A hollow fiber membrane fluid transport device is disclosed wherein the fibers are comprised of Polytetrafluoroethylene (PTFE), and the potting materials are comprised of fluorocopolymer and or fluoroterpolymer based materials. The potting of the device utilizes a compressed chemically resistant fluorocopolymer and or fluoroterpolymer film, allows for ease of manufacture without destruction of the PTFE hollow fibers, with high packing densities, and without the processing complexity of pre-melting, extruding, or chemical crosslinking of any polymeric adhesives. Furthermore, the PTFE hollow fibers can be treated with a fluoropolymeric solvent solution before the chemically resistant film is applied to enhance the adhesion of the PTFE fiber to the film. PTFE hollow fibers, and its respective fluoro-co and terpolymers as potting films impart high packing densities, superb chemical resistance and temperature resistance without membrane contamination, or low fiber pull strength, as is sometimes observed with standard potting materials such as polyurethane and epoxy.

A filter core and manufacturing method thereof, the manufacturing method has the following steps: adhering a wavy filtering sheet and a flat filtering sheet, pressing the filtering sheets, and rolling the filtering sheets. A part of peaks of the wavy filtering sheet are pressed to lean toward a same side. In particular, two sides of a first end sealing adhesive layer are pressed. Thus, the first end sealing adhesive layer is concentrated, such that the glue is uniformly spread to the two sides. Besides, the pressing on the two sides makes the two sides of the first end sealing adhesive layer adhered securely, thereby preventing the wavy filtering sheet from rebounding upward and forming bubbles. Thus, the first end sealing adhesive layer can be formed with less quantity of glue, which accelerating the cooling and raises manufacture efficiency.
