SITEX 05 ( Design and Development of Extreme Heat Protective Clothing for Defense Application )

The developed jacket is a multilayered arrangement consisting of four layers namely outer shell, moisture barrier, thermal liner, and face fabric. The outer shell of the jacket is made of aramid woven fabric that provides high flame retardancy, heat resistance, and breaking strength. It is dimensionally stable and durable. PU-coated PTFE laminated meta-aramid nonwoven fabric is used as a moisture barrier for the jacket. Meta-aramid needle-punched nonwoven fabric is used as a thermal liner in the jacket. The thermal liner is divided into various layers of different areal densities to achieve better insulation. A face fabric made up of twill weave cotton fabric is also placed after the thermal liner in the jacket to provide tactile comfort to the wearer. The jacket provides a TPP rating of 38 cal/cm2.sec for the given exposure conditions as per NFPA standards. The weight of the jacket is 2.2 kg (approximate). Salient Features: • Indigenous • Lightweight • Modular design: four garment layers • Proven Performance: Rigorously tested to meet functional standards.
