Abstract
The opening roller system of fiber separation which is invariably used on all the modern rotor spinners, entails considerable breakage of fibers. Various indirect measures have been proposed over the years for estimating the incidence of such fiber breakage. This paper describes a technique for direct measurement of fiber breakage. It has been shown that the number of fibers that break increases as the opening roller speed is raised. Besides, many fibers undergo multiple breaks at higher speeds. The pattern of fiber breakage is quite similar with opening rollers fitted with pins and saw-tooth wire. A probable mechanism has been preferred when explaining these results on fiber breakage.
