Operating Procedures of Concave and Convex Embossing Machines for Fabrics

Operating a concave and convex embossing machine for fabrics requires careful attention to detail to achieve the desired results.

The first step is to adjust the temperature of the embossing machine. Generally, the upper die temperature is set between 150 - 180 °C, while the lower die is set at 120 °C. However, these temperatures may need to be adjusted according to the size of the die and the temperature resistance of different fabrics. For thicker or more heat - resistant fabrics, a slightly higher temperature may be required. Use the machine's temperature control panel to set the appropriate values and allow the machine to reach the set temperatures before proceeding.

Next, it's time to prepare the embossing silicone. Mix 100 g of embossing silicone ink base (such as XG - 360 KY - 55 or XG - 360 KY - 60) with 10 g of catalyst. It's important to ensure thorough mixing for consistent results. When applying the embossing silicone, print two squeegees at a time using a 120 - mesh stencil. Select the appropriate plate according to the fabric type. For example, a coarser - textured fabric may require a different plate design compared to a smooth - textured one.

Once the silicone is prepared and the machine is heated, it's time to emboss the pattern. Place the fabric on the machine and ensure it is properly aligned. The pressed cloth piece is then held on the embossing machine for 8 - 15 seconds to set the shape. The exact time may vary depending on the fabric and the complexity of the pattern. Some fabrics with rough materials may need an additional step. A layer of cloth can be placed on the printed silicone ink surface before embossing. Make sure to do this when the silicone ink is still wet to ensure proper adhesion.

After embossing, it's important to check for any issues. If the silicone ink is not cured or sticks to the mold, it could be due to incorrect mold temperature or fabric - related issues such as poisoning (if the fabric contains certain chemicals that react with the silicone). Allow the embossed fabric to sit for 24 hours before conducting a wash test to ensure the durability of the embossed pattern. It's also crucial to note that the above operating procedures are based on general guidelines. Since the materials used by each customer and the production environment may vary, it's advisable to conduct small - scale tests first and adjust the process as needed before starting mass production. This will help to ensure that the final embossed fabric meets the desired quality standards.
