Description
Technical Field

Background
The spinneret plate is a necessary part in the textile chemical fiber industry, and the outer diameter and the thickness of the spinneret plate are determined according to the size of a spinning assembly adopted by the spinneret plate. The spinneret plate surface area is divided into a feeding surface and a filament discharging surface, a certain number of spinneret orifices are arranged on the spinneret plate surface in a set arrangement mode, each spinneret orifice is formed by processing a cylindrical guide hole with a conical hole of 60-120 degrees and micropores communicated with the guide hole, and the shape of the section of each micropore determines the shape of the section of a fiber. The spinneret plate is used for extruding polymer melt or solution with high elastic viscous flow state into thin flow with a specific section through guide holes and micropores of the spinneret plate, and solidifying the thin flow by a solidification medium or a solidification bath positioned below the spinneret plate to form a strand with a corresponding section shape.
The micropores of current commercial spinnerets are generally circular, but more and more spinnerets with different cross-sections are used. The spinneret plate with the special cross-section of the polyester filament yarn in the prior art has a triangular shape, a trilobal shape, a cross shape, an H shape, a pentalobal shape, more lobal shapes and other structural lobal shapes, but the cross sections of the fibers have a common characteristic that no hollow exists, and the profiled fibers with capillary grooves only have the characteristics of moisture absorption and quick drying and cannot meet the requirements of light weight and air circulation, for example, CN102704007A is a spinneret plate with a cross-shaped elliptical spinneret orifice, can produce the polyester fibers with special cross-shaped cross-section shapes, and the fibers have capillary grooves but do not have hollow. The polyester filament hollow fiber spinneret plate in the prior art mostly adopts a circular section surrounded by 2C and 3C to form a simple circular hollow section, and does not have the characteristics of moisture absorption and quick drying. Some designs add one or more solid leaves to the 2C and 3C cross section, for example, CN 111235652A is a spinneret plate for producing the shaped hollow extinction fiber, which can produce the hollow fiber with solid leaves, and although the fiber has hollowness, the solid leaves only change the light refraction angle, and do not have the moisture absorption and quick drying characteristics of capillary grooves. There are also some designs in which a plurality of 2C, 3C circular cross sections are arranged in a line to make the fiber cross section in a flat hollow gourd shape, these hollowness degrees are very small, and there is no capillary groove with wicking effect, for example, CN106801265A 8-line hollow polyester fiber FDY filament and its preparation method, the fiber cross section is in a peanut shape with a certain hollowness degree, the formed groove is shallow, the included angle is large, and there is no wicking effect.
