1. What Is Heat Transfer Vinyl: Engraving film refers to a heat transfer film that needs to be engraved/cut during the heat transfer process. Under the combined action of heat and pressure, it is separated from the carrier film together with the release layer and is firmly transferred to the surface of the substrate. It is a special functional printing film.  2. Heat Transfer Vinyl Structure: Heat Transfer Vinyl is generally composed of 3 to 5 layers. The three-layer heat transfer film consists of a base layer, a printing layer and an adhesive layer; the four-layer heat transfer film consists of a base layer, a release layer, a printing layer and an adhesive layer; the five-layer heat transfer film consists of a base layer, a release layer, a printing layer and an adhesive layer. It consists of release layer, printing layer, adhesive layer and hot melt adhesive powder layer. 3. Heat Transfer Vinyl Production Process: 1/Substrate Film Preparation There are many kinds of carriers for lettering films. The most widely used one is PET, which has the characteristics of good dimensional stability, uniform tension, good heat resistance and good release properties. Especially in the reproduction of color tone originals, it has obvious advantages. The film specifications such as width, thickness, size and grade are selected according to the manufacturer's requirements. At the same time, check the flatness of the film and whether the tube material has "protruding ribs", "ruffles", etc. that do not meet the quality requirements. 2/Preparation Of Release Agent Release agent is a low-viscosity transparent resin with release, film-forming and adhesive properties. Because the solvent in the release agent evaporates quickly, during the coating process, attention should be paid to controlling the viscosity, that is, controlling The solid content of the release agent is generally controlled at about 23%. If the solid content is less than 19%, the transfer effect of the thermal transfer film after applying the release agent will not be ideal. At the same time, pay attention to the transparency of the release agent, otherwise it will affect the effect of the printing layer. 4. Application Of Heat Transfer Vinyl: It has a wide range of uses and can be applied to various textile fabrics such as clothing, bags, shoes, etc.; for example: sportswear: numbers and trademarks, basketball, football, bicycle clothing, sneakers, swimsuits, and other elastic and blended fabrics etc.; Personalized clothing: personalized T-shirts, advertising shirts, advertising umbrellas, aprons, hats, travel bags from travel agencies, factory and school numbers and logos, etc...
