• Glycidyl methacrylate (GMA) was grafted onto polyethylene coated polypropylene nonwoven fibers in emulsion medium by using radiation induced graft polymerization.
• Novel ATZ modified nonwoven fiber was prepared by RIGP.
• Fibers were characterized by FTIR and thermal analysis techniques.
A novel 4-amino-1,2,4-triazole (ATZ) containing nonwoven fiber was prepared by means of radiation induced graft polymerization. For this purpose, glycidyl methacrylate (GMA) was grafted onto polyethylene coated polypropylene nonwoven fibers (NWF) in emulsion medium by using radiation induced graft polymerization. Grafting conditions were optimized and epoxy groups of grafted GMA were then modified with ATZ. Optimum conditions for modification were conducted in different solvents i.e. water and dioxane/water mixture at different amino triazole concentrations (5%, 10%, 20% (w/w)). Maximum modification was obtained in 10% (w/w) ATZ solution in dioxane/water mixture as a solvent at 80 °C. Prepared nonwoven fibers were characterized by FTIR and thermal analysis techniques.
