PREPARATION METHOD OF HOLLOW FIBER MEMBRANE FOR WATER TREATMENT USING CELLULOSE-BASED RESIN

摘要

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.
