Problems solved by technology

The function of the spinneret is to transform the viscous polymer melt or solution into a fine flow with a specific cross-section through the micropores, and to form filaments after being solidified by a coagulation medium such as air or a coagulation bath, so the spinneret The cross-sectional shape of the spinneret micropores is the key to determine the cross-sectional shape of the fiber. Although the ordinary cross-shaped, Y-shaped, T-shaped, triangular, H-shaped and other special-shaped fibers have significantly improved moisture conductivity compared with ordinary fibers, they are still not ideal

Embodiment Construction

[0014] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0015] like figure 1 , figure 2 Shown: the present invention comprises body 1, a plurality of spinneret microholes 2 that are arranged on the lower end surface of body 1, the cross-sectional shape of spinneret microhole 2 is cross-shaped, and the lengths of each side of cross-shaped 21, 22, 23, 24 are different Similarly, the intersection points of the spinneret microholes 2 are radially arranged with the body 1 as the center, and the intersection point of the adjacent spinneret microholes is 30 degrees from the center of the body; the cross-shaped transverse microholes 21, 22 and the longitudinal microholes 23 and 24 have a width of 100 microns to 200 microns, and the ratio of the length dimension to the width dimension of the spinneret microholes cross-shaped transverse microholes 21 and 22 is 6 to 12, and the spinneret microholes cross-shap...

Abstract

The invention discloses a cross special-shaped spinneret plate which is high in abnormity rate and good in spinning effect. The cross special-shaped spinneret plate comprises a body, a plurality of yarn spray micro holes formed in the lower end face of the body, the section of the yarn spray micro holes is in a cross shape, the lengths of the sides of the cross shape are different, the cross points of the yarn spray micro holes are arranged radially with the body as a center, and the transverse widths and the longitudinal widths of the cross yarn spray micro holes range from 100 microns to 200 microns. The cross special-shaped spinneret plate is suitable for cross special-shaped fiber production.

Description

technical field [0001] The invention relates to a chemical fiber melt spinning equipment, in particular to a spinneret suitable for the production of cross-shaped special-shaped fibers. Background technique [0002] Ordinary chemical fiber has poor wearing performance, and it is easy to produce stuffy and airtight feeling on the skin, so it cannot meet people's requirements for wearing comfort of chemical fiber textiles. By changing the cross-sectional structure of the fiber, fine grooves are formed on the surface of the fiber, and through the wicking effect, good moisture absorption and moisture conduction functions are produced, thereby improving the air permeability of the fabric and improving the comfort of the fabric. The function of the spinneret is to transform the viscous polymer melt or solution into a fine flow with a specific cross-section through the micropores, and to form filaments after being solidified by a coagulation medium such as air or a coagulation bath...
