Abstract: The present invention relates to a complex hollow fiber for forward osmosis, and a manufacturing method thereof and, specifically, to a complex hollow fiber for forward osmosis, comprising a tubular supporting layer and a separation active layer formed on a concentric circle on the outer periphery of the supporting layer to surround the supporting layer. The separation active layer comprises cellulosic polymers, and the supporting layer comprises non-cellulosic polymers. The hollow fiber has excellent water permeation, mechanical property and pollution resistance, minimizes inner concentration polarization, compared to an existing forward osmosis membrane, maintains the high water permeation, and minimizes solute reverse diffusion of induction solution. In addition, the hollow fiber can be applied to water treatment processes for seawater, salt water, sewage and waste water, especially for a desalination process.
Abstract translation: 本发明涉及一种用于正向渗透的复合中空纤维及其制造方法，具体涉及一种用于正向渗透的复合中空纤维，包括：管状支撑层和形成在外周上的同心圆上的分离活性层 的支撑层以包围支撑层。 分离活性层包含纤维素聚合物，并且支持层包含非纤维素聚合物。 与现有的正向渗透膜相比，中空纤维具有优异的水渗透性，机械性能和耐污染性，使内部浓度极化最小化，保持了高渗透性，并最大限度地减少了感应溶液的溶质反向扩散。 此外，中空纤维可用于海水，盐水，污水和废水的水处理工艺，特别适用于脱盐工艺。
