This process has been used for decades. The process is lengthy, time-consuming, and the operation is complicated and strict (PH value control is strict). If it is not in place, the polishing effect will not be achieved, and even the dyeing quality will be affected.
In particular, the current cellulase polishing treatment is usually carried out before or after dyeing, and the residual alkali components exuded from the fibers during the boiling and bleaching process are likely to cause pH fluctuations, resulting in instability in the deoxygenation process and poor treatment effects

Embodiment 1
[0016] In this example, the samples to be treated are T / C (TERYLENCE / COTTON, polyester cotton cloth), CVC (chief value of cotton, textiles with a cotton content above 65%), T / R (POLYESTER / RAYON, polyester / cotton sticky) knitted fabrics. The sample to be treated is dyed according to the following process: alkaline dyeing and washing (398 process)--(reduction cleaning)--polishing, dyeing activity in the same bath treatment--post-treatment.
[0017] Among them, the one-bath method of oxygen removal and polishing dyeing is as follows: adjust the temperature to 40-60°C, adjust the pH value to 5-7, add polishing enzyme 988, and its addition amount is 1.5% (mass percentage), and add dye after 0-15 minutes , after 30 minutes, add sodium sulfate, add soda ash after 20 minutes, keep warm for 60 minutes, and the dyeing bath ratio is 1:5; sodium sulfate is added in 2 times, adding 1 / 3 of the total mass for the first time, and adding 1 / 3 of the total mass for the second time 2 / 3 of the to...
Embodiment 2
[0019] In this embodiment, the sample to be treated is rayon knitted fabric. Dye the sample to be treated according to the following process: Auxiliary 398 --- run for 15 minutes --- add dye (30 minutes) --- run for 15 minutes --- divide into 2 times to add starch powder (30 minutes ) --- run for 20 minutes --- add soda ash in 2 times --- heat preservation time --- post-processing --- cloth --- apply softener.
[0020] Among them, the one-bath method of oxygen removal and polishing dyeing is as follows: adjust the temperature to 40-60°C, adjust the pH value to 5-7, add polishing enzyme 988, the amount of which is 2% (mass percentage), and add dye after 0-15 minutes , after 30 minutes, add sodium sulfate, add soda ash after 20 minutes, keep warm for 60 minutes, and the dyeing bath ratio is 1:20; sodium sulfate is added in 2 times, adding 1 / 3 of the total mass for the first time, and adding 1 / 3 of the total mass for the second time 2 / 3 of the total mass; soda ash is added in 2 ...

Abstract
The invention discloses deoxidizing and polishing one-bath process dyeing of a polyester cotton knitted fabric and belongs to the technical field of dyeing or printing of textiles. The deoxidizing and polishing one-bath process dyeing of the polyester cotton knitted fabric comprises the following steps of: adjusting temperature to 40-60 DEG C; adjusting a PH value to 5-7; adding 1%-2% of polishing enzyme 988, adding dyes and dyeing assistants after 0-15 minutes, adding sodium sulphate after 30 minutes, adding sodium carbonate after 20 minutes; keeping the temperature for 60 minutes, wherein the polishing enzyme 988 is cellulose bio-enzyme and the addition amount is 1%-2%; the dyeing assistants are scouring and dyeing one-bath agents and are added in two steps with the total addition amount of 1%-2%; the dye bath ratio is 1:5-1:20, and assistant scouring and bleaching, dispersing alkali one-bath dyeing of polyesters and reduction clearing need to be sequentially carried out before the deoxidizing and polishing one-bath process dyeing. By adoption of the technical scheme, the polishing effect which is same to or better than that of separated-bath processing can be achieved; processed cotton fabrics have the advantages of less surface fuzz, clear textures and enhanced anti-pilling level; and dyeing coloured light and depth can not be influenced.
Description
technical field [0001] The invention relates to one-bath dyeing of polyester-cotton knitted fabrics by deoxidizing and polishing, and belongs to the technical field of dyeing or printing of textiles. Background technique [0002] The traditional fabric polishing process is boiling and bleaching→draining→hot water→peracid neutralization→washing→deoxidation→dyeing→post-treatment, that is, the fabric is pre-treated first, then the hydrogen peroxide residue is removed, and then the polishing process is performed. Final dyeing and post-processing. This process has been used for decades. The process is lengthy, seriously time-consuming, and the operation is complicated and strict (PH value control is strict). If it is not in place, the polishing effect will not be achieved, and even the dyeing quality will be affected. In particular, the current cellulase polishing treatment is usually carried out before or after dyeing, and the residual alkali components exuded from the fibers d...
