Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the cooling effect of the existing spinneret is not good, the fluidity of the melt in the micropore is poor, so that the production efficiency of the ultrafine denier is not high, and to propose a high-quality, high-quality spinneret. High degree of hole irregularity, the fiber products produced have good hygroscopicity and air permeability, fine denier three-lobed special-shaped micro-porous spinneret

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] Such as figure 1 As shown, a fine-denier three-lobe special-shaped microporous spinneret includes a spinneret body 1, and a spinneret hole 2 is arranged on the spinneret body 1. One side of the spinneret hole 2 is a feed inlet, and the other side is a Discharge port, the discharge port of spinning hole 2 is a trilobal micropore, and the interval between adjacent leaves is 120 °. The top of each leaf of the trilobal micropore is a semicircle, and the diameter is the width of the leaf. 0.60-0.85 mm; the two adjacent leaves are arc-shaped, and the radius of the arc is 0.15-0.18 mm; the leaf length of the trefoil microhole, that is, the distance from the center point of the trefoil to the top of the leaf is 0.2-0.23mm .

[0020] The number of spinneret holes of the present invention is 20-36, and a plurality of spinneret holes 2 are arranged in a t...

Abstract

The invention provides a fine denier three-leaf shaped micro-porous spinneret plate, comprising a spinneret plate body (1). A spinneret hole (2) is formed in the spinneret plate body (1); a feeding opening is formed in one surface of the spinneret hole (2), and a discharging opening is formed in the other surface of the spinneret hole (2); the discharging opening of the spinneret hole (2) is a three-leaf micro-pore; an interval angle between each two adjacent leaves is 120 degrees; the top end of each leaf of the three-leaf micro-pore is semicircular; and the adjacent part between the two leaves is arc. With the adoption of the fine denier three-leaf shaped micro-porous spinneret plate provided by the invention, the flow effect of flux inside the micro-pore can be improved, and the spinning property of a fiber is enhanced. The end surface of a finished yarn is in an imitated-triangle shape, and has silk-like brightness. Meanwhile, the total fineness of the fiber is relatively thin, and the fineness of the single yarn is lower than 1.5 dtex, so that the fiber has good moisture preservation property and air permeability.

Description

technical field [0001] The invention relates to a spinneret, in particular to a spinneret for producing spun silk products, in particular to a fine-denier trilobe special-shaped micro-hole spinneret. [0002] Background technique [0003] The spinneret is also called the spinning cap. The spinneret can transform the viscous polymer melt or solution through the spinneret hole into a thin stream with a specific cross-section, which is formed after being solidified by a coagulation medium such as air or a coagulation bath. silk strips. According to different fiber specifications, it can be divided into ordinary silk fiber, fine silk fiber and ultra-fine silk fiber. Ultra-fine silk fiber is also called ultra-fine denier. Because it is thinner than traditional fibers, it has a fluffier and softer touch than ordinary fibers, and can overcome the shortcomings of natural fibers that are easy to wrinkle and artificial fibers that are not breathable. However, at present, the coolin...
