Abstract
A multi-layer protective fabric includes a thin urethane film, a flame-retardant fibrous layer, and a flame-retardant micro-porous layer. The film includes flame retardant additives, blocks a liquid chemical from passing through it, and breathes by an adsorption/de-sorption process to permit water vapor to pass through it. The fibrous layer is bonded on one surface of the film. The urethane layer is bonded on the other surface of the film.
