F. and then cured at about 250.degree.-400.degree. F. for sufficient time to impart smooth-dry and flame retardant properties to said fabric. Aqueous polyethylene or silicone emulsion softeners can be added to the padding solution if desired. Glycol, polyol and dibromoneophentyl glycol make exemplary halogen containing alcohols. The process can also be varied to first pad with antimony oxide, dry, and then repad with a solution of: nitrogen rich N-methylol crosslinking agent, acid catalyst, and a halogen containing alcohol, dry again and cure, at the temperatures specified supra.
