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

Abstract: This invention is directed to a thermoplastic polyurethanes composition comprising polyether-based thermoplastic polyurethane and 1,2-cyclohexane dicarboxylic acid ester and preparation processes thereof. The thermoplastic polyurethane composition has a good mold release behavior in injection molding without undesirably significant shrinkage and surface blooming of final product.
