  1. ELO percent elongation of fibers before breaking, MIC a measurement of fiber fineness or maturity by an airflow instrument that measures the air permeability of a constant mass of cotton fibers compressed to a fixed volume, SFC short fiber content, calculated as the content (%) of fiber shorter than 12.7 mm, STR force required to break a bundle of fibers one tex unit in size, UHM upper half mean fiber length, the average length of the longer one-half of the fibers sampled, UI uniformity index, calculated as the (mean length/UHM) × 100, SE Standard error mean, SD standard deviation
