Researchers Develop Self-Healing Polyester Fabric for Sustainable Apparel and Industrial Use
Cambridge, UK - March 2025: A team of researchers from the University of Cambridge has developed a self-healing polyester fabric that can repair small tears and scratches automatically, extending the lifespan of textile products and reducing waste. The innovation is based on the integration of dynamic covalent polymers into polyester fibers, enabling reversible bonding under mild conditions.
Traditional synthetic fabrics are prone to damage, leading to premature disposal and contributing to the global textile waste crisis. The self-healing polyester fabric addresses this issue by incorporating a proprietary healing agent into the fiber structure. When the fabric is damaged, the dynamic covalent bonds in the polymer matrix break and re-form upon exposure to slight heat (40-60°C) or pressure, repairing the damage within 10-15 minutes. The healing process can be repeated multiple times without significant loss of fabric performance.
Performance tests show that the self-healing fabric retains 90% of its original tensile strength after three healing cycles. It also maintains excellent dyeability and breathability, making it suitable for apparel applications. In industrial settings, the fabric can be used in protective clothing, conveyor belts, and other applications where durability is critical. The production process is compatible with existing polyester manufacturing lines, allowing for scalable production at a competitive cost.
The research team is currently collaborating with textile manufacturers to pilot the technology in consumer apparel and industrial products. The self-healing polyester fabric is expected to play a significant role in promoting circular economy practices in the textile industry by reducing the need for replacement products and minimizing waste.
