Abstract
Synthetic-cellulosic blended fabric is padded with a solution of nitrogen rich N-methylol crosslinking agent, acid catalyst, antimony oxide and a halogen containing alcohol; dried at about 140.degree.-190.degree. F. and then cured at about 250.degree.-400.degree. F. for sufficient time to impart smooth-dry and flame retardant properties to the fabric. Aqueous polyethylene or silicone emulsion softeners can be added to the padding solution if desired. Dibromoneopentyl glycol makes an exemplary halogen containing alcohol. The process can 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 above specified temperatures.
