Problems solved by technology

[0003] At present, there are few patents on TPU composite cloth. Patent 200910214176 introduces a TPU cloth and its preparation method, which provides a wear-resistant, tortuous and cold-resistant TPU cloth. The TPU layer and the woven fabric layer are bonded by oily glue or water-based glue, which increases the process on the one hand, and increases the cost of glue use on the other hand, and the use of glue reduces the environmental performance of the composite cloth.

Embodiment 1

[0076] Install the black continuous glass fiber 3K twill fabric 2 (Shanghai Zhengxingfa International Trade Co., Ltd., thickness 0.25mm) on the creel 1, lead it out in parallel and evenly, and pass it through the tension roller 3 to ensure smoothness, and then pass through the static elimination device 4 Eliminate the static electricity of the glass fiber, and then the continuous fiber enters the preheating oven 5, where the temperature set in the oven (ie heat paste and temperature) is 200°C.

[0077] At the composite part, the screw extruder 6 extrudes a thermoplastic polyurethane film 8 (thickness 0.05 mm) as the upper surface layer, and the screw extruder 7 extrudes a thermoplastic polyurethane film 9 (thickness 0.05 mm) as the lower surface layer, and The continuous 3K twill cloth used as the middle layer is compounded and bonded under the action of a pair of pressing rollers 10 and 11 (with a distance of 0.35mm). The obtained continuous glass fiber 3K twill cloth and the...

Embodiment 2

[0079] Install the single-sided silver continuous glass fiber 1K twill fabric 2 (Shanghai Zhengxingfa International Trade Co., Ltd., thickness 0.18mm) on the creel 1, draw it out in parallel and evenly, and pass it through the tension roller 3 to ensure smoothness, and then pass it through static electricity. The elimination device 4 eliminates the static electricity of the glass fiber, and then the continuous fiber enters the preheating oven 5, where the temperature (ie heat paste and temperature) set in the oven is 170°C.

Abstract

The invention relates to a piece of thermoplastic polyurethane / fiber composite soft cloth. An intermediate layer is a piece of continuous fiber cloth, an upper surface layer and a lower surface layer are respectively a thermoplastic polyurethane resin layer, and the intermediate layer is connected with the upper surface layer and the lower surface layer through a hot laminating way. The composite soft cloth adopts TPU and fiber fabrics of different types and colors as raw materials, and TPU is bonded with the fabrics in a hot laminating manner, so that the pollution is avoided, the process is simple, the cost is low, the appearance effect is excellent, and the thermoplastic polyurethane / fiber composite soft cloth can be applied to top-grade appearance parts such as cases and vamps.

Description

technical field [0001] The invention belongs to the field of composite material preparation, and relates to a thermoplastic polyurethane / fiber composite soft cloth and a preparation method thereof. Background technique [0002] Thermoplastic polyurethane (TPU) is a relatively special category of elastomers. It is a type of polymer material between rubber and plastic. It has a wide range of hardness, which can vary from Shore 65A-75D, so its performance range is very wide. It has various excellent properties, such as good comprehensive mechanical properties, good hydrolysis resistance, anti-microbial erosion performance, heat resistance, low temperature resistance, chemical corrosion resistance, especially the wear resistance performance, so that it can be used in some apparent outer layers Products have great advantages, shoe materials such as soles and uppers, wire and cable optical cable sheaths, zipper pieces and high-grade plastic straps, watch cases, diving watches, gif...
