Embodiment 1

[0019] This embodiment is a method for dyeing and finishing pure cotton knitted fabrics with bright fluorescent yellow dyes, which has the following steps:

[0020] ① Pre-treatment: immerse the grey cloth in a bathtub filled with refining liquid, and refining at a temperature of 110°C for 30 minutes; the pH of the refining liquid is 11-12. The refined liquid contains 2g of softener, 4g of NaOH, and 8g of H per liter. 2 O 2 , 1g of refined penetrant, 0.5g of degreasing agent in water solution.

[0021] Among them, the softener is the FH cotton bath softener produced by Wuxi Yuda Fine Chemical Co., Ltd., and its main component is a mixture of higher fatty acids and polyols. The refined penetrant is refined penetrant A produced by Shanghai Deyi Industry and Trade Co., Ltd., and its main component is a mixture of fatty acid polyoxyethylene and fatty acid ester. The degreaser is a Scotol C-180 degreaser produced by Suzhou Weiming Chemical Industry Co., Ltd. It is a special non-ionic su...

Abstract

The invention discloses a method for fluorescent dyeing and finishing of cotton knitted fabrics. The value is 6~7; ② Dyeing: Dip the refined gray cloth into the dye vat filled with water-soluble dye solution, and then pickle the dyed cloth with an aqueous solution of glacial acetic acid until the pH value is 4~5; Soaping and color fixing; ③Finishing: After the dyed cloth is taken out of the dyeing vat, it is dipped in the setting liquid in the medicine tank of the setting machine and then shaped. The method of the invention can improve the brightness and color fastness of cotton fabrics, raise the fluorescent color fastness of pure cotton fabrics to level 4 or level 5, and reach certain depth and color fastness.

Description

Technical field [0001] The invention belongs to the field of textile printing and dyeing, and particularly relates to a fluorescent dyeing and finishing method of cotton knitted fabrics. Background technique [0002] Dyeing and finishing of cotton fabrics with reactive dyes can be divided into three processes according to the different types of reactive dyes selected. [0003] One is to use common type (or cold dye type) reactive dyes. Due to the chemical properties of this type of dyes are very active and the reaction ability is strong, so it can chemically react with the fiber and dye at low temperature (20~30℃). At the same time, it only needs to be dyed at low temperature and weak alkaline agent (pH=10.5). The color fixation is completed under the existing conditions, but the stability of the dye solution is poor. [0004] The second is to use thermosetting reactive dyes. Its chemical activity is low, the reaction ability is also poor, and the dye solution is relatively stable...
