Abstract
Novel flame retardant finishes comprising a water soluble quaternary phosphonium salt, a water soluble organic nitrogen containing compound, a phosphate ester of haloalkanols, an emulsifying agent which is capable of passing the following three tests: (1) Solubility (Compatability) Test: said emulsifying agent (20 parts by weight) must be soluble in 80 parts by weight of said phosphate ester at less than or equal to 80.degree. C.; (2) Shelf Life Test: a blend of said emulsifying agent and said phosphate ester prepared as in the Solubility Test must remain in one clear homogeneous phase at 22.degree. C. for at least one hour; (3) Finish Formulation Test: a flame retardant finish within the scope of this invention is prepared and must remain in one homogeneous phase for a minimum of 1 hour at 20.degree. C., and water. These flame retardant finishes are excellent for flame retarding textile materials including polyester/cotton blend fabrics.
