Nanometer modified plant fiber spun filament

[0046] Embodiment 1: Preparation of nano-modified plant cellulose

[0047] (1) Enzymolysis: Cut natural plant fiber materials (jute, loofah or other natural fiber materials) into fibers with a length of 0.5~3cm, cook them in an electric heating constant temperature water bath, and stir them magnetically for 30 minutes. After the stirring is completed, filter them with suction , and dried in an oven at 105±3°C to obtain dried natural plant fibers. Enzymolyze with a compound enzyme composed of pectinase: laccase: hemicellulase, and enzymolyze at a temperature of 55±3°C for 12 hours to obtain enzymatically hydrolyzed plant fibers. The ratio of pectinase: laccase: hemicellulase in the compound enzyme is 1:2:2, and the amount of compound enzyme added is 5% of the mass of natural plant fiber material.

[0048] (2) Dissolution: Inactivate the natural plant fiber after enzymolysis at 95°C for 10 minutes, then filter the plate and frame, wash the filter residue and dry it at 50±3°C fo...

[0055] (1) Enzymolysis: Cut natural plant fiber materials (jute, loofah or other natural fiber materials) into fibers with a length of 0.5~3cm, cook them in an electric heating constant temperature water bath, and stir them magnetically for 30 minutes. After the stirring is completed, filter them with suction , and dried in an oven at 110±3°C to obtain dried natural plant fibers. Use pectinase: laccase: hemicellulase compound enzyme to enzymolyze, and enzymolyze for 10 h at a temperature of 45±3°C to obtain enzymatically hydrolyzed plant fibers; in the compound enzyme, pectinase: laccase : The ratio of hemicellulase is 1:0.5:0.5, and the amount of compound enzyme added is 8% of the mass of natural plant fiber material.

[0056] (2) Dissolution: Inactivate the natural plant fiber after enzymolysis at 95°C for 10 minutes, then filter the plate and frame, wash the filter residue and dry it at 50°C~60°C for 5 hou...

[0061] Embodiment 3: the preparation of nano-modified plant cellulose

[0062] (1) Enzymolysis: Cut natural plant fiber materials (jute, loofah or other natural fiber materials) into fibers with a length of 0.5~3cm, cook them in an electric heating constant temperature water bath, and stir them magnetically for 30 minutes. After the stirring is completed, filter them with suction , and dried in an oven at 110±3°C to obtain dried natural plant fibers. Use pectinase: laccase: hemicellulase to enzymolyze the compound enzyme, and enzymolyze it for 24 hours at a temperature of 50±3°C to obtain the enzymatically hydrolyzed plant fiber; in the compound enzyme, pectinase: laccase : The ratio of hemicellulase is 1:0.5:0.5, and the amount of compound enzyme added is 1% of the mass of natural plant fiber material.
