| titleOfInvention | Preparation method of hollow fiber pipe in overlay film |
| abstract | The invention discloses a preparation method of a hollow fiber pipe in an overlay film, which comprises the following steps 1) preparing a high-molecular polymer, an organic solvent, an additive and a pore forming agent to a plurality of homogeneous casting solutions according to different proportions; 2) removing the PET fiber braiding tube surface spot objects; 3) using a modifier for modifying the PET fiber braiding pipe, fixing a circular pipe at high temperature; 4) using a multi-immersing multi-rolling (several primary immersing-technology in series) technology for cladding various homogeneous casting solutions to the internal and external walls of the PET fiber braiding pipe in order, carrying out a process of circular pipe heat fixing after each time of immersing and rolling, placing the obtained the composite braiding pipe in a gel bath for splitting the phase after the multi-immersing multi-rolling process is finished to obtain the hollow fiber pipe. According to the invention, the PET fiber braiding pipe is taken as a main body, the multi-immersing multi-rolling technology is used, the micro casting solution is coated to the internal and external walls of the braiding pipe, the anti-pollution capability of the braiding pipe can be improved, and a polymer coat layer is formed on the braiding tube surface which can ensure the effective porosity amount and interception effect of the hollow fiber tube. |
