Embodiment 2

[0076] A cold pad-batch dyeing method for textile fabrics, said method comprising three stages of immersion, stacking and washing;

[0077] The immersion stage includes cold pad batch pretreatment, semi-finished products and dyeing and padding steps:

[0078] The stacking stage includes rolling and stacking steps;

[0079] The water washing stage includes water washing, soap washing, water washing and drying steps.

[0080] The pretreatment of the cold pad batch includes the steps of padding with padding working liquid, coiling, stacking, washing with alkali steam and water, and drying. The washing with alkali steaming includes steaming (100°C, 2-4min), hot water washing and cold water washing.

[0081] When selecting (removing) the bleaching cold batch method (more than 20h at room temperature), the composition ratio (g / l) of the padding working solution of the cold pad batch pretreatment is: NaOH: 40; H 2 o 2 : 20; water glass: 3; chelating dispersant: 6 and scouring age...

Abstract

The invention discloses a cold rolling stack dying method of face fabric, comprising immerging, stacking and water washing. The immerging step comprises cold rolling stack pretreatment, obtaining half finished product and drying rolling. The stacking step comprises coiling and stacking. The water washing step comprises washing with water, washing soap, washing with water and drying. The inventive method has advanced and reasonable process, with stable quality, energy-saving and environment friend functions, while the invention has simple process, low cost, and high fixation yield, or the like.

Description

technical field [0001] The invention relates to a method for dyeing and finishing textile fabrics by using cold pad-batch dyeing, and belongs to the technical field of cold pad-batch dyeing production for energy saving and clean production in the printing and dyeing industry. Background technique [0002] In recent years, with the continuous improvement of the material and cultural living standards of the people, people have higher and higher requirements for the color and comfort of clothing. As a result, sales of solid-color fabrics have increased significantly. As a result, reactive dyes with the advantages of bright color, complete chromatogram, cheap price, simple process, good level dyeing, and good washing fastness have become the most widely used dyes in the printing and dyeing industry. But everything has two sides. The affinity of reactive dyes to cotton fibers is not high, and the dye uptake rate is lower than that of direct dyes and vat dyes. It increases the c...
