Embodiment 1

[0044] Ready-made garments made of semi-bleached fabric; specification: 40×40 / 133×72; composition: 100% cotton.

[0045] The above-mentioned garments are put into the garment dyeing machine, and the following procedures are carried out in sequence:

[0046] Pretreatment process

[0047] Add pretreatment working reagents to the garment dyeing machine at room temperature, raise the temperature to 95°C at a heating rate of 2°C / min, and react for 15 minutes; cool down to 85°C at a cooling rate of 2°C / min, wash with water at 85°C for 5 minutes; add glacial acetic acid Adjust the pH value to 6.5; wash with water at room temperature for 10 minutes;

[0048] The pretreatment working reagents include:

[0049] Soda ash 4g / L;

[0050] Transfar refining agent TF-1085g / L.

[0051] The g / L is the number of grams of each component of the working reagent added to the liquid in the garment dyeing machine per liter (the same below).

[0052] dyeing process

[0053] Add dyeing reagents to...

Abstract

The invention discloses a one-bath garment dyeing technology of a reduced dye and a water-soluble sulfur dye. The one-bath garment dyeing technology comprises a pre-treatment procedure, a dyeing procedure, a soaping procedure, a sodium hypochlorite washing procedure and a cellulase enzyme washing procedure, which are sequentially carried out on a to-be-dyed garment, wherein a dyeing work reagent used in the dyeing procedure comprises the following components in percentage by weight: 1%-5% of the water-soluble sulfur dye and 0.5%-4% of the reduced dye. The nostalgic style of traditional garment dyeing is reserved by the dyed garment; compared with a traditional garment dyeing product, the physical indexes of the light fastness, the rubbing fastness and the like of the product disclosed by the invention are greatly improved; the garment produced by the technology can be further intensively processed; and the one-bath garment dyeing technology is especially applicable to the dyeing and processing requirements of various garment production and dyeing factories on clothes.

Description

technical field [0001] The invention relates to the technical field of dyeing and finishing in the textile manufacturing industry, in particular to a garment dyeing process of vat dyes and water-soluble sulfur dyes in the same bath. Background technique [0002] Garment dyeing is valued by people because of its small batch, multiple varieties, special retro effect, not only the style of denim, but also its diversified colors better than denim to meet the changing needs of the market. However, there are certain disadvantages in the garment dyeing process currently on the market, such as poor color fastness to sunlight and rubbing. Adopt the dyeing method that fastness is good, the vintage imitation old feature of garment dyeing is not obvious, not attractive in appearance; There is not a kind of garment dyeing process that can take into account the attractive in appearance of color and color fastness well. Contents of the invention [0003] The purpose of the present inve...
