    • PROBLEM TO BE SOLVED: To provide a rubbing cloth having all characteristics of high abrasion resistance, low antistatic properties, large orientation-restraining force and forming almost no scratch on an orientation membrane at rubbing.
      SOLUTION: The rubbing cloth for the orientation treatment contains a cellulose ester fiber which is a cellulose acetate propionate and/or cellulose acetate butyrate satisfying the following expressions (I) and (II): (I) 2.8≥DS
      ace +DS
      acy ≥2.0; and (II) 0.9>DS
      ace /(DS
      ace +DS
      acy )>0.5 (wherein, DS
      ace is an acetyl group substitution degree of a hydroxy group in the cellulose ester; and DS
      acy is the sum of a propionyl group substitution degree and a butyl group substitution degree of the hydroxy group in the cellulose ester).

    • PROBLEM TO BE SOLVED: To provide a method for producing a hollow fiber membrane for blood purification, which is excellent thread sliding property and to provide a hollow fiber membrane excellent in spinning yield and module production yield.
      SOLUTION: In the hollow fiber membrane for blood purification, a coefficient of static friction and a coefficient of kinetic friction between hollow fiber membranes are within a predetermined range. In the method for producing a hollow fiber membrane for blood purification, a hollow fiber membrane is produced by dry-wet spinning method. In the method, drying and cooling steps are carried out just before winding the hollow fiber membrane around a bobbin.
