| 摘 要： | 天然彩色棉是21世纪国际绿色纺织品市场上最具发展潜力的产品之一.现在对天然彩色棉和染色棉没有很好的鉴别方法.利用交叉极化魔角自旋核磁共振(CPMAS-NMR)和傅里叶红外-拉曼(FTIR-Raman)光谱法鉴别天然绿色棉和染色棉;采用棉纤维色素提取液的酸碱可逆色变反应鉴别天然绿色棉、天然棕色棉和染色棉,方法简单快捷有效.

| Abstract: | The natural colored cotton is one of the most development potential products in international textile market in the 21st century. Effective methods to identify natural colored cotton from dyed cotton have not been found. Cross Polarization Magic Angle Spinning Nuclear Magnetic Resonance (CPMAS-NMR) and Fourier Transform Infrared Raman(FTIR-Raman)spectroscopy were used to identify the natural green cotton from the dyed cotton,and the reversible color change of pigment extraction in different pH environment was used to identify both the natural green cotton and the natural brown cotton from dyed cotton. |
