A Nontraditional Method of Cleaning Pima Fiber

M.N. Gillum, C.B. Armijo


An experimental roller gin/lint cleaner was built and tested. The experimental machine combines the ginning and lint cleaning functions into one unit, with lint cleaning being done using a cylinder-type cleaner. Because the roller-ginned lint tufts fall directly onto the cleaning cylinder, a feed works assembly is not needed. The feed works associated with cleaning cylinders is what usually causes fiber damage. The experimental treatment consisted of the roller gin/lint cleaner using a standard spiral-wrapped saw cylinder for lint cleaning, while the control treatment bypassed the cleaning cylinder for lint cleaning and instead used two mill-type/air-jet cleaners. Test results show that lint from the experimental treatment contained more trash than lint cleaned by the mill-type cleaners, but the extra trash was not enough to affect grade. There is more lint loss in the trash of the experimental machine, but turnout remained higher. Also, nep content was lower in the experimental machine. Future tests will include different types of cleaning cylinders. Both the spinning potential and industry acceptance of roller ginned fiber which has been cleaned by nontraditional means is not known at this time.
