Problems solved by technology

This process has been used for decades. The process is lengthy, time-consuming, complicated and strict (pH control is strict), and 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

[0019] In this embodiment, the sample to be treated is pure cotton knitted fabric. Dye the sample to be treated according to the following process: after boiling and rinsing, drain the liquid—wash in hot water (cooling water) for 10 minutes—put in soft water and raise the temperature to 60°C—add HAC (acetic acid) and run for 10 minutes, and adjust the pH value to 6 -7—Add polishing enzyme 988—Run for 15 minutes—Add dye (30 minutes)—Run for 15 minutes—Add Yuanming powder in batches (30 minutes in total)—Run for 30 minutes—Add soda ash in batches (40 minutes in total)—Insulation 60 minutes—after treatment (washing, pickling, soaping, washing, washing)—cloth output—softening agent (special softening machine).

[0020] Among them, polishing enzyme 988 is cellulosic enzyme, the addition amount is 1.5% (mass percentage), and the dyeing bath ratio is 1:10; Yuanming powder is added in 2 times, the first time adding 1 / 3 of the total mass, the second time The addition amount is 2 / 3 of ...

Embodiment 2

[0022] The settings and process flow of this example are the same as those of Example 1, the difference is that the addition of polishing enzyme 988 is 1% (mass percentage), and the dyeing bath ratio is 1:5.

Embodiment 3

[0024] The settings and process flow of this example are the same as those of Example 1, except that the addition of polishing enzyme 988 is 2% (mass percentage), and the dyeing bath ratio is 1:20.

[0025] The technical index characterization of above-mentioned embodiment:

[0026] a. After the technical solution of this embodiment is used, the color fastness index of the fabric is as follows: the soaping grade is 4 grades, the dry rubbing fastness is 4 grades, and the wet rubbing fastness is 3 grades, and the cloth surface is smooth and colorless.

[0027] b. In terms of comprehensive production cost:

[0028] 1. In the technical scheme of this embodiment, only one auxiliary agent of 988 polishing enzyme is added in the process flow. When the dosage is calculated at 1.5%, the auxiliary agent cost: 15KG / ton of cloth×38 yuan / KG = 570 yuan / ton of cloth; In the prior art, after the cloth is boiled, 0.15% TY is used to remove oxygen, and then 0.65% CTA-CL3 and 0.5% HAC are used ...

Abstract

The invention discloses pure cotton knitted fabric deoxidizing polishing one bath process dyeing, and belongs to the technical field of dyeing or printing of textile. The pure cotton knitted fabric deoxidizing polishing one bath process dyeing comprises cooking liquid, draining liquid, hot cleaning and final treatment, and deoxidizing polishing one bath process dyeing is further constituted between the hot cleaning and the final treatment. The deoxidizing polishing one bath process dyeing is that temperature of soft water is raised to 40-60 DEG C a potential of hydrogen (PH) value is adjusted to 5-7, polishing enyme 988 is added to run for 15 minutes, and the dye bath rate is kept as 1:5-1:20. Dye is added (30 minutes) to run for 15 minutes, anhydrous sodium sulphate (30 minutes) is added to run for 30 minutes, and soda ash is added (40 minutes) to keep warm for 60 minutes. The polishing enyme 988 is cellulose biology enzyme, and additive amount is 1-2%. An equivalent effect or a good polishing effect with bath treatment can be obtained, surface of baffeta after treatment is little in lousiness and clear in lines, anti-pilling grades are improved, and at the same time, dye colored light and depth are not affected.

Description

technical field [0001] The invention relates to one-bath dyeing of pure 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 (the pH value is strictly controlled). 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 fibe...
