Abstract

A cellulose fiber garment anhydrous salt-free dyeing method includes the steps: 1) preparation of a modification solution, 2) padding and drying, 3) preparation of a dyeing solution, and 4) garment dyeing and padding. Compared with traditional garment dyeing, the cellulose fiber anhydrous salt-free garment dyeing has unique process characteristics, especially preparation of the modification solution in the garment dyeing; in addition, in the knitted fabric anhydrous salt-free garment dyeing process, in fabric padding, the caterpillar band speed and considered reasonable control of the tension, compared with a commonly used dip dyeing process of cotton knitted fabric dyeing, the anhydrous salt-free garment dyeing can substantially reduce the consumption of water, heat and chemicals in the dyeing process, and has huge advantages in energy conservation, emissions reduction, consumption reduction and cost reduction.

Description

technical field [0001] The invention relates to the field of garment dyeing and finishing, in particular to a water-free and salt-free dyeing method for cellulose fiber garments. Background technique [0002] Cellulose fiber dyeing is a process of dyeing cotton, hemp and other fiber textiles. Cotton and hemp fiber fabrics need to fully remove cellulose symbiosis before dyeing, minimize tension and friction during dyeing, and prevent deformation or fluff from affecting the quality of dyed products. The dyes used in cellulose fiber dyeing mainly include direct dyes, reactive dyes, insoluble azo dyes, temporarily soluble vat dyes, vat dyes and sulfur dyes. Reactive dyes are widely used due to their excellent dyeing properties, but the use of a large amount of inorganic salts in the dyeing process to improve the dye uptake rate and color fixation rate has brought environmental pollution. Cotton fiber cationization is one of the more direct and effective ways to solve the dyein...
