Some recently released cultivars have a fragile seed coat that breaks easily during harvesting and gin processing, and contaminates the lint with fragments of seed coat material. Seed coat fragments cause major problems at the textile mill. Because the cultivars are relatively new, there is no current research on their interactions with harvesting and gin processing. Current research will attempt to remove seed coat fragments, and improve fiber quality attributes such as short fiber content and neps, with newly designed lint cleaner grid bars, a newly designed lint cleaner air-knife grid bar, or newly designed pneumatic fractionator in place of the saw-type lint cleaner. ARS brings to the collaboration scientists and research ginning facilities, while Cotton Incorporated brings scientists and fiber test facilities. Both organizations will gain a better understanding of interactions between seed coat fragments and gin processing. It is hoped that this research will provide domestic and international textile mills with a better quality fiber.
