Experimental Study on the Effect of Testing Speed on Yarn Unevenness
In this study, the unevenness of compact and combed ring spun cotton yams were examined at four different speeds of 50, 100, 200, and 400 m/min using a capacitance type yarn evenness tester. The CV values of 60s compact package yams increased at first and then decreased with the increase of testing speed. For combed 60s package yam, the CV values decreased at first and then increased gradually at the same time. Hairiness and its deformation were applied to explain the change of unevenness during different testing speed. Frictional rubbing from the tension controller had a significant effect on yam unevenness for Combed 60s package yarns but very slight effect on compact ones. Statistical analysis of the testing data indicated that in some cases the effect of testing speed on yam unevenness was significant and should not be neglected.
