Problems solved by technology

Most of the existing antibacterial fabrics are chemically synthesized fabrics, which are not comfortable enough to be used as close-fitting clothing; there are also built-in silver ion antibacterial fabrics, which use spinning-grade antibacterial technology to directly put antibacterial agents into chemical fibers , but silver ions have strong neurotoxicity, which is not conducive to human health; there are also fabrics soaked in traditional Chinese medicine liquid, but this fabric is not washable, and it loses its antibacterial effect after being washed many times; in addition, some fibers It has certain antibacterial properties, but the antibacterial spectrum is small, and it is only inhibitory to a few types of bacteria. There are many types of bacteria in contact with it in life, and it can still infect bacteria

Abstract

The invention discloses antibacterial viscose and a preparation method thereof, belonging to the technical field of textiles. The viscose is prepared by mixing berberine, sodium alginate, chitin and a viscose spinning solution and then spinning the mixture. The prepared antibacterial viscose is prepared by blending the natural extracts including berberine, chitin and sodium alginate, and the spinning solution, is comfort to wear, can effectively prevent plaques and odors on clothes and promote wound healing, is safe and nontoxic, has good hygienic property, is harmless to human bodies after being worn for a long term and is extremely suitable for manufacturing medical nurse uniforms, supplies for rescue, such as bandage gauzes, bedding, such as bed sheets and quilt covers, healthcare baby clothes and underclothes.

Description

technical field [0001] The invention belongs to the technical field of textiles, and more specifically relates to an antibacterial viscose fiber and a preparation method thereof. Background technique [0002] Viscose fiber is a cellulose fiber produced from cotton or other natural fibers. Among the 12 main textile fibers, the moisture content of viscose fiber is most in line with the physiological requirements of human skin, and it has the characteristics of smooth and cool, breathable, antistatic, and brilliant dyeing. As one of the three raw materials for spinning (cotton, polyester, viscose), viscose fiber has the advantages of both cotton and polyester: its moisture absorption, anti-electricity and softness are superior to polyester, and its drapability and dyeability are superior to polyester. Cotton fiber. [0003] Berberine is a common isoquinoline alkaloid with the molecular formula [C20H18NO4]+. It is a long-used traditional Chinese medicine in my country and can ...
