Abstract The crystalline structure of synthetic fiber has been studied by the combined techniques of electron diffraction and dark field electron microscopy. By peeling layers a few tenths of a micron thick from drawn fibers and preparing electron diffraction patterns from them one can resolve structural variations that take place through a fiber. Application of the same sample preparation technique on drawn linear polyethylene fibers combined with dark field electron microscopy can reveal crystalline structures that have an average size and distribution predicted from x‐ray diffraction and lightscattering studies.
