If there are several types of Polyester Sd Yarns Manufacturers, such as a two-tube dyeing tank and a four-tube dyeing tank, the difference in the cylinder types may also cause a cylinder difference. Therefore, when the cloth is arranged in the tank, the batch of cloth of the same color should be dyed in the same tank type dyeing tank as much as possible. When the same tank type dyeing tank cannot be discharged, pay attention to the color matching and color matching in the production process. (2) Process consistency.
When a batch of cloth of the same color is dyed in different dyeing tanks at the same time, if the bath ratio, the temperature of the process design, the heating rate, the holding time, the cloth speed, the method and time of dyeing materials are significantly different, It will cause cylinder difference. Therefore, the consistency of the process must be achieved to avoid cylinder differences due to process differences. (3) Differences in the equipment itself. There are some differences in the equipment itself that cannot be avoided, such as design and manufacturing tolerances of some components, differences in sensitivity and accuracy between detection components, etc. Generally speaking,
these differences are not enough to cause differences in dyeing tanks. However, if the manufacturing difference between some key components is too large, it may cause the dyeing tank difference. For example, in the nozzle system, the gap between the air nozzle and the throat pipe is between the tubes of the same tank. The gap will be basically the same, but between different cylinders, this gap may have large differences in the equipment manufacturing process. Because this gap is related to the degree of atomization of the dye solution and the spraying state of the dye solution, it may cause a cylinder difference when it is too large.
Temperature, pressure gauges, pressure sensors, platinum thermistors, level gauges, and various control valves and other components between different manufacturers will objectively have some differences in accuracy and sensitivity, and the differences may be large or even fail. At this time, the difference of the dyeing cylinder is unavoidable, and there is a difference between the cylinder types of different specifications.
