PE and EVA composite fabric and production process

Abstract

The PE and EVA composite fabric comprises a corduroy fabric layer; the top surface of the corduroy fabric layer is covered with a water absorption cotton layer; first air holes distributed in an arraymode are formed in the water absorption cotton layer; an anti-tearing protection layer is arranged on the top surface of the water absorption cotton layer; during use, when the fabric is pulled by anexternal force, the tensile force can be effectively dispersed to all directions by using a hexagonal honeycomb structure, so that the acting force of the tensile force on a single group of fiber wires is reduced, and the single group of the fiber wires is prevented from being broken; when one fiber wire is used, the other fiber wires can be dispersed through a honeycomb, so that the further expansion of a torn opening is effectively avoided; when gas in the fabric is about to permeate out, the gas flows out through the first air holes and the second air holes, so that the air permeability ofthe fabric is improved, and the fabric is more comfortable to wear. And the wearing comfort of the fabric is further improved.

Description

technical field [0001] The invention relates to the technical field of PE and EVA composite fabric production, in particular to a PE and EVA composite fabric and a production process. Background technique [0002] Polyethylene (referred to as PE) is a thermoplastic resin obtained by polymerization of ethylene. In industry, it also includes copolymers of ethylene and a small amount of α-olefin. Polyethylene is odorless, non-toxic, feels like wax, and has excellent durability. Low temperature performance (the lowest operating temperature can reach -100~-70°C), good chemical stability, can withstand the erosion of most acids and alkalis (not resistant to acids with oxidizing properties), insoluble in general solvents at room temperature, low water absorption, and electric Excellent insulation; ethylene-vinyl acetate copolymer is a general-purpose polymer, the English abbreviation is EVA, with water resistance, corrosion resistance, heat preservation, etc. [0003] The tear-res...

Problems solved by technology

[0003] The tear-resistant protective layer in the existing PE and EVA composite fabrics is mostly made of traditional cross weaving technology. When the fabric is pulled by external force, since the pulling force only acts on a single group of fibers, it is easy to cause the fibers to break. And when one of the fiber filaments is broken by force, the remaining fiber filaments will continue to be subjected to tension, which will continue to expand the tear opening. In addition, the existing PE and EVA composite fabrics have poor air permeability and no shock-absorbing effect, so The wearing comfort of the fabric is reduced, so we propose a PE and EVA composite fabric and production process to solve the above problems
