ABSTRACT
The frequency distributions of breaking elongation, breaking strength and toughness of the cotton fibers are positively skewed and also have longer tails than normal distributions. Gamma distribution provides the best fit for the breaking elongation of the three cotton fibers. Weibull distribution provides the best fit for the breaking strength and toughness of cotton I and III, Beta distribution also provides the close fit for the breaking strength and toughness. However, only Gamma distribution fits the breaking strength and toughness of cotton II fibers, whereas neither Weibull nor Beta distribution can fit it.
