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

Abstract

A fabric assembly includes a front layer made of a first woven fabric, a back layer made of a second woven fabric, a first interlayer made of a first non-woven fabric, and a second interlayer made of a second non-woven fabric. The first and second interlayers are disposed between the front layer and the back layer, the first interlayer directly contacts the front layer and the second interlayer directly contacts the back layer. The fabric assembly is perfluoroalkyl and polyfluoroalkyl substances (PFAS)-free and has an arc thermal performance value (ATPV) of greater than 39 calories/centimeter square (cal/cm2) when a net weight of the fabric assembly is between about 260 gram/square meter (g/m2) and about 370 g/m2.
