<p>A polyvinylidene fluoride hollow fiber membrane and process for producing the same. The starting materials comprise 20~60% by weight of polyvinylidene fluoride resin, 10~50% by weight of organic pore former, 1~30% by weight of inorganic pore former and 5~30% by weight of solvent. The process comprises blending and extruding, cooling, stretching, extracting organic pore former and inorganic pore former, and heat setting treating. The obtained polyvinylidene fluoride hollow fiber membrane has high strength, excellent performance and good hydrophilicity. The producing process flow is simple and energy saving.</p> |
