This invention relates to fire retardant latex binders for non-woven fabrics. Non-woven fabrics can be manufactured using the fire retardant latex binder formulations of this invention using cotton fibers, polyester fibers, rayon fibers, nylon fibers, cellulosic fibers, fiber glass or various mixtures of such fibers. The fire retardant latex binders of this invention are particularly useful in manufacturing fiber glass furnace filters. The fire retardant latex binders of this invention are comprised of (1) water, (2) a styrene-butadiene rubber, (3) a fatty acid soap, (4) a sulfonate surfactant, (5) an ethylene oxide/propylene oxide/ethylene oxide triblock polymer, wherein the ethylene oxide/propylene oxide/ethylene oxide triblock polymer has a number average molecular weight of at least 8000, and (6) about 10 phr to about 50 phr of diammonium phosphate.
