Embodiment Construction

[0012] The present invention will be further described below in conjunction with the drawings and embodiments.

[0013] Such as figure 1 As shown, a circular spinneret for spinning fine denier includes a spinneret body 1, which is provided with a spinneret hole 2. One side of the spinneret hole 2 is a feed port, and the other side is For the discharge port, the spinneret body 1 is circular and has 144 holes.

[0014] The spinneret holes 2 of the present invention are arranged in a multi-layer concentric structure from the inside to the outside; in this way, the cooling effect of the nascent fiber can be significantly improved. The spinneret hole 2 has a circular shape and a diameter of 0.15 to 0.18 mm. The aspect ratio of the spinneret 2 is 3-4.

[0015] By adopting the circular spinneret for spinning fine denier filaments of the present invention, the flow rate of the melt in the micropores is effectively reduced, and high-quality porous fine denier filaments with dpf=0.5 can be ...

Abstract

The invention provides a round spinneret plate for spinning fine denier filaments. The spinneret plate for spinning the fine denier filaments comprises a spinneret plate body (1), wherein one hundred and forty four spinneret holes (2) are formed in the spinneret plate body (1); one face of each spinneret hole (2) is a material inlet; the other face of each spinneret hole (2) is a material outlet; the spinneret plate body (1) is round; and the spinneret plate can be used for producing the multihole fine denier filaments with the denier per filament (dpf) being equal to about 0.5. The distribution of the spinneret holes of the round spinneret plate is beneficial to the enhancement of the cooling effect of nascent fiber, the improvement of the cooling evenness of the fine denier filaments and the improvement of the dying effect; and therefore, the spinneret plate for spinning the fine denier filaments has wide application prospect.

Description

Technical field [0001] The invention belongs to the textile field and relates to a spinneret, in particular to a circular spinneret for spinning fine denier. Background technique [0002] The spinneret is also called the spinning cap. The spinneret can transform the viscous polymer melt or solution through the spinneret into a trickle with a specific cross-section, which is formed after solidification by a solidification medium such as air or a solidification bath. Silk strips. [0003] At present, the existing spinnerets have relatively primitive production processes for fine denier filaments with a monofilament size dpf=0.5, with poor production quality, poor cooling effect, slow cooling speed, and poor dyeing effect, which cannot meet the requirements of the prior art. Demand. Summary of the invention [0004] The purpose of the present invention is to solve the problems of poor cooling effect of the existing spinneret for spinning fine denier, low production efficiency of fine...
