Chitosan is a new-age functional biopolymer which can be utilized for functional finishing of cellulose-based textile materials. In the current work, linen fabric was modified using two-stage finishing using chitosan-citric acid and phytic acid-thiourea thus imparting multiple performance characteristics such as wrinkle-free, antibacterial, flame retardant and antioxidant properties. The multifunctional linen fabrics were characterized using FTIR, TGA, SEM and EDX analysis. The fabrics were evaluated for textile properties like tensile strength, bending length, yellowness index, absorbency and functional properties like crease recovery angle, antibacterial activity, UV protection, flame retardancy and antioxidant properties. The durability of functional properties was also evaluated. The finished linen fabric displayed efficient multifunctional properties which were retained to a moderate level till 20 washes.
壳聚糖是一种新型的功能生物聚合物，可用于纤维素基纺织材料的功能整理。在本工作中，采用壳聚糖-柠檬酸和植酸-硫脲两步法对亚麻织物进行整理，赋予其免烫、抗菌、阻燃和抗氧化等多种性能。采用 FTIR、TGA、SEM 和 EDX 分析对多功能亚麻织物进行了表征。对织物的拉伸强度、弯曲长度、黄度指数、吸湿性和功能性能（如折痕回复角、抗菌活性、紫外线防护、阻燃性和抗氧化性）进行了评价。还评估了功能性能的耐久性。整理后的亚麻织物显示出高效的多功能特性，在 20 次洗涤后仍保持在中等水平。
