The Crystallite Orientation in Different Varieties of Jute Fibers of Known Strength

Abstract

The orientation of micelles in jute fiber of different varieties, both Tossa and White having different values of intrinsic strength and quality ratio, has been studied. The Hermans' orientation factor, average angle of orientation, and angle at 40% intensity of ten different samples of jute fibers have been determineed from the intensity distribution curves of the equatorial arcs, in the X -ray diffraction photograph. It has been ob served that the orientation factor and angle at 40% intensity have no correlation with the intrinsic strength, but there is a slight correlation if the two varieties of jute White and Tossa are taken separately. For the same value of strength these two varieties have different values of orientation factor. The quality ratio of the yarn has no correla tion with the orientation factor and the angle at 40% intensity. It has been further observed that the average angle of orientation varies from 8° to 9° approximately in the case of jute fibers, and Hermans' orientation factor varies from 0.96 to 0.97, whereas those of ramie are 7°36' and 0.973, respectively.
