Abstract
Polyamide and polyester fibers and molding compounds are rendered flame retardant by incorporation into the melt thereof of a complex salt of a polyvalent metal and a hydroxycarboxylic acid, preferably also with boric acid. Preferred complex salts include the subgallates, borocitrates and borotartrates of antimony, aluminum and the alkaline earth metals. The fibers may be tufted to form flame retardant carpets.
