    Abstract: A hollow-fiber porous membrane of vinylidene fluoride resin, satisfying: a ratio Pmax/Pm of at most 2.0 between a maximum pore size Pmax and an average pore size Pm, and a Pm of 0.13 μm-0.25 μm, according to the half-dry/bubble point method (ASTM F316 and ASTM E1294); a coefficient of variation in outer surface pore size of at most 70%, and a porosity of 75-90%. The hollow-fiber porous membrane has a moderate average pore size, has a pore size distribution which is uniform as a whole and also on the outer surface, and has a high porosity, so that it shows not only a good pure water permeability but also retains a good water permeability even in continuous filtration of cloudy water. The hollow-fiber porous membrane is produced through a process which includes: melt-extruding a vinylidene fluoride resin together with a plasticizer and a good solvent therefor into a hollow-fiber film, cooling and solidifying the film, extracting the plasticizer and good solvent, omitting a heat-treatment for crystallization, and stretching the hollow-fiber after the extraction at a limited temperature range of 80-95° C. which is higher than a conventional stretching temperature.

    Abstract: A porous membrane of vinylidene fluoride resin, having two major surfaces sandwiching a certain thickness, including a dense layer which governs filtration performance on the one major surface side and a sparse layer which contributes to reinforcement on the other opposite major surface side, and having an asymmetrical gradient network texture including pore sizes which increase continuously from the one major surface to the other opposite major surface, wherein the dense layer includes a 7 μm-thick portion contiguous to the one major surface showing a porosity A1 of at least 50%, and the one major surface shows a pore size of at most 0.30 μm. The vinylidene-fluoride-resin porous membrane is generally useful as a porous membrane for separation and particularly exhibits good water-permeation-rate retentivity even in continuous filtration of cloudy water. The vinylidene-fluoride-resin porous membrane is produced by a process including: melt-extrusion of a composition obtained by adding to vinylidene fluoride resin of a large molecular weight a relatively large amount of a polyester plasticizer which is mutually soluble with the resin and provides the resultant mixture with a crystallization temperature that is substantially identical to that of the vinylidene fluoride resin alone to form film, followed by cooling from one side of the film to solidify the film and extracting the plasticizer.

    Abstract: A hollow-fiber porous membrane, comprising a hollow fiber-form porous membrane of vinylidene fluoride resin providing: a ratio F (L=200 mm, v=70%)/Pm4 of at least 7×105 (m/day·μm4), wherein the ratio F (L=200 mm, v=70%)/Pm4 denotes a ratio between F (L=200 mm, v=70%) which is a value normalized to a porosity v=70% of a water permeation rate F (100 kPa, L=200 mm) measured at a test length L=200 mm under the conditions of a pressure difference of 100 kPa and a water temperature of 25° C. and a 4-th order value Pm4 of an average pore size Pm. The hollow-fiber porous membrane has an average pore size smaller than before leading to an improved ability of removing fine particles, while suppressing the lowering in water permeability. The hollow-fiber porous membrane is produced by melt-extrusion and low-temperature cooling of a starting composition including a resin material containing an ultra-high molecular weight resin component in a larger amount than before, and increased amounts of plasticizer and good solvent.
