ABSTRACT:
This invention relates to a flame retardant for synthetic fiber substrates and a method of imparting flame resistance to such substrates using the flame retardant. The flame retardant of this invention comprises 75 to 95 weight parts of a hexabromocyclododecane compound having a melting point not less than 195.degree. C. and 25 to 5 weight parts of a hexabromocyclododecane compound having a melting point less than 160.degree. C., which hexabromocyclododecane compounds are available on bromination of trans-trans-cis-cyclododecatriene. This flame retardant imparts excellent flame resistance to synthetic fiber substrates. Moreover, when a synthetic fiber substrate is dyed using a dye bath containing this flame retardant and a dye, the soiling of the substrate and dyeing equipment is kept at the minimum.
