![]() ![]() In addition, textile combustibility is related to the rate at which the flame is able to propagate. Thus, they can be classified as thermoplastics, which soften and melt above certain temperatures and non-thermoplastics, which tend to carbonize and embrittle at high temperatures. In textile materials, it represents the easiness with which the fabric is capable of being ignited and how effectively it burns, considering that the response to the heat depends mainly on its chemical composition. 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.įlammability is explained by Lewin and Sinclair as the tendency of a material to ignite and burn with a flame creating a fire risk situation. ![]() The highest flame speed was 3.698 ± 1.806 cm/s for the material 67%PES/33%CO, plain weave and filling direction. The lowest flame speed occurred for the material 50% PES/50% WO plain weave and weft direction (0.742 ± 0.140 m/s). The flame speed of each material was determined, and differences in the flame propagation of the fabrics were identified. 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. Five different garments of aeronauts’ uniforms were analyzed (totaling 200 specimens submitted to flammability tests). This study compares the flame speed of different textile materials employed in professional uniforms.
