Desizing equipment for spinning fabric

Abstract

The invention mainly discloses a desizing equipment for textile fabrics. Its technical proposal includes a cloth laying rack, a pretreatment device, a scraping device and a desizing box. The pretreatment device includes a pretreatment rack, a water receiving tank, and a transmission roller. And the water spray device, the water receiving tank is located at the bottom of the pretreatment frame, the transmission rollers are distributed on the pretreatment frame in an inverted triangle, the water spray device is located between the adjacent transmission rollers, the scraping device includes a scraping box, the first cloth guide roller , brushing roller and driving device, the driving device respectively drives the first cloth guide roller and brushing roller to rotate, the desizing box includes a trough and an oscillating trough, and a feeding device and a second cloth guide with a heating pipe are arranged in the trough The roller has an oscillating device in the oscillating groove, and the oscillating device includes an oscillating roller, an oscillating wheel and an oscillating motor. The invention has fast desizing speed, high desizing efficiency, less damage to fabric fibers, removes pollutants and symbiotic impurities on fabrics, and is convenient for later processing of fabrics.

Description

technical field [0001] The invention relates to a desizing device for textile cloth. Background technique [0002] In the prior art, the warp yarns of fabrics such as cotton, viscose, and synthetic fibers have reduced strength. During the weaving process, the warp yarns are subject to relatively large tension and friction, and are prone to breakage. In order to reduce warp breakage and improve weaving efficiency and gray fabric quality, it is necessary to sizing the warp yarn before weaving to make the yarn compact and smooth, thereby improving the breaking strength and wear resistance of the yarn. Sizing is beneficial to weaving, but it brings difficulties to the subsequent dyeing and finishing process. The sizing on the gray cloth will pollute the working fluid, hinder the penetration of dyes into the fiber, and affect the wettability of the fabric. Therefore, in the finishing process, the fabric needs to be desized first. Desizing is to swell or cut the high-molecular-w...

AI Technical Summary

Problems solved by technology

In the desizing process of the fabric, the fabric is generally put into the trough to heat and absorb the material, and then the fabric is washed and dried to complete the desizing process. The steps of this method are relatively simple, and the desizing effect is not good. The contact between the desizing material and the fabric is uneven and incomplete, the desizing efficiency is low, and the size will still adhere to the fabric after washing
