We first time report ultrasonic dyeing of the Nylon 6 nanofibers with two disperse dyes CI Disperse blue 56 and CI Disperse Red 167:1 by utilising ultrasonic energy during dyeing process. The Nylon 6 nanofibers were fabricated via electrospinning and dyed via batchwise method with and without sonication. Results revealed that ultrasonic dyeing produce higher color yield (K/S values) and substantially reduces dyeing time from 60min for conventional dyeing to 30min can be attributed to breakage of dye aggregate, transient cavitation near nanofiber surface and mass transfer within/between nanofibers. Color fastness results exhibited good to very good dye fixation. SEM images exhibit insignificant effect of sonication on morphology of the nanofibers. Our research results demonstrate ultrasonic dyeing as a better dyeing technique for Nylon 6 nanofibers with higher color yield and substantially reduced dyeing time.
我们首次报道了在染色过程中利用超声能量对尼龙6纳米纤维进行两种分散染料（CI分散蓝56和CI分散红167:1）的超声染色。尼龙6纳米纤维通过静电纺丝制备，并采用分批法在有和没有超声处理的情况下进行染色。结果表明，超声染色产生了更高的色深值（K/S值），并将染色时间从传统染色的60分钟大幅缩短至30分钟，这可归因于染料聚集体的破碎、纳米纤维表面附近的瞬态空化以及纳米纤维内部/之间的传质。色牢度结果显示出良好到非常好的染料固着效果。扫描电子显微镜图像显示超声处理对纳米纤维形态的影响不显著。我们的研究结果表明，超声染色是一种更适合尼龙6纳米纤维的染色技术，具有更高的色深值和大幅缩短的染色时间。
