Embodiment 1
[0025] (1) Select fresh lotus petiole to remove dirt and impurities on the surface, cut the lotus petiole or lotus root into raw material slag with particle size less than 1cm, extrude and grind the raw material slag to form slurry raw material with particle size less than 1mm, add slurry raw material The Cellusoft L cellulase solution with a concentration of 0.2% was heated and stirred at 25° C. for 30 minutes to obtain lotus fiber pulp with a viscosity of 5000 Pa·s.
[0026] (2) Add sodium hypochlorite solution to the lotus fiber slurry prepared in step (1) with a volume ratio of 100:1, stir evenly, add glacial acetic acid dropwise to neutrality after reacting for 30 minutes, heat and stir, concentrate to form spinning solution, and spin After the silk liquid is vacuum filtered to remove bubbles, at a temperature of 25° C. and a relative humidity of 45%, it is extruded at a rate of 1 ul / min, and wound at a distance of 8 cm to obtain as-spun lotus fiber.

Embodiment 2
[0029] (1) Select fresh lotus root to take out the dirt and impurities on the surface, cut the lotus petiole or lotus root into raw material slag with a particle size of less than 1cm, squeeze and grind the raw material slag to form a slurry raw material with a particle size of less than 1mm, and add the slurry raw material to the concentration 1% Cellusoft Plus cellulase solution, heated and stirred at 35° C. for 90 minutes to obtain lotus fiber pulp with a viscosity of 10,000 Pa·s.
[0030] (2) Add sodium hypochlorite solution to the lotus fiber slurry prepared in step (1) with a volume ratio of 100:5, stir evenly, add glacial acetic acid dropwise to neutrality after reacting for 30 minutes, heat and stir, concentrate to form spinning solution, and spin After the silk liquid is vacuum-filtered to remove bubbles, at a temperature of 25° C. and a relative humidity of 45%, it is extruded at a rate of 2 ul / min and wound at a distance of 12 cm to obtain as-spun lotus fiber.

Embodiment 3
[0033] (1) Select fresh lotus petiole to remove dirt and impurities on the surface, cut the lotus petiole or lotus root into raw material slag with particle size less than 1cm, extrude and grind the raw material slag to form slurry raw material with particle size less than 1mm, add slurry raw material The Cellusoft Plus cellulase solution with a concentration of 0.5% was heated and stirred at 30° C. for 60 minutes to obtain lotus fiber pulp with a viscosity of 8000 Pa·s.
[0034] (2) Add sodium hypochlorite solution to the lotus fiber pulp prepared in step (1) with a volume ratio of 100:2, stir evenly, add glacial acetic acid dropwise to neutrality after reacting for 30 minutes, heat and stir, concentrate to form spinning solution, and spin After the silk liquid is vacuum filtered to remove bubbles, at a temperature of 25°C and a relative humidity of 45%, it is extruded at a rate of 1.5 ul / min, and wound at a distance of 9 cm to obtain as-spun lotus fiber.
