Rahel Heesemann, Sudhanshu Maurya, Rochak Rathour, Apurba Das, Thomas Gries
TL;DR
This paper investigates fabric weaves for firefighter clothing to improve comfort and protection against cuts and stabs.
Contribution
The study introduces new fabric weaves that enhance air permeability and protection in firefighter gear.
Findings
Honeycomb and Huck-a-back weaves outperform the standard Twill 2/2 weave in breathability and protection.
Improved air permeability helps reduce heat load and enhances sweat transport in firefighter clothing.
Abstract
Firefighter protective clothing is composed of multiple layers, each serving distinct functions. The outer layer shields the user from fire, chemicals, cuts, body fluids, and water, while also permitting water vapour to escape. The middle membrane layer acts as a thermal and moisture barrier, preventing heat and liquid penetration but allowing vapour diffusion. The inner layer enhances thermal protection and wearer comfort. A nationwide German survey and risk analysis with different fire brigades identified a need for enhanced comfort, reduced physiological heat load, and improved protection against stabs and cuts. Enhanced tear resistance is one proposed method for increased stab and cut protection. Wearer comfort parameters include water vapour permeability, breathability, air permeability, efficient cooling and increased breathability of the protective clothing are crucial for…
