Description

TECHNICAL FIELD [0001] The present invention relates to an artificial nail and a method for manufacturing the same,

The present invention relates to an artificial nail technology, and more particularly, to an artificial nail and a method of manufacturing the artificial nail which are designed so that the release film can be easily removed without being damaged when actually attached to the nail, .

Currently, artificial nails are being released in a wide variety of shapes and patterns, and various methods of attaching them to natural nails are also disclosed. A method of using an instant adhesive, a double-sided tape and a free glue to fix an artificial nail to a natural nail has been used.

According to the method using the instant adhesive, a predetermined amount of instant adhesive is applied to the back surface of the artificial nails or the top surface of the natural nails, and then the artificial nails are pressed onto the natural nails. Instant adhesives have the advantage of being easy to use. Natural nails may be damaged by their toxic components, and they are limitedly used due to disadvantages of detachment and inconvenience. Preglue is used in a similar way to instant glue, has a neutral pH, has no non-toxic ingredients, and has a clear set clear. However, the preglu is relatively expensive as compared with the instant adhesive, and thus it is also being used in a limited manner. Compared to instant adhesives and preglues, double-sided tape has less damage to natural nails, is easy to use, and has a relatively low cost, so that the development and use of the technology is steadily increasing.

In the artificial nails using the conventional double-sided tape, there is a problem that when the release film for protecting the double-sided tape is not easily separated from the adhesive when it is detached, or when it is stored in the artificial nail case due to the protruded release film, Accordingly, there is a need for an artificial fingernail that can easily remove the release film without being damaged when actually attached to the fingernail, and can be effectively stacked on the storage case.

In this case, an incision is formed in the first sheet so that the first sheet is not separated from the adhesive sheet even if the adhesive sheet adheres to the back surface of the artificial nail body and is deformed. Thereafter, the first sheet is separated from the adhesive sheet to expose the other surface of the adhesive sheet, and then the other surface of the adhesive sheet is pressed against the upper surface of the natural nail to attach the artificial nail to the natural nail. In the case of mass production of artificial nails using a jig and a press, a curved line is formed on both sides of the adhesive portion having an area corresponding to each of the artificial nail bodies in the artificial nail adhesive tape, Can be prevented from being incorrectly attached to the back surface of the semiconductor wafer W.

ABS resin is a thermoplastic resin that improves mechanical strength, heat resistance and weather resistance while maintaining the excellent permeability, workability and electrical properties of polystyrene (PS). ABS resin has the advantage that it can be colored in any color and can produce a glossy molded article. The ABS resin can be modified to control the composition of the resin and the mixing ratio thereof with other resins, so that the ABS resin can be manufactured to have suitable characteristics depending on the application. [0002] Polypropylene (PP) is widely used because it can be made lightweight, has excellent molding processability, chemical resistance, mechanical properties such as tensile strength and bending strength, excellent thermal properties, and economical advantages . The artificial nail body 110 can be improved in luster and workability by blending polypropylene (PP) with ABS resin. In addition, the artificial nails 100 made of ABS and polypropylene (PP) can be eco-friendly artificial fingernails, both of which are environmentally friendly plastic that does not contain environment hormones and which is harmless to the environment, both of ABS resin and polypropylene (PP).
