DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention relates to a thermoplastic polyurethane film (TPU Sheet), and more particularly to a heat having fabric dye transfer resistance (migrati ο η) barrier property A composition and a method for producing a plastic polyurethane film. [Prior Art] According to the thermoplastic polyurethane (ΤΡϋ), it is a kind of synthetic rubber (Synthetic Rubbers), which has the advantages of being durable and extremely tough, not easily scratched, not easy to be shaped after molding, high in insulation, and high in heat resistance. And because T P U has excellent physical and chemical properties, it can be widely used in different fields. Generally, the three processing methods of thermoplastic polyurethane film are mostly processed by high-frequency high-temperature hot cutting method, and the processing temperature can be up to 30 〇C or more; however, the fabric with poor dyeing fastness, such as polyester fiber (Polyester) And nylon fiber (Nylon), which is at a high temperature above 30 °C, easily causes the dye on the fabric to migrate to the thermoplastic polyurethane film. In addition, thermoplastic polyurethane membranes are currently used in a large number of garment and bag labels. If the fabric dye is transferred to the surface of the thermoplastic polyurethane film after high-temperature hot-cutting, it will contaminate the whole garment or bag. Seriously affecting the appearance, and even leading to clothing and bag sales operators will be subject to huge customer complaints. In view of the above, in order to completely solve the above-mentioned apparent migration phenomenon, the present invention proposes a method for manufacturing a thermoplastic polyurethane film sheet and a thermoplastic polyurethane film which can avoid the migration of a fabric dye, thereby improving the conventional defects.
