Abstract

The invention discloses a preparation method of TPU and PVC blended improved composite fabrics. According to the method, TPU and PVC are blended to fully perform respective characteristics of TPU and PVC, so as to achieve the purpose of complementary advantages; calendaring molding is carried out by a four roll calender method to obtain a TPU and PVC blended film; and on-line lamination is carried out on the TPU and PVC blended film and glued base cloth on a calendar so as to obtain the TPU and PVC blended improved composite fabrics. The composite fabrics have characteristics of excellent mechanical property, wear resistance, environmental protection and the like. The coating of the composite fabrics is uniform and thickness error is less than 0.015mm. The composite fabrics has advantages of firm adhesion, wear resistance and flexing resistance, and can be widely used in application fields of inflatable life jacket, chemical splash suit, water pot, oil tank, sphygmomanometer, medical bed, oxygen bag, inflatable cushion, airbed, inflatable tent, air bag, air cushion ship, waterproof moisture permeable high-grade costuming and the like.

Description

technical field [0001] The invention relates to a method for preparing a fabric, in particular to a method for preparing a composite fabric improved by blending TPU and PVC. Background technique [0002] TPU composite fabric is to use TPU film to compound on various fabrics to form a composite material, and combine the characteristics of the two to obtain a new type of fabric. TPU (Thermoplastic polyurethanes), thermoplastic polyurethane (polyurethane), is a linear block copolymer composed of oligomer polyol soft segment and diisocyanate-chain extender hard segment. TPU can be made into thin films by salivation, film blowing, calendering or coating. It has the superior characteristics of good elasticity, toughness, wear resistance, good cold resistance, environmental protection and non-toxicity. [0003] Polyvinyl chloride (PVC) is one of the most important and widely used artificial polymers, mainly because it has great variability. In the process of manufacturing PVC prod...
