Abstract: A process produces a thermoplastic polyurethane (TPU) fiber with low shrinkage, in particular at a high spinning speed. The resulting fiber can be used for fabric, especially for garments and shoes. The process combines the high-speed spinning process with the heat-setting process. This allows the process to produce a TPU fiber in high productivity, which could greatly decrease the cost. Moreover, the obtained TPU fiber has very low shrinkage of <10%, which makes it well suitable as the main raw material in fabrics.
