Moisture barrier layer with supplemental chemical and biological protective functionality for firefighting clothing applications

Abstract: One of the primary constituent layers of fire protective clothing is a flame-retardant, waterproof and breathable moisture barrier, which permits the outward transfer of perspiration from the firefighter’s body, while barring the inward entry of water. The introduction of a chemical and biological resistant functionality can greatly enhance the overall applicability of fire protective clothing. In the present work, a chemical & biological resistant waterproof breathable flame retardant moisture barrier fab… Show more

“…As expected, coating of the polyurethane on the fabric led to an increase in the amount of hydrostatic pressure which the fabric could withstand, due to the additional reinforcement offered by the woven fabric. In fact the hydrostatic head pressure of BPUx10 coated fabric was found to exceed 3 bar (maximum range of the instrument), which passes even the stringent requirement for the garments used for military and fire protective clothing 27 …”

“…A coated fabric was prepared by transferring a thin film of BPUx10 resin from silicon release paper to a plainwoven blended fabric (70% cotton to 30% polyester) as per the transfer coating procedure reported in our previous work. 26,27 In this method, the chosen resin formulation (BPUx10) was uniformly coated on a silicone release paper (21 cm, 30 cm) using a lab coater machine and the solvent was allowed to evaporate at 80 C resulting in a tacky film. At this point of time, the woven fabric (21 cm, 30 cm) was placed over the polyurethane film and the composite was passed through a roller.…”

“…Aerogel nonwoven fabrics were used as reinforcement materials for waterproof and breathable layers of firefighting suits to reduce the risk of burns, increase comfort, and enhance the protection of the human body [ 22 ]. Activated charcoal fabric as a base fabric laminated with an ePTFE membrane can add chemical and biological protection to the waterproof and breathable layer [ 23 ]. The use of PAN/silica aerogel membranes as a waterproof breathable layer allows for a lighter fabric system with improved wearer mobility and thermal comfort [ 24 ].…”
