HEAT INSULATOR FLOOR ANALYSIS IN FIREFIGHTERS' UNIFORM
Abstract
This article provides a scientific analysis of the thermal insulation layer used in firefighter protective clothing. The thermal liner is the primary component that delays heat transfer to the human body under exposure to high temperatures and radiant heat. The structure and fiber chemistry of aramid, PBI, and Nomex-Nano materials are reviewed together with evaluation parameters such as Thermal Protective Performance (TPP) and Moisture Vapor Transmission Rate (MVTR).
