Excerpt from Evaluation of the Fibrosampler and the Digital Fibrograph for Sampling Cotton Fibers and Measuring Length Characteristics

None Of the experimental measurements Of length and length distribution proved to be more valuable in explaining variation in spinning test results than the percent and 50 percent span lengths. The 50 percent span length seemed to be more highly related to spinning performance than the uniformity ratio. For combed yarn, the Digital percent span length for ginned lint, card sliver, and comber sliver explained as much Of the variation in break factor as the array upper quartile length. Array percentage Of fibers shorter than one half inch, array coefficient Of length variability, and Digital 50 percent span length explained as much Of the variation in break factor as the percent span length or array upper quartile length. Digital and array measurements of length distribution for the ginned lint seemed to be Of equal significance in explaining end breakage, but array percentage Of fibers shorter than one-half inch for card and comber sliver was significantly better than the uni formity ratio.
