ABSTRACT:
A breathable flame resistant fabric construction having a pile surface providing desired hand and dyeability, along with the porosity necessary to provide breathability. The fabric construction is formed by bonding flock fibers to the surface of a fiberglass base fabric by means of a polymeric adhesive which in the presence of heat will release flame quenching gases, blocking the flow of oxygen to the normally flammable flock fibers. It has been found that if the base fabric is first coated with a plasticizer before applying the polymeric adhesive, such as employed to secure the flock fibers to the fiberglass, the subsequently applied adhesive will coat the fiberglass yarns constituting the fabric without producing an adhesive film extending over the spaces between yarns, leaving air passing interstices in the fiberglass base fabric, and additionally improve the hand of the base fabric by providing for an increase in "elastic slippage" (i.e. slippage permitting distortion with a subsequent return to original condition) between the yarns making up the base fabric, thus increasing flexibility of the base fabric, and the composite fabric construction.
