The recycling and reuse of waste textiles not only help alleviate environmental pollution but also enable resource circulation. Chemical recycling of polyester fibers is one of the effective ways to enhance the value of waste textiles. This paper investigates the optimization of mechanical properties of recycled polyester fibers derived from waste textiles, focusing on analyzing the variation patterns and influencing factors of mechanical properties. By optimizing the process parameters of chemical treatment, the tensile strength, elastic modulus, and other properties of the recycled polyester fibers have been improved, thereby addressing the issues of low fiber strength and unstable performance commonly encountered in traditional textile recycling processes. The research findings provide new theoretical basis and technical support for the recycling and reuse of waste textiles.
