Abstract
The laminate is formed of a sheet of a woven textile material derived from multifilamentary aramid, polyimide, polyamide, polybenzimidazole or cellulose fire retardant yarns and a sheet of non-woven textile material. The adhesive used to produce the laminate should prevent slippage of the two materials relative to one another and fraying of the woven textile material while enabling the laminate to be air permeable, and having a minimum ten (10) cubic feet per minute (CFM) when tested in accordance with test method ASTM D737. This product is cheaper to manufacture and is more comfortable than the known quilted and coated material.
