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.COPYRIGHT: (C)2008,JPO&INPIT【課題】糸すべり性が高い血液浄化用中空糸膜の製造方法を確立することにより、該中空糸膜の紡糸やモジュール作製歩留まりの高い中空糸膜に関するものである。【解決手段】中空糸膜対中空糸膜の静止摩擦係数と動摩擦係数が一定範囲内にある血液浄化用中空糸膜。また、乾湿式紡糸法による中空糸膜の製造において、中空糸膜をボビン形に捲き取る直前に、乾燥と冷却工程を実施する血液浄化用中空糸膜の製造方法。【選択図】なし
