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.
