Under normal production conditions, the processing process of the Stenter equipment can be summarized as: rolling car, upper overfeeding, lower overfeeding, main chain, brush, cloth discharge, and cloth drop. The so-called stenter process, in fact, mainly refers to the application of a certain tension to the weft direction of the fabric with the aid of the stenter setting machine.
In this way, after receiving the force, the fabric can effectively remove the defects of uneven cloth edge, weft skew, and uneven width caused by the large warp tension during the pre-processing, dyeing, printing and other processing processes. As for the setting process, it is to properly set the tension of the stenter setting machine equipment, so that the fabric is heated to the required temperature and maintained for a certain period of time under the proper tension condition, so that the fiber molecular chain can be readjusted in a new position.
Then it is cooled down at a certain speed, so as to fix the state of the fabric after heat treatment. In other words, the use of the stenter setting machine can cleverly eliminate the original wrinkles on the fabric and prevent new wrinkles from being generated. In the transmission system, the whole machine mainly consists of 7 synchronous transmission units, 4 circulating fans (8-chamber drying room) and 2 exhaust fans.
About the technical requirements of the stenter setting machine:
First of all, in the actual operation process, in order to ensure a good processing effect, the speed and position of the left and right main chains of the stenter setting machine need to be synchronized to avoid fabric weft skew. Secondly, with 10-segment width control, the amplitude modulation accuracy should be controlled within ±2mm.
In addition, the Flat Screen Printing Machine Factory also needs to strictly control its temperature and tension in accordance with the process requirements during the processing of the stenter setting machine. This is because temperature and tension are two key parameters in the shaping process. Reasonable control of these two parameters will help improve the processing effect of the stenter setting machine.
