Embodiment 1
[0021] (1) Adsorption of catechin and oligochitosan on damask fabric: prepare a finishing solution with oligochitosan and catechin with a molecular weight of 2000, and soak the fabric in the above finishing solution; among them, oligochitosan 5 g / L , catechin 2 g / L, pH 5, bath ratio 1:8, dipping treatment temperature 20°C, time 10 min;
[0022] (2) Laccase catalyzed the grafting of catechin and chitosan oligosaccharides on silk fabrics: Add laccase to the treatment system in step (1), in which 0.5 U / mL of laccase, pH 6, liquor ratio 1:8, treated The temperature was 45°C, and the time was 2 h; after the treatment, the damask fabric was fully washed with deionized water at 30°C, and dried at 50°C.
[0023] Sample 1: Damask fabric without any treatment
[0024] Sample 2: no chitosan oligosaccharide was added in the processing of step (1) and the processing of step (2);
[0025] Sample 3: no catechin was added in the treatment of step (1) and step (2);
[0026] Sample 4: proces...
Embodiment 2
[0029] (1) Silk fabrics absorb catechin and oligochitosan: prepare a finishing solution with oligochitosan and catechin with a molecular weight of 3000, and soak the fabric in the above finishing solution; among them, oligochitosan 20 g / L , catechin 10 g / L, pH 6, liquor ratio 1:15, dipping treatment temperature 30°C, time 30 min;
[0030] (2) Laccase-catalyzed grafting of catechin and chitooligosaccharides on silk fabrics: add laccase to the treatment system in step (1), wherein laccase 2 U / mL, pH 5, bath ratio 1: 15, treatment The temperature is 50°C, and the time is 6 h; after the treatment, the fabric is fully washed with deionized water at 30°C, and dried at 50°C.
[0031] Sample 5: silk fabric without any treatment
[0032] Sample 6: no chitosan oligosaccharide was added in the treatment of step (1) and the treatment of step (2);
[0033] Sample 7: no catechin was added in the treatment of step (1) and step (2);
[0034] Sample 8: processed through steps (1) and (2). ...
