Lightweight, flame resistant fabrics protective against arc flash and thermal performance

Abstract

A fabric includes flame-resistant Rayon fiber, about 10% by weight to about 20% by weight, based on an effective fabric blend; and oxidized polyacrylonitrile fiber, about 5% by weight to about 15% by weight, based on the effective fabric blend. The fabric includes para-aramid, about 5% by weight to about 15% by weight, based on the effective fabric blend; and nylon fiber, greater than about 0% by weight to about 15% by weight, based on the effective fabric blend. The fabric also includes anti-static fiber, less than 2% by weight, based on the effective fabric blend; and meta-aramid fiber, about 44% by weight to about 80% by weight, based on the effective fabric blend. The fabric has a basis weight of less than about 6.5 oz/yd2 or 220.39 g/m2.
