Example Embodiment
[0012] The present invention will be further described below in conjunction with the drawings and embodiments.
[0013] Such as figure 1 As shown, a circular spinneret for spinning fine denier includes a spinneret body 1, which is provided with a spinneret hole 2. One side of the spinneret hole 2 is a feed port, and the other side is For the discharge port, the spinneret body 1 is circular and has 144 holes.
[0014] The spinneret holes 2 of the present invention are arranged in a multi-layer concentric structure from the inside to the outside; in this way, the cooling effect of the nascent fiber can be significantly improved. The spinneret hole 2 has a circular shape and a diameter of 0.15 to 0.18 mm. The aspect ratio of the spinneret 2 is 3-4.
[0015] By adopting the circular spinneret for spinning fine denier filaments of the present invention, the flow rate of the melt in the micropores is effectively reduced, and high-quality porous fine denier filaments with dpf=0.5 can be ...
