The role of Hotmelt Adhesive Powder in DTF Printer

DTF hot melt powder plays a key role in the DTF transfer process, mainly including the following aspects:

Adhesion: In the DTF transfer process, the design pattern is first printed on a special transfer film with DTF ink, and then hot melt powder is sprinkled on the printed image. When the film is heated, the hot melt powder melts, forming a bonding layer between the ink and the fabric. Then through the high temperature and high pressure of the hot press, the melted hot melt powder firmly adheres the pattern to the surface of the fabric, achieving the transfer of the pattern from the film to the fabric, ensuring that the transfer image has high definition and good adhesion fastness, and is not easy to fade or flake.

Protection:DTF hot melt powder has the characteristics of temperature resistance, wear resistance, moisture resistance, acid and alkali resistance, corrosion resistance and heat resistance, which can effectively protect the pattern after transfer. It can prevent the pattern from being affected by external environmental factors, such as moisture, chemicals, friction, etc., thereby extending the service life of the product and keeping the pattern bright and complete.

Improve the printing effect: the hot melt powder can fill the tiny gap between the inks after melting, make the surface of the pattern more smooth, improve the color saturation and gloss of the pattern, so that the image after transfer has a better visual effect, the color is more bright and vivid, close to the photo level effect.

Increased flexibility :DTF hot melt powders are usually made of polyester or polyurethane substrates and have some flexibility. After being transferred to the fabric, it can change accordingly with the stretching and deformation of the fabric, and will not cause the pattern to crack or fall off because of the movement of the fabric, so that the clothing or other textiles after the transfer can maintain good wearing comfort and use performance.

The results of the DTF printer process depend on the hot melt powder used, the printing film, the ink, and the drying temperature.Choosing the right materials can help you make high-quality DTF process effects and get more customers' love.
