Abstract
The present invention relates to a method for producing a multifunctional polyester fiber, including: mixing a polyester master batch chip, containing cesium tungsten oxide-based particles, with a general polyester chip; spinning the mixture to form a spun fiber; and cooling the spun fiber using a cooling device having a rotational outflow quenching unit and a nozzle-warming heater, and to a fiber produced by the method. The multifunctional polyester fiber according to the present invention exhibits excellent far-infrared emission properties, thermal storage/insulation properties, spinning processability, and dyeability.
