Embodiment 1

[0021] Ramie fabric after desizing: 30cm×30cm;

[0022] The formulation of the enzyme treatment liquid is: the enzyme concentration is 1% (to the weight of the fabric), KH 2 PO 4 The concentration is 0.2% (to fabric weight);

[0023] The enzyme treatment process conditions are: pH6, time 60min, temperature 50°C, bath ratio 1:20;

[0024] Results: Compared with the cloth sample treated with enzyme only, the reduction rate was 3 times that of the control, the strength loss was 0.79 times that of the control, the draping stiffness was 1 times that of the control, and the bending stiffness was 0.98 times that of the control.

Embodiment 2

[0026] Ramie fabric after desizing: 30cm×30cm;

[0027] The formulation of the enzyme treatment liquid is: the enzyme concentration is 1% (to the weight of the fabric), KH 2 PO 4 The concentration is 0.5% (to fabric weight);

[0028] The enzyme treatment process conditions are: pH6, time 60min, temperature 50°C, bath ratio 1:20;

[0029] Results: Compared with the cloth sample treated with enzyme only, the reduction rate was 6 times that of the control, the strength loss was 0.74 times that of the control, the draping stiffness was 0.98 times that of the control, and the bending stiffness was 0.98 times that of the control.

Embodiment 3

[0031] Ramie fabric after desizing: 30cm×30cm;

[0032] The formulation of the enzyme treatment liquid is: the enzyme concentration is 1% (to the weight of the fabric), KH 2 PO 4 The concentration is 0.8% (to fabric weight);

[0033] The enzyme treatment process conditions are: pH6, time 60min, temperature 50°C, bath ratio 1:20;

[0034] Results: Compared with the cloth sample treated with enzyme only, the reduction rate was 5 times that of the control, the strength loss was 0.74 times that of the control, the draping stiffness was 0.93 times that of the control, and the bending stiffness was 0.90 times that of the control.

Abstract

The invention discloses a method for increasing cellulose enzyme activity in processing ramie fabrics, which is realized after a series of processes, including ramie fabrics desizing, enzyme treatment, enzyme inactivation, scrubbing and so on. The invention can effectively increase the reduction rate of ramie fabrics, save enzymes and reduce the strength and the stiffness of ramie fabrics, so as to realize the aim of reducing the rigidity of fabrics and increasing the softness of fabrics.

Description

technical field [0001] The invention relates to the technical field of textile engineering, in particular to a method for improving the activity of cellulase in treating ramie fabrics. Background technique [0002] Ramie textiles are breathable, sweat-absorbing, cool and comfortable to wear. They are the preferred textile raw materials for environmental protection and are generally favored by consumers at home and abroad. However, due to the high rigidity, low softness, small elongation at break, poor elasticity, and rough hand feeling of ramie fibers, it will cause itching to the human body when taken, which greatly affects the wearing performance of ramie fabrics, especially in summer. The development of fabrics is more difficult. [0003] Eliminating the itching of linen fabrics has always been an important content in the research of linen textile finishing. When the fibers are rigid, there are many opportunities for the hairs to be straight on the surface, and the cont...
