Necessary Conditions For Interlining And Fabric Bonding

1. Bonding machine: Generally, there are two types of bonding machines: roller type and flat type.
2. Bonding conditions: Bonding conditions include bonding temperature, pressing time and pressure. There is a certain connection when the three elements interact within a certain range. When 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 will easily damage the performance and color of the fabric, and it will also easily produce glue penetration. If the pressure is too high, it will easily damage the appearance of the fabric (especially the light and thin fabric).
3. Selection of bonding conditions: before mass production, the bonding conditions must be tested repeatedly to determine the best process conditions
After the interlining is bonded to the fabric. Peel it off and if the hot melt is evenly distributed on the interlining and facing, then the bond is in good condition, otherwise it should be retested. After bonding, the surface of the cloth should be flat, without wrinkles, bubbles, or glue penetration. After bonding, the peel strength, dry cleaning, and water washing performance tests should be carried out, and the test results should meet the production requirements. The bonding effect should meet the style and feature requirements of the clothing.
