| titleOfInvention | Method for producing hollow fiber membrane for water treatment and hollow fiber membrane for water treatment |
| abstract | In the present invention, the dope solution is radiated with a double tubular nozzle and coated on a support, the polymer component in the dope solution coated on the support is solidified to form a hollow fiber, and then the hollow fiber is washed and dried to form a hollow fiber. In the method for producing a yarn film, the dope solution is a dope solution containing a vinylidene fluoride-based resin and a vinylpyrrolidone-based resin, and a method for producing a hollow fiber membrane for water treatment, and thereby a hollow fiber membrane for water treatment. .n n n The hollow fiber membrane for water treatment produced by the present invention has improved permeability and durability compared to the hollow fiber membrane composed of vinyl fluoride resin alone, and has been applied to the next generation high efficiency separation process industry including highly purified water treatment and water treatment processes. Applicablen n n Hollow fiber, poly (vinylfluoride vinylpyrrolidone) copolymer, vinyl acid |
