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.
