Abstract:
A yarn, fabric, and garment suitable for use in arc and flame protection comprising aramid fiber and modacrylic fiber wherein the modacrylic fiber has less than 1.5 percent antimony and is preferably antimony-free. In one embodiment, the yarn, fabric, and/or garments consist essentially of (a) 50 to 80 weight percent meta-aramid fiber having a degree of crystallinity of at least 20%, (b) 10 to 40 weight percent modacrylic fiber that is antimony-free, (c) 5 to 20 weight percent para-aramid fiber, and (d) 1 to 3 weight percent antistatic fiber, based on the total weight of components (a), (b), (c) and (d). In some embodiments, garments made from the yarns provide thermal protection such that a wearer would experience less than a 65 percent predicted body burn when exposed to a flash fire exposure of 4 seconds per ASTM F1930, while maintaining a Category 2 arc rating per ASTM F1959 and NFPA 70E.
