TPU composite fabric

Technical Field

The utility model relates to a compound surface fabric field, specific TPU compound surface fabric that says so.

Background

In order to increase the light-shielding performance of fabrics such as curtain cloth and clothes, opaque films are often used as liners, and fabrics are woven on both sides of the opaque films to form composite fabrics.

Tpu (thermoplastic polyurethanes) materials are a class of polymeric materials between rubbers and plastics, known as thermoplastic polyurethane elastomer rubbers. When the TPU film is used as the lining of the composite fabric, a black opaque material is often coated on one surface of the TPU film or a layer of black film such as a PET film is directly adhered to form a TPU black and white film, wherein one surface of the TPU black and white film is a black surface, the other surface of the TPU black and white film is a white surface, and the white surface is milky white or transparent. The TPU black and white film solves the problem of light tightness of the fabric, and meanwhile, the strength and tear resistance of the fabric are improved by means of the characteristics of the TPU material. However, in a specific research and development test, because the colors of the two sides of the TPU black and white film are different, the colors of the two sides of the fabric are not consistent after the fabric is formed, so that color difference occurs, and the attractiveness of the product is affected. In addition, when the simple three-layer composite fabric produced by the traditional composite process is used in certain severe environments, the strength and tear resistance of the fabric cannot meet the requirements. Based on this, the applicant of the present application develops a TPU composite fabric with higher strength and better use effect through repeated tests.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a TPU composite fabric that intensity is high, excellent in use effect, processing is convenient and the outward appearance is pleasing to the eye.

For solving the technical problem, the utility model discloses a TPU composite fabric's structural feature is including two-layer TPU black white film, and the black face of two-layer TPU black white film sets up relatively and hot pressing laminating as an organic whole or glues as an organic whole, and the white face of two-layer TPU black white film is respectively with weave surface fabric hot pressing laminating as an organic whole or glue as an organic whole, forms TPU composite fabric's multilayer structure.

By adopting the structure, the strength of the lining is increased and the shading performance is ensured by utilizing the mode of involution and bonding of two layers of TPU black and white films; meanwhile, the materials on the two sides of the fabric and the layered structure are symmetrically arranged, so that the overall deformation characteristics of the fabric are kept consistent after the fabric is formed, and the phenomenon that part of the surface of the fabric is wrinkled or the whole fabric is distorted and deformed can be effectively avoided; in addition, the white surfaces of the two black and white films are uniformly outward, so that the color and the chromaticity of the two surfaces of the fabric can be kept consistent, and the attractiveness is improved.

In the multilayer structure of the composite fabric, the layers can be bonded into a whole by adopting a direct hot-pressing forming mode by utilizing the self hot-melting characteristic of the TPU film, and the hot-pressing temperature is generally 80-120 ℃. In order to increase the overall strength of the fabric, the layers are preferably adhered by gluing.

Specifically, the black surfaces of the two TPU black and white films are bonded into a whole through PUR glue, and an inner glue layer is formed between the two TPU black and white films. The white surfaces of the two layers of TPU black and white films are integrally bonded with the woven fabric through PUR glue, and an outer glue layer is formed between the white surfaces and the woven fabric. The thickness of the inner glue layer is larger than that of the outer glue layer.

Wherein, for the thickness of each layer, the thickness of the inner rubber layer is 0.05-0.1mm according to the specification of the fabric; the thickness of the outer glue layer is not more than 0.05 mm. The thickness of the TPU black and white film is 0.1-0.2 mm. The thickness of the woven fabric is 0.1-0.8 mm.

Wherein PUR (polyurethane reactive) is totally called moisture curing reaction type polyurethane hot melt adhesive, and the main component is isocyanate-terminated polyurethane prepolymer. The PUR adhesive is a hot melt adhesive with adjustable adhesiveness and toughness (elasticity), excellent adhesive strength, good high and low temperature resistance, water resistance and wear resistance, and good chemical corrosion resistance and aging resistance. The PUR glue is used for bonding to form a glue layer with a certain thickness, and the elasticity of the PUR glue is adjusted through reasonable proportioning, so that the overall flexibility and tear resistance of the fabric can be enhanced. Because the inner rubber layer is positioned in the center of the layered structure, the overall stability of the fabric can be further ensured by properly increasing the thickness of the inner rubber layer.

To sum up, the utility model discloses have intensity height, excellent in use effect, processing convenience and outward appearance pleasing to the eye.
