Abstract

The invention belongs to the technical field of cotton fibers, and particularly relates to an antibacterial, antiviral and deodorant cotton fiber and a preparation method and application thereof. Thefiber provided by the invention contains a botanical natural antibacterial agent and a complex, the complex is formed by metal ions contained in an inorganic antibacterial agent and phytic acid, and the cotton fiber has good antibacterial and antiviral properties under the combined action of the botanical antibacterial agent and the complex; meanwhile, beta-cyclodextrin effectively protects the botanical natural antibacterial agent, and the phenomenon that the botanical natural antibacterial agent is damaged or lost in the processing process is avoided; the phytic acid and the metal ions in the inorganic antibacterial agent form complexation, so that the stability of the inorganic antibacterial agent is improved, the antibacterial and antiviral durability of the cotton fiber is further improved, and meanwhile, the introduction of the phytic acid also improves the flame retardance of the cotton fiber; and the beta-cyclodextrin and the cotton fiber are subjected to grafting and crosslinking, so that the bonding performance of the antibacterial agent and the cotton fiber is further improved, and the antibacterial and antiviral durability of the cotton fiber is improved.

Description

technical field [0001] The invention belongs to the technical field of cotton fibers, and in particular relates to an antibacterial, antiviral and deodorizing cotton fiber and its preparation method and application. Background technique [0002] With the development of society and the improvement of people's living standards, more and more pathogenic microorganisms including bacteria and viruses have emerged, which pose a serious threat to human life and health. With the strengthening of people's awareness of health care, higher requirements have been put forward for daily necessities. [0003] Cotton fiber has excellent hygroscopicity and air permeability, is soft and warm, has no side effects when in contact with the skin, and has good hygienic performance. However, cotton fiber is easily polluted by microorganisms and has poor antibacterial and anti-mildew effects, so its application is limited. In order to expand the application field of cotton fiber, there are more and...
