TPU composite fabric

Abstract

The invention provides a TPU composite fabric. The TPU composite fabric comprises base cloth and a TPU film adhered to the surface of the base cloth, wherein the base cloth is formed by interweaving warp yarns and weft yarns, the warp density of the warp yarn interwoven fabric is 90-150 pieces per centimeter, the weft density of the weft yarn interwoven fabric is 40-50 pieces per centimeter, the warp yarns are bamboo fiber yarns, and the weft yarns are mulberry silk and polyester drawn textured yarns which are alternately arranged; the TPU film is prepared from the following raw materials: TPUparticles, white carbon black, plant polyphenol, a leveling agent and a stripping aid; the TPU composite fabric is formed by bonding and compounding the TPU film and the base cloth, the base cloth isformed by blending the bamboo fiber yarns, the mulberry silk and the polyester drawn textured yarns, and the TPU composite fabric has good deodorization, air permeability and antibacterial and mildew-proof properties and is matched with the air-permeable and waterproof TPU film attached to the outer side, so that the waterproofness of the composite fabric is enhanced.

Description

technical field [0001] The invention belongs to the technical field of composite fabrics, in particular to a TPU composite fabric. Background technique [0002] As people's requirements for the comfort and waterproofness of fabrics continue to increase, the exploration of developing composite fabrics with waterproof and breathable functions has been going on. In functional composite fabrics, the manufacturing difficulty of composite fabrics with waterproof function is relatively high. [0003] In the prior art, for example, the Chinese invention authorized patent with the application number CN201110080454.0 discloses a waterproof, breathable, luminescent and antibacterial coating cloth, which includes a substrate cloth, and one side of the substrate cloth is sequentially printed with a primer coating Surface rubber coating; the composition and weight ratio of the primer coating are: 76-80% polyurethane, 0.9-2.2% 5-50um artificial zeolite powder, 16-20% DMF solvent; the surf...

Problems solved by technology

During the preparation, the polyether thermoplastic polyurethane film is first prepared by melt blending process, and then the composite fabric is prepared by roller coating process, in which the surface density of the outer layer of polypropylene non-woven fabric is 10-35g / m2, and the inner layer of polypropylene non-woven fabric The surface density of PUR glue is 15-35g / m2, the PUR glue is distributed in dots, and the dosage of PUR glue is 3-5g / m2. Although it has certain antibacterial properties, its air permeability is poor.

[0005] There is also a Chinese invention patent with the application number CN201811426058.7, which discloses a high-strength wear-resistant TPU composite fabric, including a base fabric and a TPU film laminated on the surface of the base fabric; The double rib weave is woven on a double-sided large circular machine to weave into a base fabric; the TPU film is made of the following raw materials in parts by weight: 50-60 parts of modified polyurethane, 6-8 parts of modified attapulgite, N, N-dimethyl 70-80 parts of base formamide, 8-11 parts of filler, 10-14 parts of modified polytetrafluoroethylene; the TPU film is composited on the surface of the base fabric without tension to obtain a high-strength wear-resistant TPU composite fabric, which has air permeability and Bacteriostasis is poor
