Interpretive Summary: The Coupled Lint Cleaner is an experimental machine that combines the saw ginning and lint cleaning functions into one unit. This configuration has the advantages of (1) requiring less energy to gin and clean the fiber, (2) requiring fewer components of air pollution control equipment, and (3) replacing the traditional feed bar that sets the fiber on the saw cylinder with a mechanism that causes less fiber damage. When compared to a standard high-capacity saw gin stand followed by two saw-type lint cleaners, the Coupled Lint Cleaner produces fiber that is longer, has fewer short fibers, and contains less trash. However, it is unknown how fiber from the Coupled Lint Cleaner performs with respect to spinning and weaving. Preliminary results from a mill study show that when compared to the standard ginning/lint cleaning setup, 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). Weaving results are not yet available. Because the Coupled Lint Cleaner uses less energy and eliminates some auxiliary equipment, there are direct savings in ginning costs.
Technical Abstract: A mill study determined the spinning performance of fiber produced by the Coupled Lint Cleaner. The fiber was processed into carded and combed, ring and rotor yarns. Nominal yarn numbers of Ne16, Ne22, Ne30, and Ne36 were spun from the carded sliver by both ring and rotor methods. Combed stock was spun into nominal yarn numbers Ne22, Ne30, Ne36, and Ne42 by rotor spinning, whereas Ne30, Ne36, Ne42, and Ne50 were produced by ring spinning. When compared to a standard saw gin stand followed by two saw- type lint cleaners, fiber from the Coupled Lint Cleaner produced yarn that had an increase in skein strength, tenacity, yarn elongation, and specific work to break on carded and combed, rotor and ring yarns. The fiber also had a reduction in thin places, thick places, neps, and irregularity of eveness on carded and combed ring yarn. Fiber from the Coupled Lint Cleaner also produced less waste extracted at each major cleaning point prior to sliver preparation, and had reduced combing noils. Weaving results are not yet available.
