Nine 1/1 plain weave fabric samples were developed using various combinations of low-twist ring spun yarns and rovings of FR viscose, p-aramid, and their blends. The three woven combinations were yarn/yarn, yarn/roving, and roving/roving. These fabric samples were compared for mechanical and thermal properties with needle-punched non-woven fabric samples. The radiant heat transfer index (RHTI24) and convective heat transfer index (HTI24) of the woven and non-woven fabrics were determined. In all samples, the HTI24 - HTI12 and RHTI24 - RHTI12 values were more than 4 seconds, which suggested that there was enough time between experiencing pain and sustaining second-degree burns.
