Problems solved by technology

[0003] At present, the ecological dyeing of wool fabrics is mainly based on natural plant dyes, extracting natural pigments from plants, and then dyeing wool through traditional dyeing processes, and has achieved certain results, but the fastness of dyed wool fabrics is not very good. Ideal, and the utilization rate of vegetable dyes is not high

Embodiment 1

[0016] The specific steps of the biological dyeing process of laccase to all wool worsted fabrics are as follows:

[0017] 1. Wool fabric pretreatment: put the wool fabric into 90-95℃ hot water and wet it for 10 minutes.

[0018] 2. Configuration of laccase solution: Weigh 50% (omf) laccase and dissolve it in the acetic acid-sodium acetate buffer solution system with pH 4.

[0019] 3. Dyeing process: Put the squeezed wool fabric into a flask containing a laccase solution, and place the flask in a constant temperature oscillating water bath at 50°C for 24 hours.

[0020] 4. Inactivation process: take out the dyed wool fabric and treat it in boiling water for 10 minutes to inactivate the enzyme.

[0021] 5. Washing process: first wash the inactivated wool fabric in hot water at 50-60°C, then wash in cold water, and dry in the air.

[0022] The wool fabric treated with laccase is yellow in color, and its washing and rubbing fastness can reach grade 4-5.

Embodiment 2

[0024] The specific steps of the biological dyeing process of laccase to all wool worsted fabrics are as follows:

[0025] 1. Wool fabric pretreatment: put the wool fabric into 90-95℃ hot water and wet it for 10 minutes.

[0026] 2. Configuration of laccase solution: Weigh 50% (omf) laccase and dissolve it in the acetic acid-sodium acetate buffer solution system with pH 4.

[0027] 3. Dyeing process: put the wool fabric squeezed dry into a flask containing a laccase solution, and place the flask in a constant temperature oscillating water bath at 30°C for 24 hours.

[0028] 4. Inactivation process: take out the dyed wool fabric and treat it in boiling water for 10 minutes to inactivate the enzyme.

[0029] 5. Washing process: first wash the inactivated wool fabric in hot water at 50-60°C, then wash in cold water, and dry in the air.

[0030] The color of the wool fabric treated with laccase is yellowish reddish, and the washing and rubbing fastness can reach 4-5 grades.

Abstract

The invention discloses a process for biologically dyeing wool fabric by virtue of laccase, which belongs to the field of application of bio-enzyme in textile dyeing, and aims at applying the laccase to ecological dyeing of the wool fabric. The wool fabric is colored under the catalytic oxidation action of the laccase on tyrosine components in a wool structure. By virtue of the process, the color of the wool fabric is good in washing resistance, friction resistance and acid resistance. The process is simple, and easy to operate, and is an ecological environment-friendly dyeing method for textile; the consumption of chemicals is reduced.

Description

technical field [0001] The invention relates to a biological dyeing process of wool fabric with laccase, which belongs to the field of textile dyeing. Background technique [0002] With the advancement of science and the improvement of people's living standards, more and more people begin to advocate the pursuit of a healthy, comfortable and high-quality lifestyle. The eco-friendly dyeing process of textiles has also become a research hotspot. As wool is a high-grade textile raw material, the development of ecological wool fabric will increase the added value. [0003] At present, the ecological dyeing of wool fabrics is mainly based on natural plant dyes, extracting natural pigments from plants, and then dyeing wool through traditional dyeing processes, and has achieved certain results, but the fastness of dyed wool fabrics is not very good. Ideal, and the utilization rate of plant dyes is not high. Applying biological enzymes to the dyeing of wool fabrics will be an env...
