An extensive study has been conducted to assess the rotor spinning performance of West Texas cotton which had been cleaned using various combinations of ginning, blowroom and cardroom machinery. It was found that a cleaner material was produced when more cleaning points were used, but cleaning generally caused a reduction in fiber length characteristics, often apparent in slightly reduced yarn strengths.

Gin lint cleaners were more severe in action than mill cleaning equipment. Irrespective of the cleaning route employed, there were no significant differences visible in rotor spinning performance.
