Women are applying nail polish on the surface of their nails for nail beauty. However, the work is very cumbersome and it takes some time for the manicure to harden. In addition, the manicure applied directly to the nail can be tired and quickly get tired. For this reason, it is sometimes troublesome to remove the manicure with acetone or the like and reapply a manicure of a different color. Therefore, there is an economic burden because it is necessary to have a multi-color nail polish, and it is also harmful to nail health to repeat the process of frequently removing the nail polish with acetone and the like again. On the other hand, in nail beauty using nail polish, it is not easy to vary the shape of the nail itself.

In order to eliminate such inconvenience and inconvenience, artificial nails manufactured by injection molding have been developed. The artificial nail is designed to be adhered to the nail surface using an adhesive such as a double-sided tape. Since the surface of the artificial nail is in the same color as the resin, the surface of the artificial nail is coated with nail polish of a desired color in advance, and it is selected and used as necessary.

These artificial nails have a variety of patterns and colors that can be used by the user from time to time to change the convenience is convenient. However, when the user directly decorates the artificial nails in the resin color, it is not possible to satisfy the desire of women to decorate them more beautifully and elegantly, as the color or pattern is monotonously decorated as when applying nail polish.

Recently, in order to meet the needs of women, there is a high-quality by manually drawing complex patterns and shapes by using various colors of ink on the surface of the artificial nail manufactured by injection molding as described above. However, these advanced artificial nails have to be drawn manually on the surface of complex patterns and shapes, making the manufacturing difficult and the time required to manufacture them is very long. In addition, such a work requires a high level of skill and cannot be mass-produced, resulting in a high manufacturing cost and a large burden for a user.

Therefore, in order to solve the above problems, the present invention provides a method for easily manufacturing a large amount of artificial nails made of various colors or patterns in a short time and a large amount of artificial fibers produced by the manufacturing method. The purpose is to provide nails.
