Functionalization of linen fabric using layer by layer treatment with chitosan and green tea extract

Development of multifunctional textile materials using green chemicals is a new quest of research. In the present work, the LBL treatment using chitosan (CH) and green tea extract (GTE) was utilized for the functionalization of linen fabric. The functionalized linen was characterized and functional properties of the modified linen viz. antioxidant property, antibacterial activity and UV protection were evaluated. The LBL finishing resulted in the coloured linen fabrics with antibacterial activity in the range 75-97%. Moreover, the treated fabrics also displayed an antioxidant property (58-96%) and the ultraviolet protection property (UPF> 22.5). The synergistic influence of CH and GTE was witnessed in imparting vital functional properties to linen using LBL technique. (C) 2019 The Korean Society of Industrial and Engineering Chemistry.
