FLAME-RETARDANT FINISHING AGENT FOR POLYESTER-BASED SYNTHETIC FIBER, FLAME-RETARDANT PROCESSING METHOD USING THE SAME AND FLAME-RETARDANT POLYESTER-BASED SYNTHETIC FIBER

摘要

PROBLEM TO BE SOLVED: To obtain a flame-retardant finishing agent for a polyester-based synthetic fiber, which provides a polyester-based synthetic fiber with flame retardance with excellent durability in an increase in the amount of a phosphorus-based flame retardant adhered without impairing a feeling and fastness to friction.;SOLUTION: The flame-retardant finishing agent comprises a water dispersion or a water emulsion containing a diphosphate compound represented by general formula (1) (R¹ and R² are each a lower alkyl group and may be the same or different; R³ and R⁴ are each a hydrogen atom or a lower alkyl group and may be the same or different; n is an integer of 0-4) and triphenyl phosphate solid at a normal temperature. Preferably the flame-retardant finishing agent further contains a tris(alkylphenyl) monophosphate and/or a trialkyl monophosphate liquid at a normal temperature.;COPYRIGHT: (C)2004,JPO&NCIPI
