A mill study determined the spinning and weaving performance of fiber produced by the Coupled Lint Cleaner. This report discusses the spinning results only. Fiber was processed into carded and combed ring and rotor yarns. When compared to a standard saw gin stand followed by two saw-type lint cleaners, fiber from the Coupled Lint Cleaner produced yarn that was stronger (carded and combed rotor and ring yarn), and had fewer irregularities and imperfections (carded and combed ring yarn).
