarns will be entangled, resulting in unclear openings, resulting in weaving defects and affecting the product. quality

In the following processes, the hairiness on the yarn will fall off due to friction, forming flying flowers to pollute the environment, endangering human health, and new defects will also be produced to reduce the quality of yarn and fabric

Ring spinning is the most commonly used spinning form in spinning production at present, but there are still some problems in the development of ring spinning, especially the yarn surface hairiness caused by the spinning process, which is difficult for the processing of subsequent processes, The physical and mechanical properties of the yarn and the quality of the fabric have a greater impact

[0003] The problem of yarn hairiness has long attracted the attention of the textile industry at home and abroad, and many methods have been used to control hairiness, such as the use of compact spinning technology, which eliminates the spinning triangle area, shrinks and draws the strands and twists them, thereby reducing hairiness, but the transformation of compact spinning technology High cost, high energy consumption, and inconvenient management
