    Abstract: The present invention relates to a preparation method of a hollow fiber membrane for water treatment, wherein the hollow fiber membrane is prepared by preparing a spinning composition comprising a cellulose-based resin, a poor solvent, a plasticizer and an organic solvent, and spinning the spinning composition to a non-solvent. The present invention makes up for shortcomings of conventional preparation methods of a hollow fiber membrane, that is, can easily increase the physical properties of a separator for water treatment, shows easy reproducibility, and can provide a nanofilter (NF) and a reverse osmosis (RO) hollow fiber membrane for water treatment capable of obtaining high efficiency with a low cost.

    Abstract translation: 本发明涉及一种水处理用中空纤维膜的制造方法,其中,中空纤维膜是通过制备含有纤维素类树脂,不良溶剂,增塑剂和有机溶剂的纺丝用组合物而制备的, 将组合物纺丝成非溶剂。 本发明弥补了传统中空纤维膜制备方法的缺点,即可以容易地增加水处理用隔膜的物理性质,显示出容易的再现性,并且可以提供纳米过滤器(NF)和反渗透( RO)用于水处理的中空纤维膜,能够以低成本获得高效率。
