Circular Melt-Spun Textile Fibers from Polyethylene-like Long-Chain Polyesters.

As textiles contribute considerably to overall anthropogenic pollution and resource consumption, increasing their circularity is essential. We report the melt-spinning of long-chain polyesters, materials recently shown to be fully chemically recyclable under mild conditions, as well as biodegradable. High-quality uniform fibers are enabled by the polymers' favorable combination of thermal stability, crystallization ability, melt strength, and homogeneity.
