在高温高压下用分散染料对木粉、苄基木粉和乙基木粉进行了染色研究，比较了分散染料对它们的染色性能，并用红外光谱和扫描电镜进行了结构表征。结果表明，染色苄基木粉和乙基木粉的色光与染色涤纶织物的色光接近，比染色杉木粉的色光更鲜艳，且染色苄基木粉的色光比染色乙基木粉的色光更明艳；染料浓度、染色时间和染料分子结构影响染料的上染百分率。扫描电镜分析表明，染料分子充实到改性木材纤维壁的微孔中，并覆盖在苄基木粉和乙基木粉的表面，赋予染色苄基木粉和乙基木粉平滑的表面，有利于光的反射，从而呈现出更明亮的色彩。

The dyeing of fir powder, benzylated and ethylated Chinese fir powder with disperse dyes under high temperature and high pressure was studied.The dyeing performance was compared and their structure of dyed modified fir powders was characterized by infrared spectra ( IR) and scanning electron microscope ( SEM) .The re-sults show that the color shade of dyed modified fir powder was similar to that of dyed polyester fabric, and brighter than dyed unmodified fir powder, especially the benzylated fir powder was the most brilliant.Additionally, the dye concentration, dyeing time and chemical structures of disperse dyes were found to influence the percentage of dye exhaustion.The SEM analysis indicates that dye molecules were adsorbed on the surface of modified fir powder, and anchored into micropores and tiny holes of fiber walls.The resulting smooth surface on modified fir powders is advantageous to reflect sunlight and generate brilliant color shade.
