Problems solved by technology

[0006] However, the hot melt adhesive layer will age with time, and after a long time of use, there will be a problem that the reinforced film will peel off from the fabric, and then lose its advantage of high strength
In addition, the hot-melt adhesive solution contains solvents. Using this method to form reinforced fabrics may cause solvent residues in the reinforced fabrics, which limits the usability of the reinforced fabrics.

Abstract

The invention provides a composite reinforced fabric and a preparation method thereof. The composite reinforced fabric includes high-hardness thermoplastic elastomer yarns and low-hardness thermoplastic elastomer yarns, and the surface of the low-hardness thermoplastic elastomer yarns is slightly fused to adhere to the surface of the high-hardness thermoplastic elastomer yarns. The preparation method of the composite reinforced fabric comprises: weaving high-hardness thermoplastic elastomer yarns and low-hardness thermoplastic elastomer yarns into fabrics, and the melting point of the low-hardness thermoplastic elastomer yarns is 50°C to 150°C; , hot pressing the fabric to obtain a composite reinforced fabric, the hot pressing temperature is greater than or equal to the melting point of the low-hardness thermoplastic elastomer yarn and lower than the melting point of the high-hardness thermoplastic elastomer yarn. Through the above-mentioned technical means, a composite reinforced fabric with strong tensile strength and strong impact resistance can be produced in a relatively simple and environmentally friendly process.

Description

technical field [0001] The invention is applied in the technical field of textiles, in particular to a composite reinforced fabric and a method for preparing the composite reinforced fabric. Background technique [0002] In recent years, due to the advancement of science and technology, people's demand for functional textiles is increasing, and there are different characteristic requirements according to different uses. As far as high-strength textiles are concerned, their strength can generally be increased by adding strengthening agents or processing them with film. [0003] Adding a strengthening treatment agent is currently a widely used method, which is to immerse the fabric in a processing solution containing a strengthening treatment agent, so that a layer of polymer is attached to the surface of the fabric, thereby increasing the strength of the fabric. [0004] However, in order to maintain the feel of the fabric, it is necessary to limit the addition of strengthen...
