PURPOSE:To obtain the subject fiber having flame retardancy and excellent softness and smoothness by treating a flame-retardant polyester fiber copolymerized with a specific amount of a specific phosphorus compound with a silicone-based softening and smoothing agent. CONSTITUTION:A polyester fiber for wadding having excellent flame-proofness, etc., is produced from a composition obtained by compounding (A) a flame- retardant polyester fiber containing ethylene terephthalate as the main constituent unit of the fiber and copolymerized with 0.3-1.5wt.% (in terms of phosphorus element) of a phosphorus compound of formula I (R is saturated, open-chain or cyclic alkylene, arylene or aralkylene residue; R1 is 1-6C alkyl, aryl or aralkyl; residues R and/or R1 may contain one or more hetero atoms, especially F, Cl, Br, 0, etc.; R2 and R3 are 1-18C alkyl, aryl or H) with (B) 10-85-wt.% of an aminosiloxane, (C) 10-85wt.% of a terminal-hydroxyl polysiloxane containing hydroxyl group bonded to terminal silicon and (D) 5-25wt.% of an alkoxysilane of formula II (R1 and R2 are alkyl; R3 is alkyl, etc., alkyl substituted with one or more reactive groups, etc.; (n) is 1-3). |
