[0004] CN105421088A discloses a silver fiber waterproof and moisture-permeable fabric. The silver fiber waterproof and moisture-permeable fabric includes a TPU waterproof and breathable membrane and a fabric body. The fabric body is woven from warp yarns and weft yarns. The warp yarns are silver fibers. The weft yarn is blended with nylon and polyester. Although the present invention can be waterproof and moisture-permeable to a certain extent, the TPU waterproof and breathable membrane has low mechanical strengths such as hardness, tensile strength, and tear strength, and is resistant to high water pressure. Environmental waterproof and moisture permeability is weak

Abstract

The invention provides a waterproof TPU composite material, which is characterized in that the waterproof TPU composite material comprises a two-layer structure, the outer layer is a waterproof TPU polymer layer, and the inner layer is a TPU film layer. The waterproof TPU polymer layer adopted by the invention not only has relatively strong waterproof performance and barrier performance, but alsohas high hardness, high tensile strength and high tear strength, and is green and environment-friendly, good in air and moisture permeability and comfortable in hand feeling.

Description

technical field [0001] The invention belongs to the technical field of composite fabrics, and in particular relates to a waterproof TPU composite material and a preparation method thereof. Background technique [0002] In the textile industry, we generally require films that can prevent the passage of liquids and allow water vapor to escape. In order to achieve the perfect combination of these two functions, it is necessary to make the coating or film both permeable to water vapor and barrier to liquid. Dense films and microporous films can be used. Currently, one of the most popular waterproof and moisture-permeable films is TPU film. [0003] 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. Macromolecular diols and isocyanates are connected to form a long chain structure. Because the molecular chain is long, it shows flexibility...
