摘　　要：为了研究立式减压染色法对青杨生材染色效果的影响,采用活性红X-3B对青杨生材进行减压染色。采用单因素试验法,探讨染色参数对染色材上染面积的影响。结果表明:染色材的上染面积随真空度和染液浓度的增加呈递增趋势;随真空时间的增加呈先增大后减小的趋势;随染色时间的增加呈先迅速增加后逐渐降低并趋于平缓的趋势;在同一染色条件下,同一染色材内,上染面积随染色材高度的增加呈先减小后增大的趋势。In order to investigate the influence of vertical vacuum dyeing method on the green wood of Populus cathayana, reactive red X-3B was adopted to dye the green wood of P. cathayana by the design of single factor experiment in this study. The results showed that the dyeing area increased gradually with the rise of vacuum degree and dye concentration. The dyeing area experienced an increase first and then decreased along with the rise of vacuum time. With the rise of dyeing time, the dyeing area increased quickly, then decreased gradually and reached balance. Under the same dyeing process and same wood, with the rise of wood height, the dyeing area generally decreased first and then increased.
