The operation of the Heat Setting Stenter Machine

- Dec 26, 2017-

Heat Setting Stenter Machine is to eliminate the fabric longitudinal stretching in the dyeing process before the dyeing process ,to a large extent, it will meet the size of the design of the customer requirements, this time there will be more pre-fixed fabric Above the throat plate. For example, feed agencies feed 120M every minute.


Of course, we need to pay attention to fixed needle plate will travel 100M per minute, so that 100M position will be directly squeezed into the 120M fabric (positive overfeed +20%), followed by high-temperature stereotypes, after the machine The fabric is also at 100M, eliminating the amount of stretch in the machine direction. At the same time, needle plate distance increases, it will control the fabric width, eliminating the fabric dyeing and dyeing processes before the relevant horizontal shrinkage.


On the other hand, the Heat Setting Stenter Machine is stretched to 100M for finishing (minus 5%) if only 95M of fabric is fed during processing. This is also a way for sellers to make money. It is precisely for this reason that buyers will distribute according to the provisions of vertical and horizontal shrinkage and square meter weight (knitting).


When it comes to spinning and winding in stenters, we have to pay attention to adjusting the overfeed to a large extent. The more common one is that the spinning of the fancy yarns should be overfeed so that One of them takes the lead.


Stereotypes in the operation of roving yarn refers to the negative overfeed (feeding a few hundred meters of cotton wool spinning into millions of meters of yarn); then there will be (precision) winder winding (positive And control the winding height and constant winding density). Furthermore, there are weft weft feeders in the stenter (to control the tension of the yarn, especially the elastic yarn, to ensure non-negative overfeed).
