Problems solved by technology

Due to the presence of a large amount of alkali in the spinning glue, the wormwood extract in the antibacterial solution will react with the alkali when the spinning glue is blended, and the utilization rate of the active ingredients is low. It is necessary to add a large amount of wormwood extract to ensure the antibacterial effect. The cost is high, while affecting the physical and mechanical properties of the fiber

Abstract

The invention belongs to the field of functional textiles, and particularly relates to a wormwood plant antibacterial and antiviral fiber and a preparation method thereof. The preparation method comprises the steps that (1), a wormwood essential oil inclusion compound is prepared; (2), the prepared wormwood essential oil inclusion compound is added into an acid bath for being uniformly mixed; and(3), a viscose spinning solution is prepared, a cross-linking agent is added into the viscose spinning solution for being uniformly stirred, and a mixture is sprayed into the acid bath for spinning, and the wormwood plant antibacterial and antiviral fiber is obtained. The dry breaking strength of the fiber is 2.5-15.4 cN, the antibacterial level reaches the AAA level, and the antiviral activity value of H1N1 is larger than or equal to 2.0 after the fiber is washed 50 times. The preparation method is simple in process, antibacterial substances of wormwood can be fully utilized, the antibacterial effect of the fiber is lasting, and the wormwood plant antibacterial and antiviral fiber has good laundering durability and can be widely applied to the fields of personal hygiene protection and thelike.

Description

technical field [0001] The invention belongs to the field of functional textiles, and in particular relates to a wormwood plant antibacterial and antiviral fiber and a preparation method thereof. Background technique [0002] In real life, people will inevitably come into contact with various microorganisms such as bacteria and fungi. These microorganisms will grow and multiply rapidly under suitable environmental conditions, and spread diseases through contact, affecting people's physical and mental health. In people's daily life, various textiles are a good living place for these microorganisms and an important source of disease transmission. [0003] With the advancement of science and technology and the improvement of living standards, people have higher and higher requirements for textile and clothing, especially for functional and health-care requirements, such as antistatic, anti-flame retardant, antibacterial, antiviral and so on. Among them, antibacterial fibers a...
