对1.0、1.5、2.0 mm 3种厚度杨木单板进行不同助剂及加量、不同染液及浓度、连续染色次数等染色试验，结果表明：酸性黄和酸性蓝染料对杨木单板染色较为容易，而酸性大红GR染料染色较为困难；固色剂和渗透剂对杨木单板染色效果影响不大，而且加入固色剂导致染色杨木单板可溶性铬含量超标；均染剂NaCl加量1%时杨木单板上染率最高；杨木单板厚度增加，染色时间延长，1.0 mm厚单板染透需5 h，1.5 mm厚单板染透需9 h，2.0 mm厚单板染透需12 h；杨木单板染色时，不同染液要选择相应合适的染液浓度，并且连续染色一定次数后，需及时补充染液，以确保染色效果。

Experiment of dyeing poplar veneer with different thickness was conducted under different treatments, such as different auxiliaries and dosage, different dye and concentration, continuous dyeing times. The results showed that acid red GR was more difficult to dye poplar veneer than acid yellow and acid blue. Fixing agent and penetrant had little effect on dye uptake, and fixing agent could increase content of soluble chromium in dyed poplar veneer. Dye uptake of veneer had the best effect with 1%of NaCl. The dyeing permeability of 1mm poplar veneer needed 5 hours, that of 1.5mm 9 hours and that of 2mm 12 hours. The experiments indicated that different dye solution had different concentration, and needed to be added with different continuous dyeing times.
