PROBLEM TO BE SOLVED: To obtain a dyed fabric having high hydrophilicity and its durability and increases color deepening and color darkening of dyed material and to provide a method for producing the same. SOLUTION: The dyed fabric exhibits hydrophilicity having wet tension≥10mN/m higher than a dyed fabric before plasma treatment and maintaining its value for one week or more. The method for producing the dyed fabric comprises carrying out surface treatment of a predyed fabric (1) by using an open type plasma apparatus which has an electric energy per unit area of≥400W×minute/m<SP>2</SP>, has a normal temperature and a normal pressure, comprises cathode drums (3, 11) and a plurality of ceramic-covered anode bars (4a-4c, 12a-12c) arranged in the direction perpendicular to the traveling direction of a fabric above the surfaces of the cathode drums and generates a plasma by corona electric discharge from the anode bars in the direction of the cathode drums.
