Spinneret plate with circular and trifoliate tiny pores

Abstract

The invention discloses a spinneret plate with circular and trifoliate tiny pores. The spinneret plate with the circular and trifoliate tiny pores comprises a spinneret plate face (1), wherein the spinneret tiny pores are formed in the spinneret plate face (1), a feed port is formed in one face of each spinneret tiny pore, and a discharge port is formed in the other face of each spinneret tiny pore. The spinneret plate with the circular and trifoliate tiny pores is characterized in that the spinneret plate face (1) is circular, the spinneret tiny pores are respectively in a circular shape and a trifoliate shape, and the number of the spinneret tiny pores is 24-96. Accordingly, breaking strength of polyester filament yarns produced through the spinneret plate with the circular and trifoliate tiny pores is observably improved. Hand feelings and gloss of fabrics woven through the polyester filament yarns are different from fabrics woven through round hole polyester filament yarns and polyester filament yarns with singe trifoliate sections. The polyester filament yarns obtained through the spinneret plate with the circular and trifoliate tiny pores are high in quality, have good flash effects, and are fine and smooth in hand feeling, and good in moisture absorption and air permeability, and simultaneously the fabrics woven through the polyester filament yarns produced through the spinneret plate with the circular and trifoliate tiny pores are soft in hand feeling and can be used as high quality clothing material.

Description

technical field [0001] The invention relates to a spinneret, in particular to a spinneret with mixed micropore shapes, in particular to a spinneret with both circular and trilobal micropores. Background technique [0002] The spinneret, also known as the spinning cap, can transform the viscous polymer melt or solution into a thin stream with a specific cross-section through the spinneret hole, and form filaments after being solidified by a coagulation medium such as air or a coagulation bath. [0003] At present, the fiber with a single round hole has a circular cross-section, so there are few refraction surfaces for external light, and the gloss effect of the cloth surface is average. Due to the special shape of the fiber cross-section, the single trilobal fiber increases the refraction surface to the external light. If it is spun with light, it will have a luster similar to that of a diamond. The position of the long midpoint is prone to sag, which affects the refraction ...

Problems solved by technology

[0003] At present, the fiber with a single round hole has a circular cross-section, so there are few refraction surfaces for external light, and the gloss effect of the cloth surface is average.

Due to the special shape of the fiber cross-section, the single trilobal fiber increases the refraction surface to the external light. If it is spun with light, it will have a luster similar to that of a diamond. The position of the long midpoint is prone to depression, which will affect the refraction of external light and cannot obtain satisfactory results.

[0004] The polyester filament produced by a single micropore is difficult to show a delicate hand feeling and bright color when weaving into a fabric, and the obtained fabric has poor hygroscopicity and air permeability, which cannot meet the needs of the existing technology
