%X A modified Ruland's method is presented for the calculation of PET fiber crystallinity. By applying the method, we can get rid of the effect of imperfectivity in crystal structure on the value of crystallinity, so that the value can really represent the percent content of crystal part in samples and possesses the correct meaning. The effect of many factors on the diffraction intensity profile is considered, meanwhile a new method for resolution of amorphous halo is given, and a FORTRAN program is also written for the calculation of crystallinity by the use of microcomputer. The results are satisfactory.
