PURPOSE:To provide the title flame-retarding processing agent capable of giving synthetic fibers good feel and suitable durability without impairing color fastness, containing a specific phosphoric triester, a dispersant and a protective colloid. CONSTITUTION:The objective flame-retarding processing agent containing (A) a phosphoric triester of pentaerythritol of the formula (X is chlorine or bromine) with three hydroxyl groups in the four hydroxymethyl groups substituted by chlorine or bromine, (B) a dispersant consisting of an ethylene oxide adduct of a fatty acid alcohol etc., and (C) a protective colloid such as PVA. A synthetic fiber, esp. polyester- or polyamide fiber product is imparted with this agent followed by drying and then heat treatment at 170-220 deg.C. Said agent is especially suitable for polyester and polyamide synthetic fibers, and does not impair their color fastness. The fiber products treated with this agent are good in feel and excellent in resistance to domestic washing and dry cleaning. |
