摘　　要：采用活性染料对预处理后的泡桐单板进行了仿红术染色研究．结果表明；活性染料对泡桐有较好的易染性，泡桐单板经染色后能达到红木商业用材的自然效果；活性染料染色时，由于上染和固色是分开进行的，固色前染料可以充分进行扩散移染，从而有效避免泡桐单板表芯色差现象；通过控制染色温度、时间以及促染剂和固色剂用量，可得到满意的染色效果．试验得出的染色工艺条件为：温度70-80℃，时间3h，促染剂元明粉40g／L，固色剂纯碱20g／L．Reactive dyes were used to dye the veneer of Paulownia Wood for the purpose of imitating padauk. The results show that reactive dyes are better chromophiles for Paulownia wood. In the mean time, as dying and colourfixing are separate, the molecules of dyes can diffuse efficiently before being colourfixed, and difference of colour can be avoided between the surface and inner of the veneer. Satisfying dyeing effects can be obtained by controlling the dyeing temperature and time and by controlling the dosage of the accelerating agent and the colorfixing agent. The better dyeing conditions is 70 - 80℃ of temperature, 3 h of time, Na2SO4 · 10 H2O 40 g/L as accelerating agent and Na2CO320 g/L as colorfixing agent.
