Pretreating equipment for improving yarn sizing performance

Abstract

The present invention relates to a pretreatment equipment capable of on-line improving yarn sizing performance for sizing machine. Said pretreatment equipment can be mounted between the warping beam frame of sizing machine and size box, and is formed from the following several portions: box body, guiding roller, high-voltage discharge heads, ozonator, UV irradiation device and sealing rubber-covered roll. Said invention also provides the working principle of said pretreatment equipment and its operation method.

Description

technical field [0001] The invention relates to a pretreatment device used on a sizing machine to improve yarn sizing performance on-line, which belongs to textile machinery equipment. Background technique [0002] Sizing is an important process in the weaving industry. Although it is only a preparatory process, good sizing can greatly reduce warp breakage in the weaving process, and a good desizing process is conducive to the smooth progress of dyeing. Therefore The factory generally concludes that "sizing the yarn will solve 70% of the weaving problems", which can explain the importance of the sizing preparation process. From the point of view of the matching equipment of the weaving department, one sizing machine needs to supply about 300 looms. From the perspective of production, one minute of sizing production takes one shift of looms. Therefore, the quality of sizing has a great impact on weaving. Process to achieve high yield, high quality, low consumption has a very...

AI Technical Summary

Problems solved by technology

This leads to the deterioration of its water solubility, and it even needs to be boiled at high temperature for 2-3 hours to dissolve, which not only consumes a lot of energy during the cooking process, but also brings great difficulties to the pulping equipment of textile mills

2. Warp yarn sizing, gray fabric desizing, and PVA bring great difficulties to the pre-treatment of printing and dyeing factories

3. Difficult to degrade and affect the environment

4. The price is relatively expensive. The price of ordinary PVA is about 13,000 yuan, which is much higher than that of starch paste.

However, no matter what kind of alternative products, it is only a partial replacement, and it is not easy to replace them completely. Moreover, these alternative slurries will also produce new pollution during processing, and the processing and use costs are relatively high.
