In the actual production process, melt is injected into the spinneret assembly 10 at the top of the spinning box 13 through the booster pump, and then a plurality of monofilament fibers are downwards ejected through the spinneret holes 11 and form tows into the TMT winder 1, because the spinneret holes 11 used in the common POY polyester yarn production line are round holes, the conventional round section fibers have poor waterproof effect after forming tows due to larger gaps between the round holes, so that the filament outlet holes in the spinneret holes 11 are designed into a starfish structure in order to meet the characteristic of high waterproof performance of the fiber tows, thereby forming starfish-shaped forming holes 12, enabling the section of each monofilament fiber to be of the starfish structure, and enabling the monofilament fibers and the monofilament fibers to be staggered, so that the monofilament fibers and the monofilament fibers are more compact, and form a dense weaving form after being oiled, so that the fabric woven by the tows has a lotus leaf effect, has a high waterproof effect without special process treatment, and meanwhile, the fabric is softer and has the unique skin, and the cost is saved for the subsequent processing.

Further, as shown in fig. 2, the spinneret hole 11 is composed of three layers of the starfish-shaped forming holes 12, and the three layers of the starfish-shaped forming holes 12 are arranged in a staggered and crossed manner circumferentially.
