Ultra high molecular weight polyethylene film composite fabric and preparation process thereof

Abstract

The invention discloses an ultra high molecular weight polyethylene film composite fabric and a preparation process thereof. The fabric is a composite structural layer and comprises a fabric layer and an ultra high molecular weight polyethylene film layer which is combined on the fabric layer to serve as a composite layer. One surface of the ultra high molecular weight polyethylene film layer and one surface of the fabric layer are molded through heat bonding. The preparation process includes the steps of (1) material preparing, (2) bidirectional tension control over a film, (3) fabric stretching, (4) heat bonding molding, and (5) fabric discharging conducted by feeding the ultra high molecular weight polyethylene microporous film composite fabric onto a fabric roller. The composite fabric prepared through the preparation process of the ultra high molecular weight polyethylene film composite fabric is waterproof, breathable, resistant to high temperature, not prone to deformation and high in composite viscosity. Raw materials contain no fluorine, and environmental friendliness is achieved. The film layer and the fabric layer are molded through heat bonding, so that production cost is reduced, and batch production can be achieved.

Description

technical field [0001] The invention relates to the technical field of composite fabrics, in particular to an ultra-high molecular weight polyethylene film composite fabric and a preparation process thereof. Background technique [0002] Ultra-high molecular weight polyethylene microporous membrane has the advantages of waterproof and breathable, low elongation at break, large work at break, and strong shock absorption ability. At the same time, it has the advantages of anti-ultraviolet radiation, chemical corrosion resistance, and abrasion resistance. With the help of the characteristics of ultra-high molecular weight polyethylene microporous membranes, the combination of ultra-high molecular weight polyethylene microporous membranes and fabrics can be used in clothing, home decoration and other fields. . [0003] As far as the field of outdoor clothing is concerned, people hope that the clothes they wear can be used in both weather and rain. In rainy days, they can not on...

Problems solved by technology

[0004] With the improvement of people's living standards, the requirements for outdoor clothing are getting higher and higher. Currently, the waterproof and moisture-permeable clothing with PTFE microporous membrane as the functional membrane on the market uses a three-layer composite fabric with PTFE as the main raw material. , the cost is high, although it has high water resistance and moisture permeability at the beginning, but because the PTFE membrane is not resistant to washing powder washing, if washing powder is used in washing, the water repellency will be greatly reduced and the service life of the clothing will be affected; and PTFE is not durable Scratch-resistant, PTFE-based composite fabrics need a layer of mesh to protect the PTFE film layer, so PTFE composite fabrics are actually three-layer composite fabrics, resulting in high costs for PTFE composite fabrics
