摘要
探讨了超声波辅助竹片染色在染液质量分数、pH值和染色温度一定的情况下,超声波功率、频率和超声波辅助染色时间等因素对竹片上染率的影响。在单因素实验的基础上,采用响应面法建立了二次回归模型,并对染色工艺进行了优化。研究结果表明:使用超声波辅助竹片染色能够提高上染率,当超声波功率为525 W、频率为30kHz、染色温度为70.0℃、染料质量分数为1.0%、染色时间为52min时,竹片的上染率可达到34.16%,比在相同工艺条件下未使用超声波辅助的提高了8.43%。
Bamboo chips were dyed with ultrasonic assisted process. The effects of ultrasonic power, frequency and ultrasonic assisted dyeing time on the dye uptake were discussed under condition of constant mass fraction of dye solution, pH value, and dying temperature. A quadratic regression model was established with response surface methodology based on single factor experiment, and the process was optimized. The result showed that the dye uptake increases when using ultrasound; the optimized parameters are ultrasonic power 525 W, ultra- sonic frequency 30 kHz, dyeing temperature 70 ℃, dye mass fraction of solution 1.0%, and dyeing time 52 min; the dye uptake reaches to 34.17 %, which increases 8.43 % compared with the process without ultrasonic assistance.
