Hollow fiber tube and aeration oxygenation device formed by hollow fiber tube

The invention relates to a hollow fiber tube. The hollow fiber tube is woven by superfine fiber yarns with thickness of 0.001-0.01D and/or fiber bundles formed by the superfine fiber yarns; a plurality of flexible holes are formed in the tube wall of the hollow fiber tube obtained by weaving, wherein the flexible holes are formed by arranging the fiber yarn, the fiber bundle, the fiber yarn and the fiber bundle in parallel and/or crossing and superposing in a weaving process; the hole diameter of the flexible holes can be changed between 1 micro and 30 microns along with the difference of air pressure. The invention further discloses an aeration oxygenation device formed by the hollow fiber tube. The device has the remarkable advantages of high oxygen utilization rate (up to 25-40%), difficult block, high mechanical strength, long service life, convenient manufacturing, low cost and the like, and can be widely applied to the aeration oxygenation occasions of the fields such as chemical industry, environmental protection and fishery breeding.
