| titleOfInvention | Polyvinylidene fluoride resin hollow filament microfilter and process for producing same |
| abstract | A screen type hollow filament microfilter with a double layer structure of a skin layer and support layer, which comprises polyvinylidene fluoride resin hollow filament, which facilitates adjustment of pore size of interior and exterior surface skin layers of the resin film with a large effective average pore size of 0.05 to 1.0 (Alpha)m, which has a highly selective permeability, a large amount of permeation, a large void, and excellent mechanical strength, chemical resistance, and inert properties against living organisms. This microfilter with various excellent properties can be produced by extruding a spinning solution containing a polyvinylidene fluoride resin, a solvent for the resin, and at least one surfactant through a ring orifice, and coagulating using a coagulating solution. |
