The Effects of Batting Materials on the Performance of Turnout Thermal Liners

Abstract

The effects of fiber and constructional variables on the properties of hydroentangled nonwovens important to their performance when used as batting components in firefighter turnout systems are investigated. Para-aramid, meta-aramid and oxidized PAN constructions are characterized on the basis of thermal insulation, flexibility and durability performance. The contribution of batting properties to the thermal protective performance provided by multilayer turnout systems is examined for selected turnout lay ups. Optimized thermal liner systems are suggested based on layered constructions including the properties of the face cloth components.
