A sensing system for measurement of a multilayered blown polymeric film. A feedblock supplies polymeric material streams to an annular blown film die to form a plurality of layers of different polymeric materials. A sensing system is positioned adjacent to a film bubble extruded from the blown film die, wherein the blown film bubble includes annular layers of at least two different polymeric materials. The sensing system emits a signal toward selected circumferential positions around the film bubble and receives a plurality of reflected signals at each circumferential position. Each reflected signal in the plurality of reflected signals is generated at an interface between annular layers that includes a refractive index change detectable by the sensing system. A processor processes the reflected signals from the sensing system, and for each circumferential position determines a layer thickness profile for each polymeric material in the film.

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.
