Notes:
The rectilinear relationship between the integral intensity Bi and fiber density d is used as the basis of a new method for evaluation of the crystallinity index of polyamide fibers (PA-6). To calculate the value of the crystallinity index of the fibers one should have the integral intensity value of the sample and the integral intensities of crystalline and amorphous samples determined under defined instrumental conditions. The method provides a quick and simple means for determining the crystallinity. The method of half-integral intensity may be used only with care when the α-monoclinic polymorphic form dominates in the PA-6 fiber.
