在竹篾的染色过程中，研究了添加双季铵盐表面活性剂来改善染色效果。探讨了表面活性剂的用量、染色时间、温度等因素对竹篾色差值的影响，采用响应面法对染色工艺进行了优化，研究结果表明，表面活性剂能够有效地提高色差值。当表面活性剂的用量为0.9%、染色温度93.0 ℃、染料质量分数为0.7%、染色时间为60 min时，竹篾的色差值可达到70.13 NBS，比在相同工艺条件下未加入表面活性剂时，提高了15.76 NBS。

The technology of adding bis-quaternary ammonium salt surfactant to improve the dyeing effects of bamboo split was studied. The influences of surfactant dosage, dyeing time, and dyeing temperature on the color difference of bamboo split were discussed. The dyeing process was optimized and analyzed by response surface methodology. The result showed that the surfactant can increase the color difference value. It can reach 70.13 NBS when surfactant dosage is 0.9%, the dyeing temperature is 93 ℃ and the dyeing time is 60 min; the color difference value is 15.76 NBS higher comparing with the method without surfactant.
