ABSTRACT:
Polyester/cotton fabrics are flame retardant treated with a flame-retardant cyclic phosphonate ester and tetrakis-(hydroxymethyl)phosphonium sulfate (THPS), usually applied simultaneously, then cured. The resulting fabrics retain their flame-retardant properties after numerous machine washings and have an acceptable hand.
