The behavior of the 50% x-ray angle, the spiral angle, and the half-intensity angle of crystallite orientation with stress has been investigated. Increase in stress decreases the value of these angles, and the rate of variation does not show a linear relation for the cottons investigated. It is also seen that the 50% x-ray angle may be used for the identification of species of cotton as well as to investigate the strain history of cotton fibers.
