Artificial hair spinning nozzle and artificial hair product manufactured using same

Abstract

An artificial hair spinning nozzle includes a nozzle body having a spinning hole extending into the nozzle body. In a cross-sectional view, the spinning hole includes a core section formed at the center of the nozzle body, and three branch sections each formed to radially protrude in an arc shape from the core section at a predetermined angle. The arc shape is bent along one direction to form an outer contour of the spun artificial hair. The branch section includes a convex circular part protruding in a convex circular shape on the end side of the branch section, and a concave circular part recessed between adjacent branch sections in a concave circular sectional shape circumscribed to circles of the convex circular part and the core section.

What is claimed is: 
     
         1 . An artificial hair spinning nozzle comprising:
 a nozzle body extending a predetermined length with a predetermined outer diameter and having a hollow spinning hole extending into the nozzle body in a longitudinal direction and into which a synthetic resin is injected to longitudinally spin artificial hair, wherein in a cross-sectional view, the spinning hole comprises:   a core section formed in a circular shape at the center of the nozzle body to serve as the center of the spun artificial hair, wherein the circular shape has a size smaller than the outer diameter of the nozzle body; and   a branch section composed of three branch sections formed to radially protrude in an arc shape from the core section at a predetermined angle, wherein the arc shape is bent along one direction to form an outer contour of the spun artificial hair, wherein the branch section includes:
 a convex circular part located outside the core section and protruding in a convex circular shape on the end side of the branch section so as to form the end side of a branch section of the spun artificial hair; and 
 a concave circular part recessed between adjacent branch sections in a concave circular sectional shape circumscribed to circles of the convex circular part and the core section, respectively, serving to form the inner side of the branch section of the spun artificial hair, 
   wherein a diameter of a convex circle forming the convex circular part is larger than a diameter of a concave circle forming the concave circular part, wherein the diameter of the concave circle forming the concave circular part is 25% to 85% of the diameter of the convex circle forming the convex circular part.   
     
     
         2 . The artificial hair spinning nozzle according to  claim 1 , wherein the diameter of a circle inscribed with the convex circle of the convex circular part is 1 mm to 2 mm. 
     
     
         3 . The artificial hair spinning nozzle according to  claim 1 , wherein a total area of the spinning hole is 55% to 75% of an area of a circle inscribed with the convex circular part of the branch section. 
     
     
         4 . An artificial hair product spun through the artificial hair spinning nozzle according to  claim 1 .
