Abstract
The present invention relates to a thermoplastic polyurethane fiber and a method for producing the same. A thermoplastic polyurethane material is firstly provided and subjected to a molten extruding process to form a fiber material. Next, an extension process is performed to the fiber material to obtain the thermoplastic polyurethane fiber of the present invention. The thermoplastic polyurethane fiber has a lower thermal shrinking property, thereby meeting requirements of the application.
