Abstract

The invention discloses a dyeing and finishing process of all-cotton edible wool knitted fabric. The dyeing and finishing process comprises the following steps that pretreatment is carried out, specifically, a to-be-dyed fabric is put into a water bath, an oil removal agent is added, heating is carried out, caustic soda flakes, sodium carbonate, hydrogen peroxide and a hydrogen peroxide stabilizer are added, gradually heating is carried out, heat preservation is carried out, washing is carried out with water and acid after cooling, and then heating, soaping, cooling and washing with water are carried out; inlet water is heated, deoxygenase is added, and heat preservation is carried out; the pretreated fabric is obtained; dyeing is carried out, specifically, the water bath is heated, a hair eating agent, salt and dye are added, alkali is added after heat preservation, and then heat preservation and heating are carried out; cooling and then washing and pickling are carried out; soaping is carried out after heating, and cooling and draining are carried out after heat preservation; water is fed, an anti-indentation auxiliary agent is added, and then heating, heat preservation, cooling and draining are carried out; wool washing is carried out, specifically, the dyed and wool-eaten fabric is put into a wool washing machine for wool washing, the tension of the wool washing machine is adjusted to be in the most relaxed state, and steam is added to the wool washing machine for heating; and the washed fabric is dried, shaped and subjected to decating. According to the dyeing and finishing process of the all-cotton edible wool knitted fabric, straight streaks of the dyed and finished fabric can be effectively reduced.
