This report completes the third phase of a broad study on the relationships of cotton fiber properties to manufacturing performance and quality of manufactured products, and parallels in part the first segment of this study. In this instance, however, the relatively new and more rapidly obtainable fibrograph fiber length measures and Pressley fiber strength values are used in contrast to the less easily obtainable sorter fiber length and Chandler fiber strength measures which were employed in the former study. Fiber fineness, percentage of mature fibers, grade, and staple length are common to both studies.
