The setting time of the stenter is another main process condition for heat setting. After the fabric enters the heating zone, the time required for heat setting can be roughly divided into the following parts.
1. Heating time: The time required to heat the surface of the fabric to the setting temperature after the fabric enters the heating zone
2. Heat penetration time: After the fabric surface reaches the setting temperature, the fibers in the inner and outer parts of the fabric have the same heat penetration time required for the setting temperature.
3. Molecular adjustment time: The time required for the molecules in the fiber to be adjusted according to the setting conditions after the fabric reaches the setting temperature.
4. Cooling time: The time required for the fabric to exit the oven and fix the size of the fabric for cooling.www.haida-textile.com
