收集国内外不同厂家生产的九种工业用涤纶长丝,用X射线衍射法、透射技术,测定纤维赤道线010、.T10、100三个晶面,子午线105晶面衍射线形。通过分峰处理,计算涤纶纤维内晶粒横截面积、长度和晶粒体积,结果发现国内外纤维的明显差别.初步了解晶粒体积与纤维的热收缩率有关。
X—ray diffraction as well as the transmission technigue have been used to studynine types of poly (ethylene terephthalate) industrial filaments made in various domesticand overseas factories.X—ray diffraction patterns of crystal planes 010,110,100 in equa-tor line and 105 in meridian line ate measured.By means of peak—separating techniquethe average cross-sectional area,the average length and the average volume of the crystalgrains are calculated.The result shows the obvious differences among the various filaments.Primary knowledge,average crystallite size was concerned with shrinkage of fibers.
