Preparation method of polyester FDY mother filament and monofilament thereof

[0033] Example 1

[0034] A preparation method of polyester FDY mother yarn. The antibacterial polyester melt containing cuprous material is added to the conventional polyester melt pipeline by means of melt direct spinning pipeline addition, and the static mixer in the melt pipeline After mixing, melt spinning, cooling, drawing, heat setting and winding process to obtain polyester FDY split fiber mother yarn. The specific process is: spinning temperature of 292℃, wind temperature of 16~18℃, wind speed of 0.7~0.85m / s, drawing temperature of 95℃, drawing ratio of 1.8~2.2 times, heat setting temperature of 150℃, winding tension control It is 2.2~2.5cN, and the winding speed is 3900~4500m / min.

[0035] The mass ratio of antibacterial polyester melt containing cuprous material to conventional polyester melt is 1:8;

[0036] The number of holes in the mother yarn spinneret is 6~144 holes, and the denier of the mother yarn is 0.3~20D;

[0037] Monofilament production process: by dividing
