ABSTRACT:
The disclosure relates to a new and improved method of enhancing the fastness of the flame resistance properties imparted to wool by depositing a halophthalic acid derivative on the wool from an aqueous medium and which involves aftertreating such derivative-treated wool product with a fastening agent adapted to fix said derivative on the wool and thereby increase the fastness of the flame resistance properties to wet treatments and dry cleaning.
