Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a manufacturing method of elastic artificial eyelashes,

The present invention relates to a method of manufacturing elastic eyelashes having elasticity, and more particularly, to a method of manufacturing artificial eyelashes having elasticity by fixing artificial eyelashes using a stretchable polymer and cutting artificial eyelashes fixed with polymers. The present invention relates to a method for manufacturing artificial eyelashes having elasticity.

As recent technology develops, artificial eyelashes are popular among women and are becoming popular. Many eyelashes are worn by many women because eyelashes are long and eyes are enlarged when artificial eyelashes are attached. Since the film used in conventional artificial eyelashes has no elasticity, there has been a problem that women who wear artificial eyelashes complain of fatigue of the eyelid or adversely affect the eyes. However, there are no concrete methods to manufacture elastic eyelashes.

Regarding prior art related to artificial eyelashes having elasticity, Registration Utility Model No. 20-0315906 relates to artificial eyelashes having elasticity, comprising a plurality of hair follicles having a predetermined length, and a plurality of hair follicles In the conventional eyelashes, an auxiliary support formed of a resilient material is coupled to the forehead, and the forehead inserted into the support is cut at regular intervals along the longitudinal direction using a cutting blade. A technique relating to artificial eyelashes having elasticity capable of being deformed in a fluid manner according to muscle movement is proposed. The above technique has a problem in that it is not easy to manufacture since the cutter blade is used to cut at predetermined intervals after the formed auxiliary members are coupled.

Japanese Patent Laid-Open Publication No. 10-2013-0005907 discloses a method for manufacturing artificial eyelashes, comprising the steps of: a) melt extruding a synthetic resin composition, spinning it, and stretching to produce a monofilament; b) processing the monofilament into a bundle; c) cutting the bundle; d) sealing one end of the bundle with a carrageenan, agar, or a water-soluble resin, or heating the monofilament to a synthetic resin melting temperature to form a block; e) fixing the opposite end of the block to the screen with a screen, dipping the tenter in a processing bath containing an alkali solution, and tapering the processed block; and f) dipping the block in a processing tank containing an alkali solution to tear the treated block. The above-described technique has the same problem as the conventional artificial lashes because the base material has no elasticity.

U.S. Patent Application Publication No. US2014 / 0332025 relates to artificial eyelashes and a method of manufacturing the same, and proposes a method of forming and molding artificial eyelashes entirely using a molding frame. Since the eyebrows and the base material are both made of elastic materials, there is a problem in that the eyebrows can not be finely processed.

Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a method of manufacturing artificial eyelashes having elasticity by using a base material as an elastic material.

It is another object of the present invention to provide a method for manufacturing artificial eyelashes having elasticity capable of bonding artificial eyelashes and base materials without using an adhesive.

According to an aspect of the present invention, there is provided a method of manufacturing a semiconductor device, comprising: preparing a lower film having a bonding surface on one surface thereof and an upper film having an adhesive surface on one surface thereof; Attaching artificial eyebrows to the lower film; Attaching an upper film so as to overlap the lower film with the artificial eyebrow attached thereto; Positioning the upper frame and the lower frame such that the upper frame and the lower frame are vertically aligned with each other at a predetermined distance apart from the lower film and the upper film to which the artificial eyebrows are attached; Applying a polymer liquid to the grooves formed by the lower film, the upper film, and the upper and lower molds; Uniformly distributing the applied polymer solution to the height of the film; Drying said uniformly distributed polymer liquid; And cutting the dried polymer to a predetermined width and a predetermined angle. The present invention also provides a method for manufacturing a stretchable artificial eyelash.

In the present invention, the upper frame or the lower frame has a shape of '?', A silicon pad is formed on one side thereof, and a surface on which the silicon pad is formed is in contact with the artificial eyebrows.

In the present invention, the polymer liquid may be any one of a vinyl resin, a polyethylene resin, a polypropylene resin, a polyester resin, a polyurethane resin, a fluorine resin, a polyol resin, an epoxy resin, a vinyl acetate resin, a silicone resin, a styrene resin, An aminoalkyd resin, a urea resin, a toluene resin, a grit resin, EVA or latex dissolved in a solvent.

In the present invention, the predetermined angle to be cut is 15 to 90 degrees.

In the step of applying the polymer liquid in the present invention, a polymer film having no adhesive surface is placed under the artificial eyelashes in the frame formed by the lower film, the upper film, the lower frame and the upper frame, and the polymer film and the artificial eyelashes And the polymer liquid is applied onto the substrate.

The thickness of the polymer formed by drying the polymer solution applied in the present invention is 0.1 to 1.5 mm.

The present invention has the advantage that fatigue can be reduced because the base material is stretchable, so that when the wearer blinks, it flexibly responds to the curvature of the eyelid.

In addition, the present invention has the advantage of being capable of mass production of artificial eyelashes made of stretchable polymer, thereby reducing manufacturing costs.

Further, since the present invention does not use an adhesive, it has an advantage that it does not adversely affect the eye fatigue or eyes caused by the adhesive.

FIG.

1 to 7, a method for manufacturing artificial eyelashes having elasticity according to the present invention will be described in detail. Fig. 1 shows a step of bonding the upper film 10b and the lower film 10a to each other first. As shown in the figure, the artificial eyebrows 1 are first attached to the lower film 10a. The lower film 10a is composed of a film body 11a and an adhesive surface 12a formed on one side of the film body 11a. As shown in the figure, the artificial eyebrows 1 are adhered to the adhesive surface 12a. A plurality of artificial eyebrows 1 are attached to the lower film 10a so that a plurality of artificial eyelashes can be manufactured by one-time processing. When the attachment of the artificial eyebrows to the lower film 10a is completed, the upper film 10b is attached to the upper side thereof. The upper film 10b is composed of the film body 11b and the adhesive surface 12b as in the case of the lower film 10a and the adhesive surface 12b adheres the upper portion of the artificial eyebrow 1. [

2 shows a state in which the artificial eyebrows 1 are fixed with the upper film 10b and the lower film 10a and then an upper frame 20b and a lower frame 20a are provided in front of the upper film 10b and the lower film 10a Respectively. As shown in the figure, the upper frame 20b or the lower frame 20a is formed in the form of "┌┐". The upper frame 20b is composed of an upper frame body 21b in the shape of a '?' And a silicon pad 22b bonded to one side of the upper frame body 21b. The lower frame 20a is composed of a lower frame body 21a having a shape of '?' And a silicon pad 22a formed on one side thereof. As shown in the drawing, the lower frame 20a is positioned so as to be in contact with the front of the lower film 10a. The lower frame 20a is positioned below the artificial eyebrow 1. Next, the upper frame 20b is placed on the upper portion of the lower frame 20a and brought into contact with the upper film 10b. The upper film 10b, the lower film 10a, and the upper frame 20b and the lower frame 20a form a rectangular shape.

FIG. 3 shows that the grooves 30 are formed by the upper film 10b, the lower film 10a, the upper frame 20b and the lower frame 20a according to the process of FIG. Since the manufacture of artificial eyelashes is performed on a flat plate, holes are formed by the upper film 10b, the lower film 10a, the upper frame 20b and the lower frame 20a, I will describe it. The groove 30 is formed in a rectangular shape and the height of the upper film 10b and the lower film 10a and the upper and lower frames 20b and 20a are determined according to the thickness of the artificial eyelashes. That is, for example, when the thickness of the artificial eyelashes is 1 mm, the thickness of the upper film 10b, the lower film 10a, the upper frame 20b and the lower frame 20a is 1 mm. If the polymer can be shrunk by drying, the coating thickness of the polymer liquid may be determined taking into account the amount of shrinkage.

4 shows a state in which the polymer liquid is applied to the grooves 30. As shown in Fig. The groove 30 is coated with the polymer liquid 40 dissolved in the solvent, and the coating method, the spraying method or the direct coating method can be used. The applied polymer liquid 40 is subjected to a selecting operation so that the upper portion of the groove 30 can be flattened so as to be flat. That is, the polymer liquid is evenly pushed from one end to the other end by using a separate flat plate so as to have a constant height. Then, after selecting smoothly, it is dried for a certain time. Conveyor tunnels (not shown) can be used for drying by wind, and in conveyor tunnels, hot wind drying and cold wind drying can be carried out.

5 shows a state in which the upper mold 20b and the lower mold 20a are removed after the polymer solution is dried to remove the solvent. As shown in the drawing, when the upper frame 20b and the lower frame 20a are removed, only the dried polymer 40, the upper film 10b and the lower film 10a are left.

Fig. 6 shows that the sloped surface 41 is formed by cutting the dried polymer at a constant width and a constant angle. The cutting angle can be cut to various angles from 15 to 90 °. By cutting at a constant width and constant angle, the mass moment of inertia of the polymer can be increased to increase the stiffness according to the shape.

Fig. 7 shows that the artificial eyelashes are separately cut one by one. As shown in the drawing, the cut artificial eyelashes are subjected to a curvature forming step to form curved lines according to the shape of the eyes. When the artificial eyelashes are formed with a certain curvature, the manufacturing process of the artificial eyelashes is finished, and thereafter, a plurality of pieces are packed into one pack and the like, and the work is finished.

FIG. 8 shows another embodiment, which is the same as the method of FIGS. 1 to 7, except that the polymer film 50 is further added to the lower portion of the groove 30. FIG. And thus the polymer liquid is applied to the top of the polymer film 50. [ Since the remaining methods are the same, a concrete method will be omitted. Since the polymer film 50 is located below the polymer liquid 40, the stiffness of the artificial eyelashes by the polymer film 50 is increased. The polymer film 50 is not necessarily coincident with the size of the groove 30 but when it is matched the polymer film 50 is inserted into the groove 30 and the polymer solution 50, There is an advantage that the work to be applied on the top becomes easier.

Fig. 9 is a cross-sectional view of the dried polymer 40 produced by the method of Fig. 8, the polymer film 50 attached to the lower part of the dried polymer 40, and the polymer film 50 attached to the lower film 10a . The artificial eyelashes are made more rigid by the polymer film 50, so that the artificial eyelashes can be easily shaped to have a constant curvature.

Fig. 10 shows that the polymer 40 is cut at a predetermined angle to form the inclined surfaces 41 and 51, and the subsequent steps are the same as those in Fig.

The polymer liquid used in the present invention may be any one of a vinyl resin, a polyethylene resin, a polypropylene resin, a polyester resin, a polyurethane resin, a fluororesin, a polyol resin, an epoxy resin, a vinyl acetate resin, a silicone resin, a styrene resin, , An aminoalkyd resin, a urea resin, a toluene resin, a grit resin, EVA, or a latex is dissolved in a solvent. Therefore, even if the polymer is not included in the resin, it is also within the scope of the present invention that the polymer resin is soluble in a solvent and then dried and then stretched. Also, the polymer film 50 may be formed of a stretchable material. In addition, the polymer thickness may be up to 1.5 mm, and the minimum thickness of the polymer to maintain a constant curvature shape due to the polymer's own stiffness may be 0.1 mm, so that the polymer thickness is 0.1-1.5 mm .

As described above, the present invention is not limited to the above-described embodiments, and various changes and modifications may be made without departing from the scope of the present invention as defined in the appended claims. And such modifications are within the scope of the present invention.
