| titleOfInvention | Cellulose derivative hollow fiber membrane |
| abstract | PROBLEM TO BE SOLVED: To provide a cellulose derivative hollow fiber membrane having high mechanical strength, low biodegradability and high permeation flux. SOLUTION: This is a hollow fiber membrane using a cellulose derivative as a membrane material, having a thickness of 50 to 500 µm, and having a dense membrane surface having an average pore diameter of 0.001 to 0.05 µm on at least one of the inner and outer surfaces. The average pore size inside the membrane is 0.5 to 7 The three-dimensional mesh-like porous structure having pores of μm has at least one maximum value in the pore size distribution of the three-dimensional mesh-like porous structure inside the membrane, and the maximum value is 8 μm The cellulose derivative hollow fiber membrane described above, wherein 70% by mass or more of the membrane material is cellulose acetate propionate or cellulose acetate butyrate. |
