A polyethylene terephthalate bulked continuous filament is prepared by a method comprising a step of melt-spinning and multi-stage stretching polyethylene terephthalate chips and coloring master batch chips and causing the resultant product to pass through a texturing nozzle, followed by cooling and winding, and may have an elastic modulus of 1.00E + 07 to 5.00E + 09 Pa in a temperature range of 10 to 200°C. In the polyethylene terephthalate bulked continuous filament of the present invention, the elastic modulus is improved compared to the prior art, and thus an elastic recovery rate can be improved.
