Background

The ultrafiltration membrane is a polymeric semipermeable membrane capable of separating polymeric colloid or suspended particles with a certain size from a solution, and consists of thousands of membrane filaments, wherein the membrane filaments are usually composed of cellulose acetate, polyacrylonitrile, polysulfone or fluorine resin and the like. In the process of manufacturing the membrane yarn, first, a hydrophobic polymer and a hydrophilic polymer are dissolved in a membrane-making dope. The hydrophilic polymer is a polymer in which the viscosity of a film-forming solution is adjusted to a range suitable for forming a film yarn, and in order to stabilize the film-forming state, polyvinyl glycol, polyvinyl pyrrolidone, or the like is often used. In contrast, a solvent is often used which can dissolve the hydrophobic polymer and the hydrophilic polymer and is soluble in water, such as N, N-dimethylacetamide (DMAc) and N, N-Dimethylformamide (DMF).

The membrane yarn produced by the above method often has a large amount of solvent and hydrophilic polymer remaining in a solution state. If the solvent remains in the membrane filaments, the membrane filaments are swollen, and the mechanical strength of the membrane filaments is lowered, and if the hydrophilic polymer remains in the membrane filaments, the water permeability of the membrane filaments is lowered. Therefore, after the membrane filaments are made, the membrane filaments must be washed to remove the solvent and the hydrophilic polymer.
