1. Bonding machine: There are generally two types of bonding machines: roller type and flat type.
2. Bonding conditions: bonding conditions include bonding temperature, pressing time and pressure. There are certain connections when the three elements interact within a certain range. As the temperature increases and the pressure increases, the pressing time can be relatively shortened, and vice versa. If the temperature is too high and the pressing time is too long, it is easy to damage the performance and color of the fabric, and it is also easy to produce glue. If the pressure is too high, it is easy to damage the appearance of the fabric (especially light fabric).
3. Selection of bonding conditions: Before mass production, the bonding conditions must be tested repeatedly to determine the best process conditions (when testing samples, the lining supplier should provide bonding conditions for reference).
After the interlining is bonded to the fabric. Peel it off. If the hot melt adhesive is evenly distributed on the interlining and the fabric, the bonding conditions are appropriate, otherwise the test should be repeated. After bonding, the cloth surface should be smooth, without wrinkles, bubbles, and glue. After bonding, the peel strength, dry cleaning, and washing performance tests must be carried out, and the test results must meet the production requirements. The effect of bonding must meet the style and characteristics of clothing.
