Title:
DEHUMIDIFYING HOLLOW FIBER MEMBRANE, DEHUMIDIFYING MODULE USING SAME, METHOD FOR MANUFACTURING DEHUMIDIFYING HOLLOW FIBER MEMBRANE, AND HUMIDITY-ADJUSTABLE AIR PURIFIER USING HOLLOW FIBER MEMBRANE
Document Type and Number:
WIPO Patent Application WO/2018/230786
Kind Code:
A1
Abstract:
The present invention provides a dehumidifying hollow fiber membrane formed by mixing: one or more first materials having a tubular structure of which both ends are open, and selected from polymers such as polyethersulfone, polysulfone, polyvinylidene fluoride, polyacrylonitrile, cellulose acetate, nylon, polyimide, chlorinated polyvinyl chloride, polyethylene, and polypropylene; and a second material comprising a hydrophilic or water-soluble polymer. With respect to the dehumidifying hollow fiber membrane, a dehumidifying module using the same, and a manufacturing method therefor, the second material comprising a hydrophilic or water-soluble polymer is mixed with the first material for maintaining a tubular structure, and thus gaseous moisture to be dehumidified is diffused onto the entire surface while the gaseous moisture is absorbed, and then is discharged to the outside so as to be removed, thereby improving dehumidification efficiency. The dehumidifying module using the dehumidifying hollow fiber membrane does not require a separate pipeline, thereby having low manufacturing costs, and dehumidification efficiency also becomes excellent while drying gas contact efficiency of the dehumidifying hollow fiber membrane increases.
