| 20090317631 | Braid-reinforced hollow fiber membrane - Disclosed herein is a braid-reinforced hollow fiber membrane, comprising an active layer formed on the surface of a tubular braid, wherein the braid is made of a mixture of metal wire with polymer fiber. The hollow fiber membrane can be used in separation processes at high pressure due to the pressure resistance thereof, can be used in the separation of organic solvents at high temperature due to the dimensional stability thereof, and in addition, can be used in various applications due to the electrical conductivity thereof. | 12-24-2009 |
| 20090314708 | Hollow fiber membrane for feeding mixture into hollow space thereof - Disclosed herein is a hollow fiber membrane for feeding a mixture into the hollow space thereof, in which the mixture to be separated is fed into the hollow space of the hollow fiber membrane and allowed to permeate through a porous membrane comprising an active layer. The hollow fiber membrane is manufactured by forming a tubular active layer having a hollow space and making a polymer fiber braid, a metal wire braid or a braid consisting of a mixture of polymer fiber with metal wire, directly on the outer surface of the tubular layer, such that the active layer can be prevented from being expanded if a high-temperature, high-pressure mixture is fed into the hollow space. | 12-24-2009 |
