Embodiment 1

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

[0036] Fill soft water in four washing tanks of rewashing equipment, the water temperature of the second washing tank is 85 ℃, the water temperature of the third washing tank is room temperature, and the water temperature of other two washing tanks is 40 ℃. Add in-situ mineralization aid SZK to the first wash tank to make its initial concentration 10g / l, add in-situ mineralization aid SZH to the second wash tank to make its initial concentration 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 whole rewashing process, by controlling the flow rate of the pneumatic membrane pump, The additive concentration in the washing tank is kept constant by means of continuous and controllable addition. The dyed wool tops are guided by guide rollers, enter the rewashin...

Embodiment 2

[0040] This example provides a kind of rewashing processing method of dyed polyester fiber wool top, implements as follows:

[0041] Fill soft water in four washing tanks of rewashing equipment, the water temperature of the second washing tank is 80 ℃, the water temperature of the third washing tank is room temperature, and the water temperature of other two washing tanks is 45 ℃. Add in-situ mineralization aid SZK to the first washing tank to make its initial concentration 15g / l, and add in-situ mineralization aid SZH to the second washing tank to make its initial concentration 70g / l, Do not add any additives in the third washing tank; add 15g / l antistatic agent and 5g / l and crude oil in the fourth washing tank, and control the flow rate of the pneumatic membrane pump during the whole rewashing process. The additive concentration in the washing tank is kept constant by means of continuous and controllable addition. The polyester fiber wool top after dyeing is guided by guide...

Embodiment 3

[0045] This example provides a kind of rewashing processing method of dyed viscose wool top, implements as follows:

[0046] Fill soft water in four washing tanks of rewashing equipment, the water temperature of the second washing tank is 90 ℃, the water temperature of the third washing tank is room temperature, and the water temperature of other two washing tanks is 50 ℃. Add in-situ mineralization aid SZK to the first washing tank to make its initial concentration 20g / l, add in-situ mineralization aid 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 whole rewashing process, the flow rate of the pneumatic membrane pump is controlled to continuously The controllable addition method keeps the concentration of additives in the washing tank constant. The dyed viscose top is guided by guide rollers, enters the rewa...

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...
