Flame retardant properties of fabrics designed to be used in militarycamouflage

In this study, wool/aramid blended yarns, as well as viscose FR yarns, were used to produce flame-retardant woven fabrics. Many fire retardancy standards also include tear strength, abrasion resistance, tensile strength and dimensional change of the fabrics during fire hazards. Therefore, these tests were included to study the fire retardant performances of the fabrics produced with 100% wool/aramid blended fibres and viscose FR fibres in the warp and wool/aramid blended fibres in the weft direction. As a result of the study, no statistically significant differences were found in the mechanical properties of the fabrics. In contrast, the thermal protective performance of the fabrics produced with wool/aramid blended yarns was better than the ones produced with viscose FR warp yarns. On the other hand, the vertical flame-retardant performance of fabrics produced with viscose FR yarns was better than those produced with wool/aramid blended yarns in both directions. As a result of the study, it was found that the use of viscose FR fibre, which is a more accessible and comfortable alternative to the wool/aramid blend, in the warp or weft direction will minimize fabric costs while providing similar flame-retardant performance without losing fabric mechanical properties.
