[0033] figure 1 It is the process flow chart of the preparation method of composite monofilament applied to filter material base cloth provided by the present invention; as shown in the figure, the preparation method of composite monofilament applied to filter material base cloth provided by the present invention includes:
[0034] (1) The PET chips mixed with nano-calcium carbonate are dried, screw melted, spinning, stretched and shaped, and ultrasonically cleaned into a core layer monofilament;
[0035] (2) PE chips mixed with LPET are dried and screw melted to form a skin layer;
[0036] (3) The core layer monofilament and skin layer produced in step (1) and step (2) are composited and spun, and then cooled in a water bath, and finally wound and formed into composite monofilament for filter base fabric .
[0037] Among them, in step (1), 8%-15% of nano-calcium carbonate is mixed in PET; during drying treatment, pre-crystallization: 45-80°C (1 to 4 hours), heating: 81-125°C (1~ 6 ...
