  1. ELO = percent elongation of fibers before breaking.
  2. MIC = a measure 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.
  3. SFC = short fiber content, calculated as the content (in%) of fiber shorter than 1.27 mm.
  4. STR = force required to break a bundle of fibers one tex unit in size.
  5. UHM = upper half mean fiber length, the average length of the longer one-half of the fibers sampled.
  6. UI = uniformity index, calculated as the (mean length/UHM) x 100.
