Preparation and characterization of biodegradable polyester fibers enhanced with antibacterial and antiviral organic composites

Abstract

The addition of biodegradable agents and antibacterial and antiviral modifiers in polyester fibers makes the fabric skin-friendly and helps in the effective biodegradation of the fabric, thereby protecting the ecological environment. This study aimed to improve the biodegradability and skin protection effect of polyester fibers by preparing a biodegradable antibacterial and antiviral composite–modified polyester fiber by melting and adding an appropriate amount of anaerobic biodegradable agent and a new antibacterial and antiviral biopolymer material copolymer of 3-hydroxybutyrate and 3-hydroxyvalerate (PHBV). The results showed that the addition of 1% anaerobic biodegradable agent and 1% PHBV antibacterial and antiviral modifier increased the biodegradability of the biodegradable antibacterial and antiviral fiber Fully Drawn Yarn by 50% and its antibacterial and antiviral effect by 10%. The finished fiber fabric had good mechanical properties and antibacterial and antiviral functions. This technique can be widely used in the textile and garment industry to promote green environmental protection and the circular economy of the chemical fiber industry.
