Analysis of the orientation of supramolecular structures in fibers by the method of X-ray diffractometry

A description is given of a special holder for the x-ray diffractometric analysis of oriented fibers. Use of the holder makes it possible to obtain flat compact specimens and, when slit collimation is used, keeps the conditions for the scattering of radiation by the specimens constant as the fibers rotate about the horizontal axis. The article discusses specific aspects of the equatorial and meridional scattering of x-rays and the orientations of the crystallites for different types of fibers: polycaproamide, aramid, and viscose.
