Research on Thermal Properties of Nomex Fiber and Nomex/Viscose Blended Fabric

Based on the analysis of the properties of Nomex 450 and Nomex 462, the thermal properties of Nomex 462/ Lenzing Viscose Flame retardent （FR） blending materials were analyzed. It was discovered through burning test and Thermal Gravity （TG） analysis that the blended material was superior in thermal behaviors to the material made from either Nomex or Viscose FR filament, when the ratio of Nomex and Lenzing Viscose FR reached 80 ： 20, and excellent thermal properties were achieved with the value of Limiting Oxygen Index （LOI） up to 36. 1%. Blending Nomex and Viscose FR filaments may be recommended for better fire retardant property of related fabric.
