SRRC carding cleaner for cleaning and shortening wool fiber

A carding cleaner, developed at the Southern Regional Research Center for opening and cleaning cotton fiber, was adapted to clean and shorten the length of scoured wool fibers. Investigations were conducted with two types of wire clothing on both cylinders, a fine wire clothing having a high tooth density and a coarse wire clothing having a low tooth density, and two velocity differentials between cylinders. The effects of these conditions on removing trash and shortening the length of the fibers were examined using eight grades of scoured wool. The study showed the cylinders clothed with these wires significantly reduced the length of the wool fibers. It further indicated a low velocity differential between cylinders clothed with coarse wire cleaned the scoured wool as well as the fine wire cylinders and with an improved fiber length distribution.
