Polyester fiber having excellent light-shielding and flame retardant characteristic and textile goods using the same

摘要

Disclosed herein is a Polyester Fiber Having Excellent Light-Shielding and Flame Retardant Characteristic. The Polyester Fiber comprises: phosphorus-based flame retardant 0.05˜5% by weight, based on phosphorus atom; and inorganic particles having 0.05˜1 μm average particle size 1-5% by weight, based on fiber weight. Further disclosed is Textile Goods prepared from the Polyester Fiber. The polyester fiber according to the present invention is prepared from polyester polymer having Intrinsic viscosity of 0.55˜0.75 dl/g and the Intrinsic viscosity difference of between the fiber and polymer (IV drop) is within 0.03 dl/g and it exhibits the excellent flame retardant and light shielding characteristic. Therefore, the polyester fiber can be applied to fiber for clothes, light shielding curtain for a car and blackout curtain for a house and theater.
