Problems solved by technology

[0006] The purpose of the present invention is to solve the problem that the cooling effect of the existing spinneret is not good, the flow speed of the melt in the micropore is fast, so that the production efficiency of the coarse denier yarn is not high, and the fiber dyeing effect is poor, and a production method is proposed. High-quality special-shaped spinneret for spinning coarse-denier yarns that can enhance the cooling effect of primary fibers, improve the cooling uniformity of coarse-denier yarns, and improve the dyeing effect

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.

Abstract

A special-shaped spinneret plate for spinning heavy denier yarns comprises an elliptic body (1). 90-192 spinning holes (2) are arranged on the body (1). One side of each spinning hole (2) is a feed inlet. The other side of each spinning hole (2) is a discharge outlet. The plurality of spinning holes (2) are arranged in a three-layered concentric ellipse structure from inside to outside. The spinneret plate is capable of producing glazed heavy denier yarns of 300-500D. Due to heavier filament number, diameters of micropores are slightly larger than those of round holes of products of conventional specification, and flow speed of melts in the micropores can be lowered effectively. In addition, the ellipse spinneret plate is different from conventional round spinneret plates, distribution of the micropores is facilitated, enhancement of cooling effect of spun fibers is facilitated, cooling uniformity of the heavy denier yarn is improved, and dyeing effect of the heavy denier yarn is also improved.

Description

technical field [0001] The invention relates to a spinneret, in particular to a spinneret for producing imitation silk products, in particular to a special-shaped spinneret for spinning coarse denier silk. [0002] Background technique [0003] The spinneret is also called the spinning cap. The spinneret can transform the viscous polymer melt or solution through the spinneret hole into a thin stream with a specific cross-section, which is formed after being solidified by a coagulation medium such as air or a coagulation bath. silk strips. [0004] At present, the cooling effect of the spinneret for the production of coarse denier yarn is not good, and the flow rate of the melt in the micropores is fast, so that the production efficiency of coarse denier yarn is not high, the cooling effect of the primary fiber is poor, the inhomogeneity, and the dyeing effect are not good. Well, does not meet the needs of the existing technology. [0005] Contents of the invention [...
