Problems solved by technology

S-type reactive dyes contain two active groups of vinyl sulfone and chloro-s-triazine. The dye has strong reactivity, high color fixation rate, bright color, excellent dyeing fastness to washing and rubbing fastness; the first disadvantage is the light fastness of the dye Poor, can only reach 3~4 grades, some colors, such as blue gray, light fastness is only 2~3 grades; second, the compatibility of dyes is not good, the synchronization of dyeing and dyeing is poor, there is a color difference between the head and the tail of the jigger dyeing, the cylinder head More cylinder tail cutting heads
The influence of these two factors restricts the product quality

Abstract

The invention discloses a pure-cotton double-layer jacquard home textile dyeing and finishing method, and belongs to the technical field of pure-cotton fabric dyeing. The method is characterized by comprising the following preparation steps: with a dyeing liquid formula, namely an active dye with two active groups of ethylene sulfuryl and hydroxyl ethylene sulfone sulfate in a main liquid, putting20-50% in percentage by mass of a dye liquid into a dyeing tank, and performing dyeing once; adding the rest dyeing liquid, and performing dyeing once again; adding sodium sulfate, and performing dyeing once; adding alkali powder, and performing dyeing once; adding a soaping agent SN-45, increasing the temperature, and performing dyeing for three times; washing with cold water, adding a neutralization acid, and performing dyeing for three times; performing acid pickling, and discharging a fabric roll. The inventor improves a cotton double-layer jacquard fabric dyeing process, and together with the selected active dye with two active groups of ethylene sulfuryl and hydroxyl ethylene sulfone sulfate in the main liquid, factors such as the soaping fastness, the lifting power of the dye, thedyeing velocity and the curve of the dye, the matching property of the dye, and the like are improved.

Description

technical field [0001] The invention discloses a method for dyeing and finishing pure cotton double-layer jacquard home textiles, which belongs to the technical field of pure cotton fabric dyeing. Background technique [0002] Among the four natural fibers "cotton, silk, wool, and linen", cotton fibers have the largest number, the most widely used, and the most closely related to people's lives. Cotton fiber is a porous substance, and there are many hydrophilic groups (-OH) on its cellulose macromolecule, so its hygroscopicity is good. Under normal atmospheric conditions, the moisture regain of cotton fiber can reach about 8.5%. Therefore, cotton fiber has the characteristics of moisture absorption and perspiration, refreshing and skin-friendly, and is widely used in the production of clothing fabrics and bedding sets. [0003] Pure cotton double-layer jacquard fabric, weave specification A layer 40s*(12s+10s / 2) 173*80 B layer 60s*(21s+12s / 2) 173*90, special double-layer st...
