Hot Air Stenter Machine Process Overview and Process Description


Under normal production conditions, the process flow of the Hot Air Stenter machine can be summarized as: rolling, overfeeding, underfeeding, main chain, brush, cloth, and cloth. The so-called tentering process mainly refers to the application of a certain pulling force to the latitude of the fabric by means of a hot air stenter machine.

Thus, after being subjected to the force, the fabric can be effectively removed in the pretreatment, dyeing, printing, etc., due to the large warp tension, the unevenness of the weft, the weft skew, the width, and the like. As for the setting process, the tension of the hot air stenter machine is appropriately set so that the fabric is heated to the desired temperature under appropriate tension conditions for a certain period of time to re-adjust the fiber molecular chain at a new position.

It is then cooled down at a certain speed to fix the state of the fabric after heat treatment. In other words, the use of a hot air stenter machine can subtly eliminate the original wrinkles on the fabric and prevent new wrinkles. In the transmission system, the whole machine mainly consists of 7 synchronous transmission units, 4 circulating fans (8-room drying room) and 2 exhaust fans.

Technical requirements for hot air stenter machine:

First of all, in the actual operation process, in order to ensure a good treatment effect, the left and right main chains of the hot air stenter machine need to be synchronized in speed and position to avoid the weft of the fabric. Secondly, the 10-segment width control should be controlled within ±2mm.

In addition, in the process of processing the hot air stenter machine, it is necessary to strictly control the temperature and tension according to the process requirements. This is because of the two key parameters of the temperature and tension in the shaping process. Reasonable control of these two parameters helps to improve the processing effect of the hot air stenter machine.
