[0002] Polyester is the trade name of polyester fiber in my country. ITY is a composite of FDY and POY.

[0003] In the production process of polyester composite yarn, the polyester melt after esterification and polycondensation is generally pressurized by a booster pump, cooled by a melt cooler, distributed to each spinning box through a barrel, and then quantitatively fed into the assembly by a metering pump. After being filtered by the assembly, it flows out from the spinneret hole through extrusion, and then solidified into fiber after cooling. The ITY composite yarn is composed of POY spun from the A side and FDY spun from the B side, which are compounded after winding the oil nozzle. The spinneret is a key part of the spinning process. The arrangement of the spinneret holes and the spacing of the holes used in the prior art, when the ring blowing is used to cool the spinneret holes, the monofilaments are prone to cross and stick when the cooling wind blows over. When the cooling wind pressure is reduced, the penetration performance of the cooling wind is poor, the solidification point is greatly offset, the monofilaments are unevenly cooled, and it is easy to cause the strands to break.
