Problems solved by technology

[0004] The traditional discharge dyeing method is to dye the fabric and then pull it out. The background color of the discharge dyeing and the coloring in the color discharge are both a single color, without the multi-color effect of colored spinning. The background color of the white discharge is white, and the color discharge The color is also a single color
At present, the dyed yarn produced by the traditional process cannot be discharged and printed

Embodiment 1

[0024] Example 1: Removable Cotton Loose Fiber Dyeing

[0025] Choose 160 kilograms of cotton sliver loose fibers for use, put it into a solution with a bath ratio of 1:8 and 12 g / liter of chelating dispersant CT powder (soft water effect) at room temperature, add penetrating agent JFC 2%, scouring agent SA 0.5% Keep warm at 60°C for 20 minutes, let off the corner water, use discharge dyeing black K-GR with 5% removable dye, dye with conventional cotton loose fibers, wash with water, add 0.5% acetic acid to neutralize at 60°C to pH 6-7, add RS Soaping powder 1.5% heat up to 95°C for soaping for 10 minutes, after hot washing with water, add soft oil SL-92% at 60°C for 20 minutes.

Embodiment 2

[0026] Embodiment 2: Dyeing of loose fiber of pulling resistance

[0027] First, the dye is reduced in a dry vat. The dye formula is vat green 1.7% vat yellow 0.3%, caustic soda 30% 25g / L is added to the auxiliary vat of the dye vat, the concentration of the chemical is 1%, start stirring, heat up to 60°C, add insurance Powder 16g / L, keep warm for 150-20 minutes, fully reduce, and carry out pretreatment of cotton while reducing the dye drying tank, add penetrating agent JFC 2%, scouring agent SA0.5%, keep warm at 60°C for 20 minutes, let go Water, adjust the bath ratio 1:15, raise the temperature to 60°C, add the remaining 4g / L of hydrosulfite, add 1% Pingping O as a dye retarder, keep warm for 5 minutes, add the reduced dye, and keep warm for 30-60 minutes , After letting go of the horny water, oxidize in air, add 0.5% acetic acid at 60°C to neutralize to pH 6~7, add 1.5% RS soaping powder and heat up to 95°C for soaping for 10 minutes, after hot washing with water, add soft ...

Embodiment 3

[0028] Embodiment 3: pull out white

[0029] 95% of white cotton and 5% of extractable black colored cotton (production in Example 1) are woven according to the color spinning production process, and the whitening pulp is prepared and added with 20% carved white block, whitening agent MST 0.5% for cotton, urea 4%, 4% glycerin, 10% white paint, add 15% paste CMSF-10, perform whitening according to the required printing process, steam at 102°C for 12 minutes, wash in cold water, soap in boiling water, and dry.

Abstract

The present invention belongs to the field of discharge dyeing technology for fiber dyed fabric. The discharge dyeing process for fiber dyed fabric includes the following steps: 1. dyeing fiber with active dye or vat dye; 2. spinning with dyed fiber and primary color fiber; 3. weaving with the dyed fiber yarn; and 4. discharging the color of the fiber dyed fabric. The present invention provides novel diversified discharge dyed fiber dyed fabric.

Description

technical field [0001] The invention belongs to the technical field of discharge dyeing methods for colored textiles. Background technique [0002] Discharge printing refers to the process of partially eliminating the original white or colored patterns on dyed fabrics by printing methods. The color dyed on the fabric is called ground color. Chemicals that remove ground color are called dye discharge agents. In discharge printing, the printing paste containing discharge agent is first printed on the ground color, and after drying, it is steamed, and the ground color dye is decomposed and can be washed and removed. The process of obtaining a white pattern on the ground color with a printing paste containing only a discharge agent is called white discharge printing; adding to the discharge printing paste is not affected by the discharge agent and can be steamed in the process of decomposing the ground color dye At the same time, the process of dyeing the dyes on the fibers a...
