[0043] When implementing:

[0044] First, the spinneret body is connected to the bottom of the polymerization kettle 4 through its flange part 2. Ensure that the flange part 2 is tightly fitted with the flange structure 9 at the bottom of the polymerization kettle 4 and fixed by bolts to form a preliminary sealing structure. At the same time, the guide tube part 3 is inserted into the opening at the bottom of the polymerization kettle 4.
