Embodiment 1

[0031] A kind of cotton woven fabric bleaching and reactive dyeing one-bath process, is characterized in that:

[0032] The technological process is as follows: prepare a dyeing bath (NaOH, sodium silicate, high-efficiency penetrant JFC, scouring and dyeing auxiliaries) at room temperature, put in the cloth sample, heat to 90°C, add hydrogen peroxide, heat up to 100°C, scorch for 60 minutes, and cool down to 35°C, adjust the pH to 7.5, add biological enzymes to eliminate hydrogen peroxide, add dyes and NaCl, dye for 10 minutes, and then add 1 / 3 of the amount of Na 2 CO 3 , dyed for 15min, then raised the temperature to 65°C, and added the remaining 2 / 3 of Na 2 CO 3 Color fixation for 30 minutes, washing, soaping, washing and drying;

[0033] The prescription is: wetting high-efficiency penetrating agent JFC3g / L, sodium silicate 0.5g / L, sodium hydroxide 20g / L, 30% hydrogen peroxide 8g / L, biological enzyme 0.5%owf, NaCl50g / L, NaCl 2 CO 3 15g / L, scouring and dyeing auxiliari...

Embodiment 2

[0036] A kind of cotton woven fabric bleaching and reactive dyeing one-bath process, is characterized in that:

[0037] The process flow is: prepare a dyeing bath (NaOH, sodium silicate, high-efficiency penetrant JFC, scouring and dyeing aids) at room temperature, put in a cloth sample, heat to 85°C, add hydrogen peroxide, heat up to 100°C, scorch for 50 minutes, and cool down to 30°C, adjust the pH to 7, add biological enzymes to eliminate hydrogen peroxide, add dyes and NaCl, dye for 8 minutes, and then add 1 / 3 of the amount of Na 2 CO 3 , dyed for 10-20min, then raised the temperature to 60°C, and added the remaining 2 / 3 of Na 2 CO 3 Color fixation for 25 minutes, washing, soaping, washing and drying;

[0038] The prescription is: wetting high-efficiency penetrant JFC2.5g / L, sodium silicate 0.4-g / L, sodium hydroxide 15g / L, 30% hydrogen peroxide 6g / L, biological enzyme 0.5%owf, NaCl45g / L, NaCl 2 CO 3 12g / L, scouring and dyeing auxiliaries 6g / L, liquor ratio 1:18;

Abstract

The invention relates to a scouring-bleaching and active dye dyeing one-bath process technology for cotton woven fabric. Compared with conditions of conventional dyeing technology, the dye uptake of the disclosed technology is same, and a dyed finished product processed by using the disclosed technology has the fixation rate, the capillary effect, the tearing strength, the dry friction fastness, the dyeing reappearance and the like all according to basic requirements of a conventional dyeing method, and compared with a conventional dyeing technology, the disclosed technology has the advantages of time saving, energy saving, water saving, high production efficiency, light sewage processing burden and the like.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a one-bath process of scouring and bleaching cotton woven fabrics and dyeing with reactive dyes. Background technique [0002] The pretreatment process and dyeing process of traditional cotton woven fabrics are carried out separately, and the two-bath method is used for dyeing. The disadvantage of this process is that it takes a long time, the operation process is relatively complicated, the labor load of the staff is large, the water consumption is large, and the burden of sewage treatment is very serious. With the continuous development of my country's printing and dyeing industry and the recent national government's increasing emphasis on energy issues and environmental protection issues, the simplification of reactive dyeing process has become a very important topic for dyeing and finishing workers. In order to simplify the dyeing process of cotton woven fabrics, people have successi...
