Embodiment 1

[0011] A one-bath enzyme treatment process for deoxidizing, polishing, and dyeing cotton knitted fabrics, comprising the following steps:

[0012] 1) Add 3 parts by mass of ethyl acetate, 70 parts by mass of deionized water, 85 parts by mass of neutral cellulase, 4 parts by mass of deoxygenase, 35 parts by mass of alkyl polyoxyethylene ether, 15 parts by mass in the reaction kettle Parts by mass of sucrose and 20 parts by mass of sodium chloride were mixed at room temperature and stirred for 55 minutes to obtain an enzyme auxiliary agent for knitted fabrics;

[0013] 2) The gray fabric is pre-treated first, then washed in warm water at 75°C for 25 minutes, then adjusted to neutral pH with nitric acid, then added 2g / L enzyme additive for cotton knitted fabrics, and then dyed after running at 65°C for 25 minutes. Then washed with water, soaped, dehydrated and dried to get the finished product.

Embodiment 2

[0015] A one-bath enzyme treatment process for deoxidizing, polishing, and dyeing cotton knitted fabrics, comprising the following steps:

[0016] 1) Add 2 parts by mass of ethyl acetate, 35 parts by mass of deionized water, 80 parts by mass of neutral cellulase, 2 parts by mass of deoxygenase, 30 parts by mass of alkyl polyoxyethylene ether, 10 parts by mass into the reaction kettle Parts by mass of sucrose and 15 parts by mass of sodium chloride were mixed at room temperature and stirred for 55 minutes to obtain an enzyme auxiliary agent for knitted fabrics;

[0017] 2) The gray cloth is pre-treated first, then washed with warm water at 75°C for 25 minutes, then adjusted to neutral pH with nitric acid, then added 2g / L enzyme additive for cotton knitted fabrics, and then dyed after running at 65°C for 20 minutes. Then washed with water, soaped, dehydrated and dried to get the finished product.

Embodiment 3

[0019] A one-bath enzyme treatment process for deoxidizing, polishing, and dyeing cotton knitted fabrics, comprising the following steps:

[0020] 1) Add 2.3 parts by mass of ethyl acetate, 40 parts by mass of deionized water, 83 parts by mass of neutral cellulase, 2.4 parts by mass of deoxygenase, 33 parts by mass of alkyl polyoxyethylene ether, 14 Parts by mass of sucrose and 18 parts by mass of sodium chloride were mixed at room temperature and stirred for 55 minutes to obtain an enzyme auxiliary agent for knitted fabrics;

[0021] 2) The gray cloth is pre-treated first, then washed in warm water at 75°C for 25 minutes, then adjusted to neutral pH with nitric acid, then added 2g / L enzyme additive for cotton knitted fabrics, and then dyed after running at 65°C for 23 minutes. Then washed with water, soaped, dehydrated and dried to get the finished product.

Abstract

The invention discloses a cotton knitted fabric deoxygenation polishing dyeing-enzyme bath treatment process, which comprises the following steps: 1) sequentially adding 2-3 parts by mass of ethyl acetate, 35-70 parts by mass of deionized water, 80-85 parts by mass of neutral cellulase, 2-4 parts by mass of a deoxidization enzyme, 30-35 parts by mass of alkyl polyoxyethylene ether, 10-15 parts by mass of sucrose and 15-20 parts by mass of sodium chloride into a reaction kettle for mixing at room temperature, stirring for 55 minutes for preparing a knitted fabric-used enzyme additive; 2) pretreating a gray fabric, then washing in 75 DEG C warm water for 25 minutes, then using nitric acid to adjust the pH to neutral, then adding 2g / L of the cotton knitted fabric-used enzyme additive, running at 65 DEG C for 20-25 minutes, dyeing, then washing with water, washing with soap, dehydrating, and drying to obtain a finished product. According to the cotton knitted fabric deoxygenation polishing dyeing-enzyme bath treatment process, before and during a dyeing course with a reactive dye, the enzyme activity remains stable, so that the process steps are shortened, the energy consumption is reduced, and the discharge of sewage is reduced.

Description

technical field [0001] The invention relates to a one-bath enzyme treatment process for deoxidizing, polishing and dyeing cotton knitted fabrics. Background technique [0002] The current one-bath enzyme treatment process for deoxidizing and polishing dyeing of cotton knitted fabrics has unstable enzyme activity before dyeing with reactive dyes and during the dyeing process, which makes the process complex, high energy consumption, and large sewage discharge. Contents of the invention [0003] The object of the present invention is to provide a one-bath enzyme treatment process for cotton knitted fabric deoxygenation, polishing and dyeing, which keeps the enzyme activity stable before dyeing with reactive dyes and during the dyeing process, thereby shortening the process steps, reducing energy consumption, and reducing sewage discharge . [0004] In order to achieve the above object, the technical solution of the present invention is to design a one-bath enzyme treatment ...
