Problems solved by technology

The main disadvantages of this process are: complex procedures, long equipment assembly line, high energy consumption; long operation time, great damage to fabric fibers; working fluid contains a large amount of caustic soda, bleaching agent, stabilizer, etc., and the discharged wastewater is highly toxic , Environmental pollution is serious and difficult to deal with
Moreover, the operation process is intermittent. In different production stages, the additives are constantly changed according to the needs, and continuous production cannot be realized.

[0032] The fabric used for treatment is woven fabric: 3030 / 10068, T65 / C35 polyester-cotton plain cloth; 16×(150D+40D) / 8365 elastic cloth.

[0033] The processing equipment is a continuous steaming long car process.

[0034] The formula of the treatment liquid is:

[0035] Pretreatment agent composed of biological enzyme and chelating dispersant WS 30g / L

[0036] 100% hydrogen peroxide 14mL / L

[0037] The pretreatment agent contains 60% of biological enzyme and 40% of chelating dispersant WS; wherein the biological enzyme contains 70% of pectinase, 15% of cellulase and 15% of amylase.

[0038] Dissolve the powdery pretreatment agent in warm water at 55°C, stir and homogenize the material, then lower the temperature to 30°C, then add the corresponding amount of hydrogen peroxide, and add water to the required amount to make the treatment liquid; the above fabric padding working liquid Finally, steam at 100°C for 60 minutes; wash with hot water above 95°C for 4 times, then coo...

Embodiment 2

[0041] The treated fabric is woven fabric: 4040 / 13322 poplin; 2016 / 12860, T65 / C35 polyester cotton.

[0042] The processing equipment is a long-car dip-rolling hot-stack process.

[0043] The formula of the treatment liquid is:

[0044] Pretreatment agent composed of biological enzyme and chelating dispersant WS 30g / L

[0045] 100% hydrogen peroxide 12mL / L

[0046] The pretreatment agent contains 55% of biological enzyme and 45% of chelating dispersant WS, wherein the biological enzyme contains 65% of pectinase, 20% of cellulase and 15% of protease.

[0047] Dissolve the powdery pretreatment agent in warm water at 60°C, stir evenly, cool down to 30°C, and then add hydrogen peroxide to prepare a treatment solution; after padding the fabric with the working solution, heat it at 100°C for 60 minutes; wash with hot water above 95°C 3 coats, then lower the temperature to 60°C and wash 1 coat; dry the fabric with a dryer.

Embodiment 3

[0049] Handling fabric is 200g / m 2 Jacquard ribbed cotton knit.

[0050] The processing equipment is an overflow dyeing machine.

Abstract

The present invention relates to a pretreatment one-bath continuous production process before printing and dyeing cotton and blended fabric in dyeing and finishing production of textile industry. Three steps of desizing, refining and bleaching can be combined into one steop to implement, it utilizes biological enzyme and chelate dispersant WS to form the high-effective green pretreatment agent, adds hydroperoxide to prepare treatment liquor. The fabric can be undergone the processes of pad-steaming or pad-thermodepositing treatment on the continuous steaming long carriage, water-washing and drying or undergone the processes of dip dyeing on overflow dyeing machine or dip dyeing machine, water-washing and drying.

Description

technical field [0001] The invention relates to the technical field of dyeing and finishing in the textile industry, in particular to a one-bath continuous production process for the pre-treatment of cotton and its blended fabrics for printing and dyeing. Background technique [0002] In the prior art, the scouring and bleaching process of the pretreatment of textile printing and dyeing includes three processes of desizing, scouring and bleaching, which are respectively completed in three independent processes. The main disadvantages of this process are: complex procedures, long equipment assembly line, high energy consumption; long operation time, great damage to fabric fibers; working fluid contains a large amount of caustic soda, bleaching agent, stabilizer, etc., and the discharged wastewater is highly toxic , The environmental pollution is serious and the treatment is difficult. [0003] In the published Chinese invention patent in the field of textile dyeing and finis...
