Problems solved by technology

However, the light and oxidation fastness of medium and light colors produced by it is extremely poor, and the PH value of the cloth surface has a great influence on the color and light, especially khaki, coffee, and army green.
The more fatal disadvantage is that the products produced by this process are seriously not resistant to chlorine bleaching, which is worse than reactive dyeing
The wet and dry rubbing fas

Embodiment 1

[0011] The process of the reduction, washing and fading dyeing process of the present invention is as follows: semi-finished white cloth → padding dyeing solution process → first drying process → padding reducing solution process → steaming process → water washing process → oxidation process → soaping process → Washing process → second drying process → padding softening process → tentering process → pre-shrinking process → finished product.

[0012] Among them, steaming process, water washing process, oxidation process, soaping process, water washing process, second drying process, padding and softening process, tentering process and pre-shrinking process are conventional processing processes in this industry.

[0013] in:

[0014] Padding dyeing process: according to the color of the fabric to be dyed, add a corresponding amount of dye in the water bath, pad at room temperature, and the speed is 30 m / min. The dye used is a mixture of vat dyes and sulfur dyes in a weight rati...

Abstract

The invention discloses a dyeing processing using reducing and bleeding, which is realized by the following scheme: obtaining semi-finished product of plain white cloth, and working procedures of padding dye solution, steaming, washing, oxidizing, soaping, washing, drying, padding and softening, tentering, shrinking and obtaining a finished product. Another drying working procedure and the working procedure of padding reducing solution are sequentially added between the working procedures of padding dye solution and the steaming; and dye used by the working procedure of padding dye solution is a mixture of reducing dye the weight ratio of which is 2:3-3:2 and sulfur dye. By the invention, the reducing dye with excellent color fastness and sulfur dye which is easy to bleed are mixed and compounded according to a certain proportion to obtain new bleeding and reducing dye; and two kinds of dye can be simultaneously dyed on the cloth cover by adding a reducing agent suitable for the sulfur dye in a reducing solution prescription and using a one-step dyeing method. Compared with the prior art, clothes made of fabrics dyed by the process can obtain satisfied bleeding, traditional and leisure style after being subject to simple washing with enzyme; and in addition, the light fastness in the medium-light colors can reach 3-4 levels.

Description

technical field [0001] The invention relates to the field of textile dyeing and finishing, in particular to a wash-out dyeing process. Background technique [0002] The current wash-out dyeing continuous pad dyeing process mainly includes paint dyeing process and sulfur dye dyeing process. [0003] The technological process of paint dyeing process is: semi-finished white cloth→padding paint process→dyeing process→drying process→baking process→padding softening process→stenter process→pre-shrinking process→finished product. The paint dyeing process has the characteristics of low price and complete chromatogram, but it has poor dry and wet rubbing fastness, especially the particularly poor scrubbing fastness. After scrubbing or scrubbing, the finished garment will cause partial whitening, and the light color fastness to light is poor. Since the paint is covered by an adhesive film on the cloth surface, the hand feel will also be affected, and the fluctuation of the setting te...
