Provided are a composite polyester material, a polyester fibre, a preparation method therefor and a use thereof. Both the polyester material and the polyester fibre contain a complex having a carbon nanostructure. The complex having a carbon nanostructure contains the element carbon, 0.5-4 wt% of a first element, being neither carbon nor oxygen, and 0-4 wt% of a second element, being neither carbon nor oxygen. The first element, being neither carbon nor oxygen, is P, Si, Ca, Al and Na, and the second element, being neither carbon nor oxygen, is selected from any one or a combination of at least two of Fe, Ni, Mn, K, Mg, Cr, S or Co. In a Raman spectrum, the peak height ratio of a G peak to D peak of the element carbon of the complex having a carbon nanostructure is 1-20. By selecting a complex having a specific carbon nanostructure to composite with a polyester material and a polyester fibre, better anti-microbial and low-temperature far-infrared properties are achieved. Also, the provided method for preparing the polyester material composited by the complex having a carbon nanostructure is simple.
