Durability of Biocidal Nomex Fabrics for Multi-functional Firefighter Uniforms

Abstract

Nomex IIIa fabrics can easily acquire biocidal properties by chlorination in chlorine bleach. Durability of the biocidal fabrics was investigated. Results indicate no significant mechanical property differences between control and treated fabrics that have undergone identical long-term UV and radiant heat exposure, weathering, and laundering cycles. Furthermore, reductions of active chlorine concentration on fabrics attributed to long term environmental challenges can be recovered in most cases via recharge of chlorine during subsequent laundering cycles. The results of this study suggest that direct chlorination of Nomex IIIa can be used to impart biocidal efficacy onto the fabrics without degradation of the polymer.
