Abstract: The present invention relates to a method for measuring a mixing rate of polyethyleneterephthalate (PET) and polytrimethyleneterephthalate (PTT) fibers. The method comprises a qualitative analysis step of checking the existence of PET and PTT fibers in a fiber blend and a quantitative analysis step of measuring a mixing rate using a microscopic count method through the color difference between the PET and PTT fibers caused by double refraction in a cross polarization state of a polarized light microscope (PLM). Thus, the present invention can conveniently and precisely calculate the mixing rate of the PET and PTT fibers in the fiber blend in which various fibers are mixed.
