Polyester spinneret plate

Abstract

The invention discloses a polyester spinneret, which belongs to the technical field of textile machinery, and includes a board body. The board body is provided with at least 4 groups of work areas, and the work areas are arranged radially from the center of the board body. Each group There are two rows of spinneret holes in the working area, the cross-section of the spinneret holes is in the shape of a semicircular fan, and the openings of the two rows of spinneret holes in each group of working areas are arranged face to face and cross each other. The structure of the invention is simple and the operation is convenient. The high-quality polyester yarn has uniform and stable cross-section, good quality, elongation at break exceeds 50%, shrinkage in boiling water is less than 4%, strong elasticity, and good spinning effect.

Description

technical field [0001] The invention belongs to the technical field of textile machinery, in particular to a polyester spinneret. Background technique [0002] Polyester is a commonly used fiber raw material. Polyester yarn with excellent performance has high elongation at break, low shrinkage in boiling water, strong elasticity, etc., and is widely used in the production of toys, clothing and other daily necessities. The medium polyester filament is basically processed by a spinneret, and the spinning melt is sprayed through the micro-holes on the spinneret to form primary fibers with a specific cross-section, and then solidified into filaments through the coagulation medium in the subsequent process. The shape directly determines the quality of the fiber precursor. The spinneret holes on the existing spinneret are mostly circular structures, and the spun fiber has poor strength, many materials and excellent performance. The performance of polyester yarn is as follows: Hig...

AI Technical Summary

Problems solved by technology

[0002] Polyester is a kind of fiber raw material commonly used, and the polyester yarn of excellent performance has higher breaking elongation, lower boiling water shrinkage, stronger elasticity etc., is suitable for making daily necessities such as toy, clothing in large quantities, and prior art The medium polyester filament is basically processed by a spinneret. The spinning melt is extruded through the micropores on the spinneret to form a primary fiber with a specific cross-section, and then solidified into a filament by the coagulation medium in the subsequent process. Its structure The shape directly determines the quality of the fiber precursor. Most of the spinneret holes on the existing spinneret have a circular structure, and the strength of the spun fiber is poor, and the material used is large. The performance of the polyester yarn with excellent performance is as follows: Higher elongation at break, lower shrinkage in boiling water, stronger elasticity, etc. In the prior art, polyester yarn is basically processed by spinnerets, which is difficult to meet actual production and market needs
