[0002] TPU film composite textiles are made by compounding TPU film on various fabrics to form a composite material, combining the characteristics of the two to obtain a new type of fabric. TPU, also known as thermoplastic polyurethane rubber or thermoplastic polyurethane elastomer, is a linear block copolymer composed of oligomer polyol soft segments and isocyanate hard segments. TPU film is a dense film made by plasticizing and blowing TPU raw materials. Due to its high tensile strength, elongation, high tear strength, resistance to environmental and chemical corrosion, wide hardness range, and large load-bearing capacity, it is widely used in the textile industry.
