Abstract: Relatively lightweight laminate structures having an outer textile layer, a heat reactive material, a middle layer, a flame retardant adhesive material and an inner layer, wherein the flame retardant adhesive material is positioned in a pattern so as to form a plurality of pockets, each of the pockets defined by (a) the middle layer, (b) the inner layer, and (c) a portion of the flame retardant adhesive material. The laminate structures can provide protection from an exposure to an electrical arc.

Abstract: A flame protective fabric structure (1) comprises a fabric (10) being formed with multiple yarns (20), each yarn (20) made of a fiber blend of at least a first fiber component and a second fiber component. The first fiber component comprises flame resistant viscose fibers (22) in an amount of at least 50% of the fiber blend weight and the second fiber component comprises meltable fibers (24) in an amount of at least 10% of the fiber blend weight. The fabric (10) is formed as a woven fabric with a total fractional cover factor of greater than 60% having a capability to withstand a horizontal flame exposure of 10 seconds without hole formation according to ISO 15025/14116_Index III.
