인조 속눈썹False eyelashes

The artificial eyelash of the present invention includes an artificial hair part and an attachment part, and the artificial hair part and the attachment part are integrally formed by injection molding, and have excellent shape stability and elasticity.

The artificial hair part is formed on one surface of the attachment part, and is composed of 3 to 100 artificial hairs, the length of the artificial hair may be 0.1 to 50 mm, preferably 2 to 15 mm. The thickness of the artificial hair may be 0.05 to 2 mm, preferably 0.2 to 0.9 mm. The artificial hair part may be a combination of artificial hairs having one or more physical properties or shapes. As an example, the artificial hairs may be straight or curved, and a plurality of adjacent artificial hairs may cross each other or be arranged in a zigzag shape. The cross section of the artificial hair may be a polygon, such as a triangle, a square, a pentagon, a circle, or an oval, but is not necessarily limited thereto. When the cross section of the artificial hair is polygonal, the corners may be rounded, and the area of the cross section may be 0.002 to 5 mm 2 or preferably 0.03 to 0.8 mm 2.

Figure 2 shows a plan view of the artificial eyelashes according to an embodiment of the present invention, referring to Figure 2, the attachment portion 20 is configured to attach the artificial eyelashes to the skin of the person as shown in Figure 2 (a) It may be straight, or may be curved as shown in FIG. The length of the attachment portion may be 20 to 50 mm, preferably 30 to 40 mm. The thickness of the attachment portion may be 0.05 to 2 mm, preferably 0.2 to 0.9 mm.

The artificial hair part and the attachment part may be thermally processed, and may be manufactured by injection molding a thermoplastic elastomer (TPE) having a physical property such as rubber and having elastic properties such as rubber or a resin composition including the same.

The thermoplastic elastomer resin may be an olefin-based, styrene-based, amide-based, ester-based, urethane-based, silicone-based, PVC-based, or the like, and preferably, may be a styrene-based or olefin-based thermoplastic elastomer resin.

The styrene-based thermoplastic elastomer resin has a two-phase structure consisting of a soft segment imparting elasticity and a hard segment imparting rigidity as an elastic body closest to a rubber. For example, poly (styrene- b-butadiene-b-styrene (SBS), poly (styrene-b-isoprene-b-styrene) (SIS), poly (styrene-bethylene-b-butadiene-b-styrene) (SEBS), poly (styrene- b-ethyleneb-propylene-b-styrene) (SEPS).

As the olefinic thermoplastic elastomer resin, preferably, ethylene propylene diene monomer (EPDM) may be used, and the EPDM elastomer is composed of a soft phase and a hard phase of polypropylene, and the soft phase expresses rubber elasticity unique to the thermoplastic elastomer. In the molding process, the hard phase may exhibit a function of preventing plastic deformation by melting / plasticizing to express unique molding processability and then curing again.

As another embodiment of the present invention, when the injection molding is made of multiple, the attachment portion may be made of the same thermoplastic elastomer resin as one of the artificial hairs constituting the artificial hair portion. In other words, in the case of multiple injection molding, the first injection molding and the subsequent injection molding are performed, and when the thermoplastic elastomer resin used in the first injection molding and the subsequent injection molding is different, some of the artificial hairs constituting the final molded artificial hair part are It may be made of a thermoplastic elastomer resin different from the attachment portion.

In the multi-injection molding, the thermoplastic elastomer resin used in each injection molding step may be a thermoplastic elastomer resin having a different color by using a pigmented pigment, thereby manufacturing an artificial hair part composed of a plurality of artificial hairs having different colors. Therefore, it is possible to provide false eyelashes expressing multicolor. Further, by applying two or more kinds of thermoplastic elastomer resins having different physical properties, the physical properties between the attachment part and the artificial hairs constituting the artificial hair part or the artificial hair part can be partially adjusted. For example, by multi-injection into a thermoplastic elastomer resin having a different ductility, the attachment part uses a flexible soft elastomer, and the artificial hair uses a relatively rigid elastomer, thereby producing a product having a comfortable human body with a comfortable shape. .

According to another embodiment of the present invention, the uneven pattern 30 may be formed on one or more surfaces of one side and the other side of the attachment portion 20 as shown in FIG. Concave-convex pattern 30 can be attached to the skin around the eye when the artificial eyelashes, giving more flexibility to the attachment portion, and can increase the adhesion area can be easily attached to the skin surface and can be made naturally attached have. The concave-convex pattern may have a concave portion or a convex portion having a shape of a rectangle, a triangle, a circle, or the like as shown in FIG. 4 (d).
