Disclosed herein are a real wood film and a method of manufacturing an injection-molded real wood product by using the real wood film. The real wood film includes: a sliced veneer; a non-woven fabric adhered to the bottom surface of the sliced veneer by means of a non-aqueous adhesive, and configured to protect the sliced veneer from moisture; a formation improvement layer adhered to the bottom surface of the non-woven fabric, and configured to prevent the sliced veneer from being wrinkled due to heat applied to the sliced veneer and prevent a crack from occurring; and a thermoplastic adhesive layer adhered to the bottom surface of the formation improvement layer, and configured to enable adhesion to injected resin.

Real wood film and method of manufacturing injection-molded real wood product by using the same

Disclosed therein are adhesive films and a composite of the adhesive film, which can allow an outsole and a midsole to be simultaneously molded in manufacturing footwear. The adhesive film composite is formed of a polyester-type thermoplastic polyurethane (TPU) material, a polyethylene-based coupling agent, montan wax and fatty acid esters with pentaerythritol.

Composite of adhesive films and shoe sole using same

A composite of an adhesive film contains a thermoplastic elastomer selected from rubber-based thermoplastic elastomer or rubber series material, polyethylene-based coupling agent or ethylene vinyl acetate (EVA)-based coupling agent, montan wax, and fatty acid esters with pentaerythritol having five to nine carbons. The adhesive film is typically useful to produce footwear by molding a shoe sole in a mold, and thus, not requiring the conventional labor-consuming and hazardous processes, such as cleaning, primer coating, and bonding processes, to separately produce an outsole, a midsole, and an upper, and then binding together to manufacture a shoe.

Method of manufacturing footwear using adhesive films and composite of adhesive films

Disclosed therein are a method of manufacturing footwear using adhesive films and a composite of the adhesive film, which can allow an outsole and a midsole to be simultaneously molded and formed through the steps of putting the midsole made of EVA foam and the outsole made of rubber into a mold, inserting an adhesive film between the midsole and the outsole, and applying high temperature and high pressure to the midsole and the outsole, thereby not needing to carry out a cleaning process, a primer coating process, and a bonding process when an outsole and a midsole are manufactured, not needing additional facilities for the cleaning and bonding processes, reducing unnecessary manpower, and improving working environments.
