Problems solved by technology

If the amount of alkali used in this method is improper, it is easy to cause certain damage to the silk fabric.
The enzymatic desizing method has a good effect on removing starch size, and the desizing time is short, but it is less effective in removing natural impurities in silk fabrics
Oxidant desizing method has fast desizing speed and good effect, but more materials are used and the cost is higher

Abstract

The invention discloses a desizing process of silk fabric. The desizing process comprises the following steps: performing plasma treatment on a to-be-processed silk fabric, padding-rolling the treated silk fabric in warm water, taking out the silk fabric, padding-rolling desizing liquid, piling; warming the desizing liquid to 90-120 DEG.C, steaming for 10-30min by keeping temperature, taking out the silk fabric, washing for 2-4 times by using hot water, washing for 1-3 times by using cold water, taking out and airing to obtain the desized silk fabric. The silk fabric desized through the process disclosed by the invention can be easily dyed and finished, the damage to the silk fabric is small, the desizing process is simple, and the cost is low.

Description

Technical field: [0001] The invention relates to a dyeing and finishing process of silk fabrics, in particular to a desizing process of silk fabrics. Background technique: [0002] When weaving in textile mills, in order to reduce warp breakage and improve weaving efficiency, silk fabrics are generally subjected to sizing treatment, thereby enhancing the strength and wear resistance of silk fabrics. The sizing rate is generally controlled at 4-8%. The sizing of silk fabrics is beneficial to weaving, but it brings great troubles to the dyeing and finishing process. Therefore, the first process of the dyeing and finishing process is to find a way to remove the size. At present, the main methods of desizing are alkali desizing method, enzyme desizing method and oxidant desizing method. [0003] The alkali desizing method is mainly used for silk fabrics that are sized with chemical sizing (PVA, etc.) or mixed with other sizing materials, and used for silk fabrics that are main...
