| 摘 要： | 用X射线衍射方法研究了天然彩棉、白棉和染色棉的结晶度和取向度,结果表明:天然彩棉的结晶度和取向度明显小于染色棉,但与白棉的差异并不明显,且天然彩棉和白棉的结晶度和取向度因产地不同而有所差异,无规律可寻.在研究取向状态时,发现天然绿色棉呈现两个特征:一是(040)晶面的衍射峰显著低于(200)晶面;二是(002)晶面衍射的强度分布与天然棕色棉、白棉和染色棉明显不同.这两个特征可用于鉴别天然绿色棉的真伪.

| Abstract: | The crystallinity and degree of orientation of naturally colored cottons and white cotton as well as dyed cotton were studied by using X-ray diffraction method. Results showed that the crystallinity and degree of orientation of naturally colored cottons were obviously smaller than that of dyed cotton,but it had a little difference with white cotton. Besides,there were differences between crystallinity and degree of orientation for naturally colored cottons and white cotton owing to the different production ... |
