Example Embodiment

[0034] Example 1

[0035] This example provides a method for rewashing dyed wool tops, which is implemented as follows:

[0036] Fill the four washing tanks of the rewashing equipment with soft water. The water temperature of the second washing tank is 85°C, the water temperature of the third washing tank is room temperature, and the water temperature of the other two washing tanks are both 40°C. Add the in-situ mineralization assistant SZK to the first washing tank to make the initial concentration of 10g / l, and add the in-situ mineralization assistant SZH to the second washing tank to make the initial concentration of 60g / l, No additives are added to the third washing tank; 5g / l antistatic agent and 20g / l and crude oil are added to the fourth washing tank. During the entire rewashing process, by controlling the flow of the pneumatic membrane pump, With continuous and controllable addition, the concentration of the auxiliary agent in the washing tank is kept constant. The dyed w...

[0044] Example 3

[0045] This example provides a method for rewashing dyed viscose tops, which is implemented as follows:

[0046] Fill the four washing tanks of the rewashing equipment with soft water. The water temperature of the second washing tank is 90°C, the water temperature of the third washing tank is room temperature, and the water temperature of the other two washing tanks are both 50°C. Add in-situ mineralization assistant SZK to the first washing tank to make its initial concentration 20g / l, and add in-situ mineralization assistant SZH to the second washing tank to make its initial concentration 80g / l, No additives are added to the third washing tank; 25g / l antistatic agent and 20g / l silicone oil are added to the fourth washing tank. During the entire rewashing process, the flow rate of the pneumatic membrane pump is controlled to continuously The controllable adding method keeps the concentration of additives in the washing tank constant. The dyed viscose top is gu...

Abstract

The invention relates to in-situ mineralization auxiliary agents SZK and SZH and after backwashing method used in dyed slubbing after backwashing. The auxiliary agent SZK is composed of 0.001 to 10% of sulfamic acid, 0.001 to 5% of polyacrylic acid, 0.001 to 3% of potassium chloride, 0.001 to 3% of copper sulphate, and the balance water; and the auxiliary agent SZH is composed of 5 to 15% of potassium permanganate, 1 to 5% of carboxymethyl cellulose, 1 to 10% of anhydrous sodium sulfate, and the balance water. According to the after backwashing method, dyed slubbing is delivered though after backwashing bath containing the auxiliary agent SZK and after backwashing bath containing the auxiliary agent SZH successively for washing, wherein water bath temperature and concentration, and slubbing moving speed are controlled. In-situ mineralization is adopted in after backwashing process, so that advanced water-saving and emission reduction are realized; operation requirements are low; operation is simple; and popularization is convenient to realize.

Description

technical field [0001] The invention belongs to the technical field of textile dyeing and finishing, and in particular relates to a post-dyeing treatment auxiliary agent capable of removing residual dyes and a rewashing method after dyeing. Background technique [0002] In the process of worsted fabric processing, the fiber tops must be rewashed after being dyed. One of the main purposes is to remove residual dyes and other organic impurities on the dyed fibers. In the general rewashing process, the dyed fiber is continuously passed through several rewashing tanks containing detergent or other conditioning agents in the form of wool strips, and the organic impurities on the fibers are removed by liquid flow circulation and roller pressing, and the fibers are processed. conditioning. After the organic impurities on the fibers enter the rewashing tank, the organic impurities in the cleaning water will continue to increase. In order to ensure the effect of rewashing, waste wat...
