Problems solved by technology

[0002] At present, the existing waterproof fabrics mainly include radiation-proof, radiation-proof and flame-retardant, waterproof, breathable and moisture-permeable waterproof fabrics. Although these waterproof fabrics have corresponding functions and uses, according to the current usage, these existing Waterproof fabrics also have the following deficiencies: on the one hand, waterproof fabrics are used to make raincoats, ponchos, tents, and most of the composite and coating materials are PVC (polyvinyl chloride) or polyurethane. This material does not meet environmental protection requirements. It contains Toxic substances, such as plasticizers, industrial talcum powder, industrial calcium carbonate powder, plastic stabilizers, old plastic recycling, aluminum oxide, zinc borate, paraffin oxide, acrylic acid, etc., are obviously harmful to the human body after being made into raincoats, ponchos, and tents. Harmful to health; on the other hand, after the waterproof fabric is used, it cannot be separated naturally even in the soil for fifty years, which has a great impact on the environment; in addition, raincoats and ponchos made of this waterproof fabric are not only Heavy, uncomfortable to wear, and easy to harden and shatter when exposed to cold, easy to delaminate and degumming after hand washing or machine washing

Abstract

The invention relates to the technical field of textile fabrics and particularly relates to an environment-friendly high-cold-resistance combined type waterproof fabric and a production method thereof. The waterproof fabric comprises a textile fabric layer and an EVA (ethylene-vinyl acetate copolymer) film layer, wherein the outer surface of the textile fabric layer is coated by the EVA film layer, and the EVA film layer is mainly formed by combining EVA particles, an enzyme-prevention agent, a stabilizer and a hot melt adhesive agent. The waterproof fabric is prepared by the following steps of: firstly, carrying out pulp preparation and dyeing on a textile fabric; carrying out three-prevention processing on the front surface of the dyed textile fabric, and coating a hot melt adhesive coating on the back surface of the dyed textile fabric; blending and stirring the EVA particles, the enzyme-prevention agent, the stabilizer and the hot melt adhesive agent to be in a paste state, and calendering the paste into an EVA film by utilizing a calender; heating the hot melt adhesive coating and the EVA film by utilizing a laminator, and carrying out laminating and compositing; and cooling so as to obtain a finished product, and carrying out reeling and packaging. Compared with the prior art, the waterproof fabric has the advantages of being light in weight, comfort to wear, high in cold resistance, free from toxin and metal, health and harmlessness to human bodies and high in environmental friendliness, can be naturally separated in soil after being wasted, can not influence the environment and avoids the damage of the conventional PVC (polyvinyl chloride) to the soil environment.
