Electrospun nanofibrous mats are popular for their wide technological applications as medical, filtration, sensing and high performance textiles. The potential for coloration of electrospun nanofibrous mats for aesthetic purposes has also been explored recently, and the pigment coloration of cellulose electrospun nanofibrous mats is reported for the first time in this paper. Cellulose acetate electrospun nanofibrous mats were fabricated using electrospinning followed by treatment with sodium hydroxide to synthesise regenerated cellulose electrospun nanofibrous mats. Then the cellulose mats were coloured with commercially available pigments by a pad‐dry‐bake method. Excellent K/S and colour fastness to both washing and light were produced with the application of three commercial pigments. The pH and total dissolved solids content of the coloration wastewater, as well as the mechanical properties of the electrospun nanofibrous mats, were also tested. Attenuated total reflection‐Fourier Transform infrared spectroscopy and scanning electron microscopy analysis were used for characterisation.

纤维素纳米纤维与颜料的着色

电纺纳米纤维垫因其广泛的技术应用而广受欢迎，如医疗，过滤，传感和高性能纺织品。近来还研究了出于美学目的将电纺纳米纤维垫着色的潜力，并且本文首次报道了纤维素电纺纳米纤维垫的颜料着色。使用电纺丝，然后用氢氧化钠处理，以合成再生的纤维素电纺纳米纤维垫，制造醋酸纤维素电纺纳米纤维垫。然后，通过垫干烘烤法将纤维素毡用市售颜料着色。优秀的K / S通过使用三种市售颜料可产生耐洗和耐光色牢度。还测试了着色废水的pH值和总溶解固体含量，以及电纺纳米纤维毡的机械性能。衰减全反射傅里叶变换红外光谱和扫描电子显微镜分析用于表征。
