Cotton knitted fabric deoxygenation polishing dyeing-enzyme bath treatment process

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 tr
