Abstract

An antiviral composite polyester fiber, characterized in that the polyester fiber comprises the following components and weight ratio: graphene oxide 0.05-0.2%, chitin sulfate 0.5-2.0%, polyester polyurethane polymer 10.0-30.0% , polyester polymer 67.8~89.45%; The polyester fiber includes a core material and a sheath material positioned at the periphery of the core, the aforementioned core material is a polyester polymer, and the aforementioned sheath material is graphene oxide, chitin sulfate Ester, polyester polyurethane polymer composition. The invention also discloses a preparation method of the polyester fiber. The antiviral composite polyester fiber produced by the invention has outstanding antiviral function, long-lasting effect, safety and reliability.

Description

technical field [0001] The invention relates to a polyester fiber, and also relates to a preparation method of the polyester fiber, which belongs to the technical field of chemical fibers. Background technique [0002] In the human living environment, viruses and other microorganisms are ubiquitous, causing great harm to human life and health, especially to infants, the elderly and those with low immune function. [0003] In recent years, outbreaks caused by viruses and the like have occurred frequently. Take influenza as an example, the influenza epidemic is higher than in previous years, and the number of cases and deaths is increasing. Since viruses such as influenza are easy to mutate and bring great difficulties to treatment, prevention is particularly important. In order to prevent, control and treat these infectious diseases, countries around the world have spent a lot of time and energy on research and development of antiviral products. [0004] Antiviral textiles...
