ABSTRACT

This research was designed to elucidate the effects of ginning and carding rates on the cotton fiber qualities by applying two ginning rates, two lint cleaner systems, and two carding rates. The fiber samples were taken and tested with Mantis® single fiber tensile tester after ginning and carding, and before and after repeated washing/drying the T-shirts produced from the fibers. The breaking strength and the breaking elongation of single fibers were measured and analyzed statistically. Both the breaking strength and the breaking elongation decreased as the processes were compounded, and throughout the repeated washing/drying cycles. Although the magnitudes of decreases in the breaking strengths were small, the breaking elongations were shown to have decreased substantially between carding and washing/drying. After carding, the fibers processed at a higher ginning rate exhibited somewhat greater breaking strengths and breaking elongations.
