Relation between the X-Ray Angle of Cottons and Their Fiber Mechanical Properties

Correlations are presented between the spiral angle, as measured by the X-ray angle (40% absorption angle of 002 diffraction are), and the mechanical properties of 16 cot tons. A significant correlation is found for Pressley strength at zero gauge length : however, virtually no correlations exist when cotton strength is measured at 5.0-mm. gauge length. Highly significant correlations are found between the spiral angle and the extensibility properties of cotton fibers, as measured by single fiber elastic modulus and elongation to break.
