摘要
This study introduces poplar veneer ultrasonic-assisted dyeing. Response-surface methodology was adopted to perform optimum analysis of effects of ultrasonic dyeing on poplar veneer. Results demonstrated that ultrasound increased dye uptake under optimal conditions (210-W ultrasonic power, 57-min assisted dyeing time, and 30-kHz ultrasonic frequency using a dye concentration with mass fraction of 0.52% at 72 degrees C). Under these optimal conditions, dye uptake can reach 42.4%. Compared with nonultrasonic dyeing technologies, ultrasonic dyeing technology for poplar veneer developed in this study increased dye uptake 11.2%.
