Desizing Enzyme

 Definition of desizing enzyme

Desizing enzymes, is a compound using of microbial fermentation of starch enzymes and other effective substances. Applied in the textile industry, it helps to decompose the starch in the fabric size into short chain dextrin and oligosaccharide, and make it extremely easy to remove in the latter treatment process. Desizing enzymes can be used in cotton, silk, Vinylon, viscose fiber, blended fabric, yarn-dyed poplin and chemical fiber blended fabric.

 

Desizing process in textile

In the weaving process, the fibers need sizing to increase fastness. In the fabric dyeing, bleaching and printing processes, it’s required to remove the size. Desizing is good or bad, directly affect the quality of finished products, such as hand feeling, whiteness, smoothness, color content and strength. Now mostly using starch paste for sizing, and a lot of methods for desizing, such as caustic soda, sulfuric acid, hydrogen peroxide, etc., but these chemical products not only damage the fabric, trouble operation, but also pollute the environment. Thus using the desizing chemicals in certain conditions, starch pulp can quickly become dextrin, after liquefaction of soluble dextrin washed with washing, so as to achieve the purpose of desizing.

Advantages of desizing enzyme

Desizing enzyme has many advantages, which are adopted by more and more textile factories, especially some advanced fabrics having no other choice but desizing enzyme. In the whole textile market home and aboard, desizing enzyme process accounted for a large proportion. Its characteristics are: high efficiency and high speed, suitable for high temperature desizing, short time, desizing rate of up to 90%- 95%; fabric no damage, soft hand feeling after desizing, full and strong finish, bright color; desizing and color fixing can be treated with the same bath, thus to shorten process flow and improve labor productivity; used for whiteness, it, can improve the capillary effect, and improve the production conditions, save fuel, reduce cost, and can be used for continuous large production.

The General Steps for Examining the Quality of The Appearance of Textile

The contents for examining To examine the quality of the appearance of textile starts from the accuracy of colors The inspection process is as follows: to test the accuracy of color; raw materials, weaving defects, defect inspection and defect treatment before dyeing defect and finishing defects, in accordance with the standard requirements to determine whether to cut off or drop size. When the color accuracy test is in dispute, the dispute can be settled down according to the measurement results of the electronic color matching system. 1) Material defects The raw materials have obvious defects like big belly yarn evenness is not uniform, there are too many joints, yarn, fiber, silk, specific bad Spandex Covered Yarn Quality, blended yarn uneven mixing and so on, which are likely to cause the fabric etc.. 2) Weaving defects Weaving defects come from many aspects, such as equipment itself, raw materials, environment, temperature and humidity, operator technical level, fabric structu...
