Abstract:
     The invention provides a combined technology of cold dissolvant method for hot melt polyester film. First prepare the polyester solution by means of that the quantitative polyester cut sheet mixes with organic dissolvant and are fully dissolved, add relative stabilizator again, then paint the solution high melting point polyester film at normal atmospheric temp., thus form two kinds of melting point polyester combined films after the dissolvants volatilize. The cold combined technology realized the firm combination between two kinds of polyester films and avoided the conventional technological condition that the adhesives need to be smashed with a long-time cooling and to be toasted, so the cost is obviously reduced. The technology is fit for making the hot melt adhesion film of fibrous texture and the heat setting auxiliary material.
