The invention has the beneficial effects that;

1. on one hand, according to the invention, the PVC surface layer and the yarn cushion layer are adhered at a high temperature, and the pattern is printed on the surface of the product through the heat transfer printing process and the cloth pattern high-temperature forming process, so that the produced tablecloth has the dual advantages of the PVC tablecloth and the cloth tablecloth, and has the characteristics of softness, comfort, good wear resistance, water and oil resistance, good flatness, bright and beautiful surface pattern, attractive appearance and the like. In the second aspect, the transfer printing film is transferred to the PVC surface layer and the formed cloth layer and is attached to the yarn cushion layer, and the cloth pattern replaces the existing common polyvinyl chloride mirror surface process, so that the concave-convex layering sense of the cloth pattern is more prominent, and the pattern is exquisite and real. In the third aspect, the production process flow is simple, the requirement on production equipment is not high, the production efficiency is high, the production process is suitable for large-scale mass production, the produced tablecloth has the softness of cloth and the brightness and saturation of PVC printing, which are incomparable with other products, the product performance completely subverts the effect that the prior product can only be used as a household article, and the product produced by the process can be widely used in the field of daily product decoration (such as dining tables, tea tables, television cabinets, curtains and apron materials).
