The purpose of the present invention is to provide a synthetic fiber which is for use in fabrics having uniform fiber density, permeability and the like, is appropriate for high-density, high-speed weaving, and exhibits excellent weft insertion stability. This synthetic fiber is characterized by having: a fiber density of 200-720 dtex; an average intermediate loading modulus of more than 75 cN/dtex and less than 150 cN/dtex; and a variation coefficient of the intermediate modulus of 5% or less. |
