Abstract

A thermoplastic complex yarn with thermoforming function and thermoplastic fabric therewith are provided. The thermoplastic complex yarn is formed according to a low temperature hot melt fiber wound around the peripheral of a high strength fiber. The thermoplastic complex yarn can be further alternant-plaited with a general yarn to form as a thermoplastic fabric. And, when the thermoplastic complex yarn or the thermoplastic fabric is under hot pressing by a hot-pressing die, the low temperature hot melt fiber can be thermoformed, and further collocated with the high strength fiber for supporting, thus, the thermoplastic complex yarn or the thermoplastic fabric can be formed into various shapes by various hot-pressing dies for increasing the application field thereof, and which can be as the major material of the external package box, such that achieves the purpose of ecology environment protection.
