Patent ID: 8449706

Claim:
A process for manufacturing a deaerating hollow fiber module comprising the steps of; wrapping a sheet containing a multiplicity of hollow fibers around a temporary core so that a total area of a membrane of said multiplicity of hollow fibers is within a range from 0.01 m 2 to 0.5 m 2 ; retaining in tubular form said sheet wrapped around said temporary core; supplying a resin to one end of said sheet that is retained in tubular form, bonding the one end of said multiplicity of hollow fibers lined up on the one end of said sheet to each other, and sealing holes of the respective hollow fibers that are open to the one end of said sheet, covering a cylindrical housing over said sheet retained in tubular form before curing of said resin; and removing said temporary core from said sheet covered with said housing after curing of said resin, while retaining said sheet in a tubular form, wherein a deaerating hollow fiber module is formed through said steps such that a filling factor of said multiplicity of hollow fibers in said housing interior is from 5% to 50%.
