Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The above and other objectives, features, and advantages of the present disclosure will be more clearly understood from the following detailed description when taken in conjunction with the accompanying drawing, in which:

[0019] FIG. 1 is a cross-sectional view illustrating an artificial hair spinning nozzle according to an exemplary embodiment of the present disclosure.

DETAILED DESCRIPTION OF THE INVENTION

[0020] Hereinafter, an artificial hair spinning nozzle according to the present disclosure will be described with reference to the accompanying drawing.

[0021] FIG. 1 is a cross-sectional view illustrating an artificial hair spinning nozzle according to an exemplary embodiment of the present disclosure.

[0022] The artificial hair spinning nozzle according to the present disclosure includes a nozzle body 100 that extends a predetermined length with a predetermined outer diameter and has a hollow spinning hole 200 that extends into the nozzle body 100 in a longitudinal direction and into which a synthetic resin is injected to longitudinally spin artificial hair. The synthetic resin injected into the spinning hole 200 uses a known polyester having excellent curl generation and retention, which is necessarily required as an artificial hair fiber.

[0023] The artificial hair spinning nozzle according to the present disclosure may be separately manufactured so that the spinning nozzle may be inserted and fixed to a spinning plate, or otherwise the nozzle body 100 may be integrally formed with the spinning plate. A plurality of artificial hair spinning nozzles according to the present disclosure is installed side by side so that artificial hairs can be spun therethrough.

[0024] As illustrated in FIG. 1, the cross-sectional shape of the artificial hair spinning nozzle includes a core section 210 and branch sections 220 each having a convex circular part 230 and a concave circular part 240.

[0025] The core section 210 is a section that is formed at the center of the nozzle body 100 to serve as the center of the spun artificial hair, with a circular shape having a size smaller than the outer diameter of the nozzle body 100.

[0026] The branch section 220 consists of three branch sections that are formed to outwardly protrude in an arc shape from the core section 210 at a certain angle, that is, 120 degrees, so that the arc shape is bent along one direction to form the outer contour of the spun artificial hair. Here, the diameter of the arc is larger than the diameter of the convex circular part 230 and smaller than the diameter of the nozzle body 100.

[0027] The outer surface of the artificial hair spun through the branch section 220 has natural gloss obtained by spread reflection of light. In addition, the shape of the branch section serves to give volume to hair.

[0028] The outer surface of the artificial hair spun through the convex circular part of the branch section 220 can realize a deep color together with the inner surface of the artificial hair spun through the concave circular part 240 of the branch section to be described later. That is, the outer surface of the artificial hair spun through the convex circular part of the branch section 220 and the inner surface of the artificial hair spun through the concave circular part 240 of the branch section bring different gloss due to the spread reflection, so that a deep color can be realized.

[0029] The convex circular part 230 is located outside the core section 210 and protrudes in a convex circular shape on the end portion of the branch section 220 so as to form the end side of a branch section of the spun artificial hair.

[0030] Since the end side of a branch section 220 of the artificial hair is spun in a circular form through the convex circular part 230, the artificial hair has soft tactility like a real hair, as well as more hair volume.

[0031] The concave circular part 240 is recessed between the inner side and outer side of the branch section 220 in a concave circular sectional shape that is circumscribed to the circles of the convex circular part 230 and the core section 210, respectively, serving to form the inner side of the branch section of the spun artificial hair.

[0032] As described above, according to the present disclosure, since the three branch sections 220 each have a direction in which the branch section 220 is bent (rotated) along one direction, it is possible to maintain curl generation and retention, to provide more hair volume, and to realize a natural gloss unlike the conventional artificial hair that reduces gloss by using an extinction agent since the three types of different gloss due to spread reflection of light are blended for three branch sections 220. In addition, the artificial hair formed with the three branches can facilitate combing, unlike the simple conventional artificial hair having the crowbar or Y-shape. Further, since the artificial hair forms the branch section 220 of three branches and has a directional feature of bending (rotating) along one direction, there is an effect of improving the straightness of the artificial hair compared to the conventional artificial hair. Furthermore, the three-pronged branch section 220 not only allows the hair thickness to be maintained similar to that of human hair, but also allows the hair weight to be reduced, and the amount of synthetic resin consumed for spinning the artificial hair can be reduced, resulting in cost reduction.

[0033] According to the present disclosure, the diameter D1 of a convex circle forming the convex circular part 230 is larger than the diameter D2 of a concave circle forming the concave circular part 240, wherein the diameter D2 of the concave circle forming the concave circular part 240 is preferably 25% to 85% of the diameter D1 of the convex circle forming the convex circular part 230.

[0034] When the diameter D2 of the concave circle forming the concave circular part 240 is less than 25% of the diameter D1 of the convex circle forming the convex circular part 230, there is a problem in that the core section 210 becomes much larger, the branch sections 220 become less elastic, and the hair weight increases.

[0035] When the diameter D2 of the concave circle forming the concave circular part 240 is more than 85% of the diameter D1 of the convex circle forming the convex circular part 230, there is a problem in that the elasticity of the branch sections 220 is large, a curl generation and retention feature becomes much deteriorated, and although the hair weight decreases due to a reduction in the size of core section 210, such a reduction causes detachment of the branch sections, resulting in a damage to the hair.

[0036] It is preferable that the diameter of a circle inscribed with the convex circle of the convex circular part 230 be 1 mm to 2 mm.

[0037] If the diameter of the circle inscribed with the convex circle of the convex circular part 230 is less than 1 mm, it is difficult to manufacture the artificial hair spinning nozzle. In addition, if the diameter of the circle inscribed with the convex circle of the convex circular part 230 is more than 2 mm, the elasticity of the branch section of the spun artificial hair decreases and the hair becomes stiff, thereby greatly degrading the softness of the hair.

[0038] It is preferable that the total area of the spinning hole 200 be 55% to 75% of the area of the circle inscribed with the convex circular part 230 of the branch section 220.

[0039] When the total area of the spinning hole 200 is less than 55% of the area of the circle inscribed with the convex circular part 230 of the branch section 220, the elasticity of the branch sections 220 is large, a curl generation and retention feature becomes much deteriorated, and although the hair weight decreases due to a reduction in the size of core section 210, such a reduction causes detachment of the branch sections 220, resulting in a damage to the hair.

[0040] When the total area of the spinning hole 200 is more than 75% of the area of the circle inscribed with the convex circular part 230 of the branch section 220, the core section 210 becomes much larger, the branch sections 220 become less elastic, and the hair weight increases.

[0041] The artificial hair spun by the artificial hair spinning nozzle according to the present disclosure is used for hair ornaments such as wigs, hairpieces, and braids.

[0042] Although the present disclosure has been described and illustrated with respect to the specific embodiments, those skilled in the art will appreciate that various improvements and modifications are possible, without departing from the scope and spirit of the present disclosure as disclosed in the accompanying claims.
