Tension Control in the Fabric Dyeing and Finishing Process
The fluctuation of fabric tension in the jigger will determine the amount of dye liquor carried during the jigger dyeing process, resulting in defective products. The roll dyeing and roll-up and stacking of the fabric in the dyeing and finishing process all need to be coordinated with the change of the roll diameter to implement constant linear speed operation. From the perspective of the automatic adjustment principle, no matter how large the speed difference between the two units is, or how large the roll diameter changes, it will cause fluctuations in fabric tension, which are all disturbances to the tension. Therefore, the production process needs to monitor and control the tension variable difference of the fabric on the machine.
