Abstract
To address the urgent need for sustainable development in the textile industry and to provide a high-value-added recycling pathway for waste textiles and polymer scrap, this study focuses on the development of a novel regenerated polyester fiber composite and its potential application in urban public facilities. The composite material is primarily made from regenerated polyester (PET) yarn sourced from post-consumer plastic bottles and waste clothing, produced through specific fiber processing and chemical composite techniques. We conducted systematic durability comparison tests between this new fiber product and traditional materials like pine wood and 6061 aluminum alloy. Experimental results show that the regenerated fiber composite demonstrated excellent abrasion resistance; its wear depth and mass loss were far superior to wood and approached the level of aluminum alloy. After a 1000-hour accelerated aging test simulating long-term environmental impact, the composite’s tensile strength decreased by only 8.2%, showcasing exceptional weather resistance. A service life prediction based on the Arrhenius model indicated that the expected service life of this new fiber product could reach 14.2 years. These findings confirm that the regenerated polyester fiber composite, as a high-performance and long-life engineering material, is not only a significant technological achievement in the field of textile recycling but also offers an innovative solution for the application of organic polymer materials in sustainable urban development.
