METHOD FOR CARRYING OUT FLAME PROOF FINISH OF POLYESTER-BASED SYNTHETIC FIBER AND POLYESTER-BASED SYNTHETIC FIBER TO WHICH FLAME PROOF FINISH IS APPLIED

摘要

PROBLEM TO BE SOLVED: To provide a method for carrying out flame proof finish in which flame proof finish is applied to a polyester-based fiber in good efficiency in post processing by using a compound not containing a halogen atom.;SOLUTION: In the method for carrying out flame proof finish of the polyester-based synthetic fiber by a treating solution (I) containing a flame retardant (A) composed of one or more kinds of organophosphorus-based compound (a), a zeta potential of the treating solution (I) is controlled to -20 to -80 mv and the organophosphorus-based compound (a) is dispersed into the treating solution (I) as fine particles having ≤2 μm average particle diameter.;COPYRIGHT: (C)2004,JPO&NCIPI
