Abstract

The invention discloses a dyeing and finishing technique of cellulose fiber textile, which sequentially comprises the following steps of: pretreating, dyeing, water washing, neutralizing, soaping and water washing the fiber textile; and the dyeing technique comprises the steps of: under the conditions of 30 DEG C and bath ratio of 1:7-1:15, adding vinyl sulfone type low-temperature dye with the weigh of 2-10% of the textile, and carrying out heat preservation for 10-15min; then, adding anhydrous sodium sulphate and sodium hydroxide which is 1 / 4-1 / 3 of the total weight, and carrying out heat preservation for 10-15min; adding another sodium hydroxide which is 3 / 4-2 / 3 of the total weight, and carrying out heat preservation for 10-15min; and heating to 40 DEG C at the speed of 1 DEG C / min, carrying out heat preservation for 40-60min, and completing the dyeing technique. The dyeing and finishing technique of the cellulose fiber textile has the characteristics of low using quantity of dye, high soaping fastness, low using quantity of alkali color fixing agent, less pollution discharge and reduced cost.

Description

technical field [0001] The invention relates to a dyeing and finishing process of cellulose fiber textiles. Background technique [0002] At present, in the dyeing and finishing process of cellulose fiber textiles, the following steps are successively included: 1. Pretreatment of fiber textiles, 2. Dyeing, 3. Washing, 4. Neutralization, 5. Soaping, 6. Washing. Among them, in the dyeing step, medium-temperature reactive dyes are used, usually the active groups of vinyl sulfone and monochloro-s-triazine components produced by DyStar or some domestic dye factories, such as 3BS red, 3RS red, B133 Yuanqing and other dyes of this type. The dyeing process is carried out at a temperature of 30°C, and the dye is slowly added in 20 minutes. The addition of the dye is 0.005-10% of the fabric weight, and it is incubated for 15 minutes, and then slowly added in 20 minutes. Sodium sulfate water), the addition amount is 3-100g / L (the amount per liter of water); Slowly add the amount of ...
