Problems solved by technology

[0003] Most of the existing spinnerets adopt a porous structure. When compounding, the skin layer has multiple holes distributed around the core layer holes. If there is pollution and plugging, the core layer is not in the center, or the pressure instability causes fluid turbulence, and the skin layer The core material is fused, causing the skin-core structure to be unstable

Embodiment Construction

[0020] In order to describe the technical content, structural features, achieved objects and effects of the present invention in detail, the following detailed description is given in conjunction with the embodiments and the accompanying drawings.

[0021] see Figure 1 to Figure 2 , a two-component spinneret, the spinneret 100 is installed in the spinneret assembly, the function of the spinneret assembly is mainly to divide the melt metered from the spinning pump into thin streams of specific shape and cross-section, and the spinneret assembly It also includes a filter plate and a distribution plate 200. A distribution plate 200 is arranged above the spinneret 100. The distribution plate 200 distributes the melt to the spinneret 100. A filter plate is arranged above the distribution plate 200 to prevent the melt from being blocked by impurities. Spinneret hole.

[0022] In this embodiment, the spinneret holes of the spinneret 100 are provided with guide holes 110 and micro h...

Abstract

The invention relates to the technical field of spinning, in particular to a two-component spinneret plate. The spinneret plate is mounted in a spinneret assembly; a spinneret orifice of the spinneret plate is provided with a guide hole and a micro hole; a buffer groove is formed between the guide hole and the micro hole; the guide hole is in the shape of an inverted triangular molten pool; a distribution plate is arranged above the spinneret plate; the distribution plate is provided with a core layer discharge hole and a skin layer discharge hole which correspondingly flow into the guide hole; the aperture of the skin layer discharge hole is smaller than that of the core layer discharge hole, and the horizontal position of the skin layer discharge hole is lower than that of the core layer discharge hole, so that the pressure of a core layer material in the guide hole is larger than that of a skin layer material; and the core layer and the skin layer in the guide hole are combined through pressure difference to form a stable skin-core structure, and the skin-core structure is sprayed out of the spinneret plate, so that the skin-core structure is more stable.

Description

technical field [0001] The invention relates to the technical field of spinning, in particular to a bicomponent spinneret. Background technique [0002] In the spinning process, the slices are extruded from the screw extruder and become a melt, and the melt is metered by a spinning pump to a spinneret for ejection to form a thin stream of melt, which is then stretched and laid into fibers by cooling. Among them, the spinneret has the greatest effect in the spinning process. The function of the spinneret is to convert the viscous polymer melt or solution into a thin stream with a specific cross-section through micropores, and pass through a solidifying medium such as air. Or coagulation bath solidification to form filaments, according to the type and specification of the fiber, there are different specifications, shapes, hole types, materials, etc., the spinneret can be divided into: ordinary type, which can be divided into melt spinning spinneret ( Its shapes are round, rec...
