The invention discloses a preparation method of
viscose fiber, and belongs to the technical field of preparation of artificial
fiber. The preparation method comprises the steps of mixing degummed silk cocoons with deionized water, and filtering to acquire a
filter cake; adding
calcium chloride and the like to mix and heating; rotary evaporating to prepare
protein concentrated solution; taking wheat
bran to be mixed with deionized water and boiling; adding mixed
enzyme for enzymolysis, and filtering,
drying, ball milling and screening to acquire separated
fiber particles;
electrospinning the
protein concentrated solution and the separated fiber particles to acquire the
viscose fiber after activating and carbonizing
palm fiber. Therefore, the problems that the traditional
viscose fiber is poor in elasticity and prone to deform when wearing, generates wrinkles and has poor antibacterial endurance are effectively solved. The preparation method provided by the invention is simple in steps, and the acquired
viscose fiber has good elasticity and antibacterial endurance, and no
wrinkle and deformation occurs when wearing.
