Filament yarn testing machine yarn evenness tester is based on the virtual instrument structure. It’s capacitive and photoelectric detection method ,high performance testing instrument for the textile laboratory.It can be used to test evenness of yarns, hairness, roving, slivers which are spun with cotton, wool,flax and short synthetic fiber. It is very helpful for improving and assuring quality of yarns.
The whole machine indicators
