Linen fabric lacks functional properties which can be imparted using CeO nanoparticles; however, the efficiency and durability against the repeated washing is always a big limitation. Wash-durable functionalization thus can be achieved by surface modification using chitosan-based recipes which can also impart additional functional properties to linen. In the present work, the modification of linen fabric was achieved using a chitosan-based recipe followed by in-situ synthesis of CeO nanoparticles on chitosan-treated fabrics. The modified fabric was characterized using FTIR, TGA, SEM and EDX techniques and further evaluated towards functional properties. The modified linen displayed highly effective antibacterial activity against S. aureus and E. coli bacteria. The additional functional properties like wrinkle resistance, UV protection and flame retardancy were also achieved using such dual modification. Most of the functional properties were retained in a satisfactory level after five subsequent washes. The modified linen thus can be claimed as a suitable candidate for functional apparels and technical textiles.
亚麻织物缺乏可以通过 CeO 纳米粒子赋予的功能特性;然而,其在重复洗涤下的效率和耐久性始终是一个巨大的限制。通过使用壳聚糖基配方进行表面改性,可以实现耐洗的功能化,从而为亚麻赋予额外的功能特性。在本工作中,使用壳聚糖基配方对亚麻织物进行改性,然后在壳聚糖处理过的织物上原位合成 CeO 纳米粒子。使用 FTIR、TGA、SEM 和 EDX 技术对改性后的织物进行了表征,并进一步评估了其功能特性。改性后的亚麻织物对金黄色葡萄球菌和大肠杆菌具有高效的抗菌活性。通过这种双重改性,还实现了抗皱、抗紫外线和阻燃等额外的功能特性。经过五次后续洗涤后,大部分功能特性仍保持在令人满意的水平。因此,改性后的亚麻织物可以作为功能性服装和技术纺织品的合适候选材料。
