The influence of textile materials on flame resistance ratings of professional uniforms
This study compares the flame speed of different textile materials employed in professional uniforms. Five different garments
of aeronauts’ uniforms were analyzed (totaling 200 specimens submitted to flammability tests). Plain weaves and
twill weaves composed by 100% CO; 100% PES; 67% PES/33% CO; 50% PES/50% WO; and 55% PES/45%WO were analyzed
in the warp and filling directions. The flame speed of each material was determined, and differences in the flame propagation
of the fabrics were identified. The lowest flame speed occurred for the material 50% PES/50% WO plain weave and
weft direction (0.742 ± 0.140 m/s). The highest flame speed was 3.698 ± 1.806 cm/s for the material 67%PES/33%CO, plain
weave and filling direction. Future experiments for reducing the fabric flammability of the uniforms could be related to
more closed fabric constructions; mixtures with synthetic fibers to add functionality; changing the direction of the fabric;
and changing the weight and torsion of its constituent yarns.São Paulo Research Foundation—FAPESP (“Fundação de Amparo à Pesquisa do Estado de São Paulo”) Grant Number 2016/01331-
