活性染料对杨木单板染色耐光性影响的研究

采用活性染料、酸性染料和直接染料分别对杨木单板进行染色，分析并确定耐光性最佳的染料及此染料染色的最佳工艺参数。结果表明：活性染料染色杨木单板的耐光性最佳；确定出的最佳染色工艺参数为：染料浓度10g/L，染色时间2．5h，染色温度60℃，浴比20：1。这一研究结果为杨木单板仿制珍贵木材提供了理论依据和实际生产工艺参数。

Study on the Influence of Reactive Dyes on Dyeing Lightfastness of Poplar Veneer

In order to analyze and determine the dye with the best lightfastness and the optimum technical parameters of the dye, reactive dyes, acid dyes and direct dyes are used respectively to dye poplar veneer. The results show that the poplar veneer dyed with reactive dyes has the best lightfastness, with the optimmn dyeing process parameters determined as dye concentration 10g/L, dyeing time 2.5h, dyeing temperature 60℃and liquor ratio 20 ： 1. The research results provide a theoretical basis and practical production technological parameters on poplar-based imitated precious wood.
