| 摘 要： | 对毛白杨木材纤维素，半纤维素和木素采用酸性染料桔黄Ⅱ进行加热浸染，观察其染色性能，并采用ＦＴＩＲ分析其染色前后的变化。结果表明：对于酸性染料桔黄Ⅱ，素和半纤维素不能上染，而木质素染色性能良好；ＦＴＩＲ分析表明，三者均未与染料反应生成新的化学官能团，而是木材组分对染料的吸附作用使木材产生颜色。

| Abstract: | The cellulose, hemicellulose and lignin of Chinese white .poplar wood was heated and stained with acidic coloring agent crocus II . The dyeing performances of cellulose, hemicellulose and lignin were observed, and their changes before and after dyeing were also analysed by FTIR method, The results showed that cellulose and hemicellulose can't be stained, while the deying performance of lignin was better. FTIR anatysis showed that no chemical function group generated in the course of reaction between cellulose, hemicellulose, lignin and coloring agent. It is the adsorption action of their constituents to the coloring agent make the wood discolor. |
