Process Parameter of Hot Air Stenter

When you use the Hot Air Stenter, the quality of the fabric can be further improved by soft processing to meet the requirements of the customer. In addition, it is also easy to scratch on the guide wheel. In addition, the use of the Hot Air Stenter setting machine also helps to keep the fabric surface flat and dimensionally stable, and also eliminate wrinkles and creases formed during the dyeing and finishing process.

It should be noted that in order to achieve such an ideal effect, in the process of operating the hot air stenter setting machine, it is necessary to reasonably formulate suitable setting process conditions. First, the setting temperature is generally determined by reference to the elastic shrinkage and thickness of the fabric. If the set temperature is too high, it will lead to a decrease in strength, a decrease in elasticity, and a possibility of discoloration of the fabric. Conversely, if the temperature is too low, the fabric will be curled, the width is unstable, and the shrinkage rate is large.

The speed of the hot air stenter should be controlled properly. Normally, operating speed depends mainly on the length of the setting zone and the setting temperature. If the speed is too fast, it will affect the efficiency of the setting, and it may also cause the fine wrinkles not to be disposed of during the dyeing and finishing process. Conversely, if the vehicle speed is slow and the temperature is high, the fabric may be yellowed and the elasticity may decrease.

Apart from those, another process parameter that needs reasonable control is the overfeed of the hot air stenter. Generally, after determining the width of the fabric, it is also necessary to set an appropriate overfeed amount and tension.

During the operation of the hot air stenter , the choice of this parameter will have an influence on the gram weight, elasticity and fabric surface wrinkles. For example, if the fabric tension is small, the super feed is large, and the cloth surface is not flat, it is difficult to eliminate the fine wrinkles produced by the fabric during the dyeing process. Conversely, since the tension is large and the amount of overfeeding is small, curling will appears during heat setting.

I am not in the field of Industrial work or any sort of organizations yet at the same time, I have some information about it. When I read around then I get a couple of key focuses in regards to mechanical work.
