Journal Textile Coloration and Finishing Year / Vol., Issue, Month 2021 / V.33,no.4,Dec Title Flame Retardant Properties of Cotton Fiber with Phosphoric/citric Acid Catalysts and TiO2 Authors Heejin Yang, Samsoo Kim, Sangoh Lee1, and Jaewoong Lee* Institution/Affiliations Yeungnam University Pages/Total page pp.238 ~ 249 / 12 Language Korean Abstract In this study, the effect on flame retardancy and various physical properties when TiO2 was added with a citric acid/phosphate complex acid catalyst together with Pyrovatex CP new (N-methylol dimethylphosphonopropionamide), a phosphorus-based flame retardant, was studied on cotton fibers. SEM-EDS analysis was performed to confirm the surface characteristics and surface element analysis of the flame-retardant treated cotton fibers, and a vertical carbonization test was performed to confirm the char formation capability and flame retardancy according to the phosphoric acid ratio. By comparing the LOI index before and after washing 10 times, the washing durability of the flame retardant solution containing the phosphoric acid catalyst and TiO2 was tested by LOI index after ten washing cycles. In addition, the influence of the flame-retardant processing on the physical properties were compared including thermogravimetric analysis (TGA), tear strength and whiteness.
