Dyeing method of cloth

Abstract

The invention relates to a dyeing method of cloth, which is realize through the following steps of: preparing one ton of gray cloth; then piping; trimming the cloth; then entering a cold pad machine for cold pad treatment; carrying out the cold pad treatment for 8-10 minutes, and then stacking in a cloth trolley; striking by using a plastic bag, and stacking at the constant temperature of 26-28 DEG C for 12 hours; then starting to dye for about 3 hours; cleaning, cutting plates and checking colors after two hours; then washing fastness by needing three vats of water; and carrying out the softening treatment in the cold pad machine for 8-10 minutes. The invention has short vat occupying time and can enhance the utilization rate of the vats and increases one vat 24 hours a day.

Description

technical field [0001] The invention relates to a dyeing method, in particular to a cloth dyeing method. Background technique [0002] The dyeing of cloth in the prior art is generally realized through the following steps: [0003] First, the gray cloth is prepared, then the edge is overlaid, the cloth is straightened, and then the bottom is floated in the tank; the bottom float takes 2.5 hours, taking 1 ton of cloth as an example, the first time requires 12 tons of water and the proportion of hydrogen peroxide is 5%-6%, soda ash 1.2%, 1.5% refining agent, 1%-2% anti-wrinkle agent, 1%-2% degreaser and other additives; it needs to be heated at 98°C for 60 minutes; for the second wash, clean 12 tons of water, 60 ℃; the third acid treatment, PH value test 60 ℃ 12 tons of water; after the fourth washing, hot water bubbles, 98 ℃ water 12 tons; [0004] Then start dyeing; it takes about 3 hours, add dye, heat up to 60°C, add soda ash and leveling agent; [0005] After 2 hours, ...

Problems solved by technology

[0008] In the above steps, high-temperature oxygen bleaching must be carried out to remove grease, cottonseed shells and other impurities on the surface of the gray cloth, in order to achieve the required coloring rate, smoothness of the gray cloth, and vividness of the color during dyeing; the disadvantage of conventional oxygen bleaching is that High temperature (98 degrees * 1 hour), the required amount of steam is large, and after the oxygen bleaching is completed, it is necessary to wash the remaining additives and impurities on the gray cloth with circulating water several times in a row, so that the gray cloth can meet the normal dyeing requirements. The water consumption is large; The surface finish after high temperature oxygen bleaching is rough

The texture of the gray cloth is poor, and the gray cloth (spliced ​​thread, twisted thread, OE, air-spun and other jersey cloth) that has undergone high-temperature oxygen bleaching has fine wrinkles (this is the most troublesome thing in the dyeing industry), and it must be occupied during oxygen bleaching. The dyeing vat time is about 2.5 hours, which is not conducive to increasing the dyeing output
