Functionally modified fabrics produced using sustainable techniques are in huge demand in today's world. In the present work, cotton fabric was modified using layer-by-layer two-stage finishing method using a solution of chitosan in citric acid (CS) and sodium lignin sulphonate (SLS) with boric acid (BA), thus granting several performance traits like wrinkle-free, antibacterial, flame retardant, UV protection and antioxidant properties. The finished fabric was evaluated for several textile properties like tensile strength, bending length, crease recovery, whiteness index and functional properties like antibacterial activity, UV protection, flame retardancy and antioxidant properties under standard conditions. The finished cotton showed an increase in CRA, antibacterial activity in the range 70-89%, UPF in the excellent range, much higher LOI values with a decrease in heat release and antioxidant activity of higher than 93%. The novel method of multifunctional finishing of cotton by layer-by-layer technique is explored.
采用可持续技术生产的功能改性织物在当今世界需求量巨大。在本研究中，使用壳聚糖在柠檬酸（CS）和木质素磺酸钠（SLS）与硼酸（BA）的溶液中通过逐层两步整理法对棉织物进行改性，从而赋予其多种性能特性，如抗皱、抗菌、阻燃、紫外线防护和抗氧化性能。在标准条件下，对整理后的织物进行了多种纺织性能评估，如拉伸强度、弯曲长度、折皱回复率、白度指数，以及抗菌活性、紫外线防护、阻燃性和抗氧化性能等功能特性评估。整理后的棉织物折皱回复角增加，抗菌活性在70 - 89%范围内，紫外线防护系数处于优异范围，极限氧指数值高得多，热释放减少，抗氧化活性高于93%。探索了通过逐层技术对棉织物进行多功能整理的新方法。
