High-strength wear-resisting TPU compound fabric and preparation method thereof

Abstract

The invention discloses a high-strength wear-resisting TPU compound fabric which comprises a piece of base cloth and a TPU film coated on the surface of base cloth; bamboo pulp fibers and terylene low-stretch yarns are knitted on a double-side big circular knitting machine in the form of interlock stitch and are weaved into the base cloth; the TPU film is prepared from the following raw materialsin parts by weight: 50-60 parts of modified polyurethane, 6-8 parts of modified attapulgite, 70-80 parts of N,N-dimethyl formamide, 8-11 parts of filler and 10-14 parts of modified polytetrafluoroethylene; the TPU film is compounded on the surface of the base cloth in an unstressing manner, so as to acquire the high-strength wear-resisting TPU compound fabric. According to the invention, bamboo pulp fibers and terylene low-stretch yarns are used for developing the base cloth with an anti-bacterial function, and then a high-strength wear-resisting environment-friendly polyurethane film is compounded, so that the problem of inferior abrasive resistance of fabric is solved; the product is endowed with the advantages of wear resistance, soft luster, moisture absorption, wet permeability, waterproof property, air permeability, antibiosis, deodorization, healthcare, and the like; production cost is greatly lowered.

Description

technical field

[0001] The invention belongs to the technical field of fabric manufacturing, and in particular relates to a high-strength wear-resistant TPU composite fabric and a preparation method thereof. Background technique

[0002] Thermoplastic polyurethane elastomer (TPU) is a kind of heat-plasticized and soluble polyurethane material, which has a unique structure of soft and hard block copolymers. It is widely used because it has both the elasticity of rubber and the processability of plastic It is used in many fields, such as: exterior parts of automobile body, cable sheath, adhesive tape, ski boots, gear, rubber hose, clothing fabric, inflatable products, etc. Usually, different application fields have higher requirements for TPU materials in certain aspects, such as: clothing and shoe materials require TPU fabrics to have better waterproof and moisture permeability, mechanical equipment requires TPU products to have higher mechanical strength, and inflatable prod...
