Problems solved by technology

[0003] Alkali treatment is usually used for desizing and scouring of cotton fabrics, but this treatment method will generate a large amount of alkaline wastewater and cause adverse effects on the environment; the emerging biological enzyme method on the market has the advantages of rapid response, environmental protection and effectiveness , but at the same time, biological enzymes have strong specificity and cannot effectively remove all the components that need to be removed from cotton fabrics

Embodiment Construction

[0009] The specific implementation of the present invention will be further described below in conjunction with the examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0010] The technical scheme of concrete implementation of the present invention is:

[0011] A pre-treatment process for printing and dyeing of cotton fabrics, including raw fabric preparation, singeing, desizing, scouring, bleaching, and mercerizing; wherein, the desizing and scouring are carried out by combining biological enzymes with sodium hydroxide, and the specific steps are:

[0012] 1) Desizing treatment: use amylase impregnation method, the bath ratio is 1:20, add amylase with a concentration of 3-5g / L, and penetrant JFC with a concentration of 0.5-2g / L, adjust the pH to 6-7, and the temperature is 60-70℃, soaking time is 60min, and then wash with water for 5min;

Abstract

The invention discloses a printing and dyeing pre-treatment process of cotton fabric. The process comprises preparation of raw cloth, singeing, desizing, scouring, bleaching and mercerization, wherein desizing and scouring are performed in a bio-enzyme and sodium hydroxide combination manner. The printing and dyeing pre-treatment process of the cotton fabric has a good treatment effect and is safe and environment-friendly.

Description

technical field [0001] The invention relates to a pretreatment process for printing and dyeing, in particular to a pretreatment process for printing and dyeing cotton fabrics. Background technique [0002] The warp yarns of cotton fabrics are mostly sizing before weaving to improve the strength, abrasion resistance and smoothness of the warp yarns. The size will affect the wettability of the fabric during the dyeing and finishing process and hinder the contact of chemicals to the fibers. Therefore, the fabric is generally desized before dyeing and finishing. Cotton fiber companions, cotton seed hulls and residual size after desizing must be removed by scouring to obtain good wettability and appearance of the fabric. [0003] Alkali treatment is usually used for desizing and scouring of cotton fabrics, but this treatment method will generate a large amount of alkaline wastewater and cause adverse effects on the environment; the emerging biological enzyme method on the market...
