Analysis on Stretching Control of Stenter Stretcher
Sep 17, 2023
Reasonably control the speed of the stenter setting machine equipment. Under normal circumstances, its operating speed mainly depends on the length of the shaping area and the height of the shaping temperature. If the speed of the vehicle is too fast, it will affect the setting effect, and it may also cause fine wrinkles in the dyeing and finishing process. Conversely, if the vehicle speed is slow and the temperature is high, it may cause the fabric to turn yellow and reduce its elasticity.
In addition to the above two conditions, another process parameter that needs to be reasonably controlled is the overfeeding of the stenter setting machine equipment. Generally, after determining the fabric width, it is also necessary to set the appropriate overfeeding amount and tension.
It should be noted that during the operation of the stenter setting machine, the selection of this parameter will affect the weight, elasticity and wrinkles of the fabric surface. For example, if the fabric tension is small, the overfeed is large, and the cloth surface is uneven, it will be difficult to eliminate the fine wrinkles produced during the dyeing process. On the contrary, high tension and small overfeed will cause curling during heat setting.
