When you use a hot air stenter, you can further improve the quality of the fabric through soft processing to meet customer requirements. In addition, it is easy to scratch on the guide wheels. In addition, the use of a hot air stenter also helps to keep the fabric surface flat and dimensionally stable, and eliminates wrinkles and creases during dyeing and finishing.

It should be noted that, in order to obtain such an ideal effect, it is necessary to reasonably formulate appropriate setting process conditions during the operation of the hot air stenter. First, the setting temperature is usually determined by referring to the elastic shrinkage and thickness of the fabric. If the temperature is set too high, it will lead to reduced strength, reduced elasticity and the possibility of discoloration of the fabric. Conversely, if the temperature is too low, the fabric will curl, the width will be unstable, and the shrinkage rate will be large.

The speed of the hot air stenter, should be properly controlled. In general, the operating speed mainly depends on the length of the set zone and the set temperature. If it is too fast, it will affect the setting efficiency, and may also cause small wrinkles to be removed during dyeing and finishing. Conversely, if the vehicle speed is slow and the temperature is high, the fabric may turn yellow and the elasticity may decrease.

In addition, another process parameter that needs to be reasonably controlled is the overfeed of the hot air stenter. Generally, after determining the width of the fabric, it is necessary to set an appropriate overfeed amount and tension.

In addition, another process parameter that needs to be reasonably controlled is the overfeed of the hot air stenter. Generally, after determining the width of the fabric, it is necessary to set an appropriate overfeed amount and tension. During the operation of the hot air stenter, 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 amount is large, and the cloth surface is uneven, it is difficult to eliminate the fine wrinkles generated by the fabric during the dyeing process. Conversely, curling occurs during heat setting due to high tension and small overfeed.
