Abstract

The invention discloses a flame retardation PTT polyester fiber and a preparation method therefor. The flame retardation PTT polyester fiber comprises the following ingredients, by weight, 80%-95% of PTT, 2%-8% of flame retardant monomers, 2%-6% of polyethylene glycol, 0.5%-2% of benzyl silicone, 0.1%-0.5% of potassium Perfluorobutanesulfonate, 0.1%-0.5% of stabilizing agents, 0.1%-0.5% of anti-oxidants and 0.1%-1% of lubricants. The PTT is polytrimethylene terephthalate prepared from terephthalic acid and 1,3-propylene glycol as raw materials and with an intrinsic viscosity of 0.7-0.9dL / g. The flame retardant monomers are 2-hydroxyethyl (phenyl) phosphinic acid. The beneficial effects are that the flame retardation PTT polyester fiber has excellent flame retardation performance and heat resistance, the limit oxygen index can reach more than 38%, the hand feeling is soft, the serviceability is strong, and the flame retardation PTT polyester fiber is suitable for the textile fabric field.
