Embodiment Construction
[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0021] Such as figure 1 As shown, a special-shaped spinneret for spinning coarse denier yarns includes a spinneret body 1, and a spinneret hole 2 is arranged on the spinneret body 1. One side of the spinneret hole 2 is a feed inlet, and the other side is an outlet. The feed opening, the spinneret body 1 is oval.
[0022] There are 90-192 spinneret holes 2 of the present invention, and a plurality of spinneret holes 2 are arranged in a three-layer concentric elliptical structure from the inside to the outside; the micropores are arranged in three circles, but the micropores in each circle will be arranged in a random order, so that , The cooling effect of the primary fiber is good. Such as figure 1 As shown, there are 28 spinneret holes 2 in the first circle from the innermost layer, 48 in the second circle, and 68 in the third circle.
