Process for cotton reactive dye applying in silk broadcloth dying

Abstract

The invention relates to a technique for dyeing silk fabrics by a cotton reactive dye. The technical problem to be solved is that the technique needs to dye silk fabrics by the cotton reactive dye effectively, has the characteristics that the dye uptake is high, the fixation ratio is high, the color depth of the product is increased greatly, the coloring matter is saved and the dyeing quality is high; moreover, the residual liquid discharge concentration is decreased and the environment is protected. The technical proposal is to adopt the cotton reactive dye for dyeing silk fabrics and has the following steps that: 1) the silk broadcloth after the pre-treatment is placed into a dye vat, a dye solution is prepared and is added into the dye vat to dye, the dye solution has a pH value ranging from 6.5 to 7.5, the dye temperature ranges from 85 to 98 DEG C, the dye time lasts one to two hours; 2) the dye residual solution is discharge partially or completely, clear water is added, the temperature is adjusted to 50 to 60 DEG C; 3) certain amount of ammonium polycarylate is added to fix the color, the pH value is kept to be 9 to 10, the fixation time lasts one to two hours, the temperature of the clear water ranges from 4 to 20 DEG C.

Description

technical field

[0001] The invention relates to a dyeing process of real silk, in particular to a process for dyeing satin, spinning and thick sand-washed real silk fabrics with reactive dyes for cotton. Background technique

[0002] .With the development of the silk printing and dyeing industry and the advancement of technology, the industry has begun to use reactive dyes to dye real silk; the dyeing mechanism is: a chemical reaction between the dye and the fiber eventually forms a covalent bond, which is achieved due to the firm covalent bond. The purpose of high color fastness of the product.

[0003] At present, there are still the following deficiencies in the dyeing of real silk with reactive dyes:

[0004] 1. Use reactive dyes for wool to dye real silk, adopt high temperature exhaust dyeing method, the temperature is about 95 ℃, and the pH value of the dyeing solution is 4-8. However, this kind of dyestuff has a low dyeing rate for real silk and cannot be dyed into ...

[0031] A. Pretreatment

[0032] Additives: silk hair oil: 2g / l, penetrating agent: 0.5g / l, six pieces: 2g / l

[0033] Before entering the vat, check whether the machine meets the production requirements, fill in the water according to the standard water level, and then enter the vat with a flat width. Pay attention to weft inclination; take 1 pass of cold water; add pre-treatment additives, the temperature rises to 95°C±2°C, take 4 passes of drainage, 1 pass of warm water at 40°C, 1 pass of cold water, and wait for dyeing.
