Problems solved by technology

[0002] Composite fabric is a new type of material formed by bonding one or more layers of textile materials, non-woven materials and other functional materials with adhesives. EVA hot-melt adhesives are commonly used for adhesives. EVA hot-melt adhesives are a A solvent-free, moisture-free, 100% solid-melt polymer, which is solid at room temperature and melts to a certain extent to become a liquid adhesive that can flow and has a certain viscosity, EVA hot melt adhesive The main component of EVA is ethylene-vinyl acetate copolymer, and it shows good adhesion and adhesiveness, but the EVA of the prior art has the disadvantage of low peel strength, and most of them are low-grade. Therefore, it is urgent to study a peel Hot melt adhesive with high strength to meet market demand

Abstract

The invention relates to a hot-melt adhesive and cloth hot-melt compounding process, which belongs to the technical field of cloth processing. The raw materials of the hot-melt adhesive include ethylene-vinyl acetate copolymer, tert-butyl peroxide-2-ethylhexyl carbonate, L-lysine Amino acid triisocyanate, maleic anhydride, polyester thermoplastic elastomer, polyamide thermoplastic elastomer, polycaprolactone, tackifier, antioxidant, so that the hot melt adhesive has the advantages of high peel strength and convenient processing. At the same time, an upper coating layer is arranged on the upper layer of cloth, glass short fibers are arranged in the upper coating layer, a lower coating layer is arranged on the lower layer of cloth, glass short fibers are arranged in the lower coating layer, and the upper coating layer and the lower coating layer are arranged. A hot-melt adhesive film is arranged between the coating layers, and the finished product is obtained through three times of hot pressing and cooling, which increases the stability and service life of the finished product.
