Problems solved by technology

[0004] The patent number is 201510176587.6, and the patent name is a preparation method of viscose fiber containing apocynum extract, which discloses a viscose fiber from apocynum extract, and the fiber prepared is carried out by adding apocynum extract, so The viscose fiber prepared by it has only part of the functionality of apocynum, and lacks the inherent advantages of strength and elongation of cellulose fibers made from natural fibers of apocynum, resulting in the dry and wet elongation at break of the prepared fiber. It is too large, so it is easy to deform during wearing and use, which affects the appearance; at the same time, the antibacterial rate of the apocynum viscose fiber prepared by it is too low for Candida albicans, and it does not have the function of releasing infrared rays

Abstract

The invention provides an animal colloid protein composite apocynum venetum cellulose fiber. The fiber satisfies the indicators of: dry breaking strength of greater than or equal to 3.5cN / dtex, wet breaking strength of greater than or equal to 2.8cN / dtex, an animal colloid protein content of greater than or equal to 3%, dry breaking elongation of 11-13%, and wet breaking elongation of 11-14%. The invention also provides a preparation method of the animal colloid protein composite apocynum venetum cellulose fiber. The method includes preparation of a protein dissolution solution. The preparation steps of the protein dissolution solution include: adding CHAPS, glycerin and thiourea into deionized water and performing stirring dissolving to obtain a CHAPS solution, adding animal colloid protein powder into the CHAPS solution, and conducting stirring, ultrasonic dissolution and heat preservation to obtain the protein dissolution solution. The cellulose fiber prepared by the method provided by the invention has good gloss, protein in the fiber maintains the softness of fiber and better drapability, so that the prepared cellulose fiber has high strength and low elongation, animal colloid protein in the fiber does not run off easily.

Description

technical field [0001] The invention relates to an animal colloid protein cellulose fiber and a preparation method thereof, in particular to an animal colloid protein composite apocynum cellulose fiber and a preparation method thereof. Background technique [0002] Apocynum stem bark is a good fiber raw material and an ideal new natural textile raw material, so it is known as "the king of wild fibers". Clothes made of apocynum fiber by fine processing and weaving have the characteristics of good air permeability, strong hygroscopicity, softness, antibacterial, warm in winter and cool in summer. [0003] Apocynum fiber is thinner than ramie, and its single fiber strength is five or six times stronger than that of cotton. Apocynum fiber can be blended with cotton, wool or silk to be woven into various blended cotton cloths, woolen fabrics, and spun silks. Blended with wool, there are gabardine, serge, veritin, etc.; blended with cotton, there are serge, gabardine, hemp yarn, ...
