Frictional Forces in the Heald Eye

The movement of the yarn against the guide produces some frictional force, which has to be overcome during the movement, leading to an increase in the yarn tension behind the guide. The value of this frictional force depends on a few factors, the effect of which, during the yarn movement as well as at the start of the movement, is discussed here in terms of the experimental findings, for which the heald (heddle) eyes were used as guides. The findings show that the frictional force is a function of yarn speed, yarn tension, contact angle between the yarn and the heald eye, and the diameter of the eye wire.
