1. setting temperature: the setting temperature may be too low, which may cause the fabric to curl easily after setting. The setting temperature needs to be determined according to the elastic shrinkage and thickness of the fabric. If the temperature is too high, it may lead to the decrease of strength and elasticity, and even make the fabric discolored.
2. Setting speed: The setting speed mainly depends on the length of the setting area and the setting temperature. Too fast may lead to poor setting effect, and fine wrinkles are difficult to solve in the dyeing and finishing process; If the vehicle speed is too slow, especially at high temperature, the fabric will turn yellow and its elasticity will decrease.
3. Overfeeding: After determining the width of the fabric, you need to choose the appropriate overfeeding amount and tension. The choice of overfeed and tension will affect the grammage and elasticity of fabric and the generation of wrinkles in fabric finishing. If the fabric tension is small and the overfeed is large, the fabric surface will be uneven, and the fine wrinkles produced in the dyeing process will be difficult to eliminate; If the tension is large and the overfeed is small, it will lead to curling during heat setting.
For the curling problem, you can also try the following methods:
1. In the pattern design, it can be solved by increasing the size, edging, embedding rib or piping, and embedding adhesive lining on the edge of clothing.
2. After the fabric that is easy to deform is cut, the adhesive lining should be immediately attached to the parts that are easy to stretch and deform, such as the neckline, and then the next step is finalized.
