PURPOSE:To obtain natural and synthetic polyamide fibers with excellent wash resisting antiflaming property, by treating them with a specific treating agent. CONSTITUTION:Natural and synthetic polyamide fibers are treated with an aqeous acid solution consisting of a treating solution containing a substituted phthalic acid with one or more chlorine or bromine atoms and its derivatives, together with a chromium compound (for example: bichromates), and an added inorganic acid (or an organic acid); or first treated with an aqueous acid solution of a halogenated phthalic acid, and then treated with an aqueous acid solution containing the chromium compound (or visa versa) to give excellent wash resisting antiflaming property. |
