Abstract

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.

Description

technical field [0001] The invention relates to a preparation method of viscose fiber, which belongs to the technical field of man-made fiber preparation. Background technique [0002] Viscose fiber, also known as ice silk and silk cotton, is a major type of man-made fiber. Alkaline cellulose is made from natural cellulose by alkalization, and then reacted with carbon disulfide to form cellulose xanthate, and the viscous solution obtained by dissolving in dilute lye is called viscose. Viscose is wet-spun and a series of After the treatment process, it becomes viscose fiber. Viscose fiber has hygroscopic properties similar to cotton, and its moisture regain meets the physiological requirements of human skin. At the same time, it is smooth, cool, breathable, and antistatic. It has been widely used in clothing, home textiles, and non-woven fabrics. With the continuous development of science and technology, various new functional viscose fibers based on viscose fibers have bee...
