Yarn Evenness Tester UI-TX706
Yarn Evenness Tester is used to measure yarn evenness(mass vatiation) by capacitance method. Equipped with an advanced driven system, this evenness tester’s speed ranges from 4m/min to max.800m/min. Besides, this yarn testing machine can also measure yarn diameter, yarn hairiness index and etc. by using different sensors.

2. Yarn Evenness Testing Principle
Unuo Yarn Evenness Tester is suitable to test spun yarn, roving, and sliver. And it can be used to test slub yarn as well. (optional function)
This yarn tester uses the capacitance method for parameter detection. when the tested sample is passing through the machine, its capacitive sensor will auto-transfer the data to the mass of strands. This machine has its own testing software CV-L. The testing data will show as a diagram and can be stored & printed.
For a different types of yarn, different test speeds should be used. We offer test speeds of 4m/min, 8m/min, 25m/min, 50m/min, 100m/min, 200m/min, 400m/min, and 800m/min.
Capacitance testing is an indirect method for yarn evenness. The accuracy of this indirect method can be evaluated by comparing it with yarn evenness measurement direct method–Cutting And Weighing.
