Description

Technical Field

[0001] The utility model relates to the technical field of spinnerets, in particular to a spinneret for polyester staple fibers. Background Technique

[0002] A spinneret is a commonly used product in the textile chemical fiber industry. The spinneret includes a feed surface and a discharge surface. Feed holes are provided on the feed surface, and discharge holes are provided on the discharge surface. The function of the spinneret is to transform a viscous polymer melt or solution into a thin stream with a specific cross-sectional shape through micropores, and solidify it through a coagulation medium such as air or a coagulation bath to form filaments, that is, enter from the feed holes and exit from the discharge holes through the spinning channels.

[0003] For example, a spinneret for polyester staple fibers with the publication number CN221094379U includes a spinneret base plate, an annular plate, a fixed plate, a heat insulation tube, a wire guiding tube, a primary fixing plate, and a fixing column. One end of the spinneret base plate has a surface depression on the plate body, and a fixed plate is centrally fixed between the bottom of the surface depression and the spinneret base plate. An annular plate is clamped between the surface depression and the fixed plate. A bottom through hole penetrating the spinneret base plate downward is opened at the remaining bottom pit wall of the surface depression away from the fixed plate, and a heat insulation tube is fixed in the bottom through hole. A wire guiding hole is penetrated through the surface of the annular plate above the heat insulation tube. By setting an assembled spinneret, a ring plate structure that can pass through the melt of polyester staple fiber raw materials is clamped at the spinneret. After the wire passing structure at the annular plate is worn and deformed, the ring plate structure of the spinneret of the utility model can be directly disassembled and replaced, effectively avoiding the problem of increased spinning cost of polyester staple fibers caused by the overall replacement of the existing spinneret.

[0004] The heat dissipation performance of the above technical solution is limited in actual application, and it is difficult to ensure that the fibers are quickly cooled during the process of passing through the spinneret, and the filament forming effect is limited.
