Abstract

The versatility of nanofibres enables them to be used for various technological applications such as filtration, biomedicine and healthcare, composites, protective and functional textiles. Recently, in addition to the functional properties of electrospun nanofibrous mats, their aesthetic properties have been explored. Herein, attempts have been made to develop digital ink-jet printing of regenerated cellulose nanofibrous mats with reactive inks. First, a cellulose acetate polymer was created to fabricate electrospun cellulose acetate nanofibrous mats, which were then converted into regenerated cellulose nanofibrous mats through deacetylation. Next, the cellulose nanofibrous mats were treated with an alkaline solution then coloured with four (cyan, magenta, yellow and black) commercially available reactive inks by a digital ink-jet printing method using a piezoelectric digital ink-jet printer. Various parameters were investigated, including the optimal concentration of the pretreatment agents, fixation temperature and time, colour yield and the absorbency of the electrospun nanofibrous mats. The digital ink-jet printed cellulose nanofibrous mats exhibited excellent colour yield and colour fastness properties. Morphological analysis through scanning electron microscopy and chemical analysis through Fourier Transform–infrared were also carried out.

用活性油墨数码喷墨打印再生纤维素纳米纤维毡

纳米纤维的多功能性使其能够应用于各种技术领域，如过滤、生物医学和医疗保健、复合材料、防护和功能性纺织品。最近，除了电纺纳米纤维垫的功能特性外，人们还对其美学特性进行了探索。在此，我们尝试用活性油墨对再生纤维素纳米纤维毡进行数字喷墨打印。首先，用醋酸纤维素聚合物制造电纺醋酸纤维素纳米纤维毡，然后通过脱乙酰化将其转化为再生纤维素纳米纤维毡。接着，用碱性溶液处理纳米纤维毡，然后使用压电数字喷墨打印机，通过数字喷墨打印方法，用四种（青色、品红色、黄色和黑色）市售活性墨水着色。研究了各种参数，包括预处理剂的最佳浓度、固着温度和时间、得色率以及电纺纳米纤维毡的吸水性。数字喷墨打印的纤维素纳米纤维毡具有出色的得色率和色牢度特性。此外，还通过扫描电子显微镜进行了形态分析，并通过傅立叶变换红外线进行了化学分析。
