In this study, the flat-section monofilaments of PBT for artificial eyelashes was developed, and the physical properties of the circular cross-section of artificial eyelashes were compared and observed, and the main performance of the artificial eyelash prototype was observed through processing for artificial eyelashes. In addition, a satisfaction survey of the prototype was conducted through a survey of consumers and artificial eyelash operators. It was found that the bending stiffness value of the monofilaments increased significantly as the thickness increased. As a result of measuring the bending properties of the flat-section PBT monofilaments, the bending stiffness was significantly lower than that of the circular-section PBT specimens of the same thickness. The deformed cross-section PBT monofilaments with flat cross sections developed in this study showed a light weight factor of less than 50% compared to the existing circular cross-section PBT ones. The adhesive strength of the developed PBT artificial specimens was greater than that of the existing circular cross-section yarn. It was also observed that the curl stability over time was excellent. As a result of the consumer survey, it was possible to obtain more than 85% of positive answers in the case of consumer subjects, and it was possible to investigate that the satisfaction of the operator subjects was more than 80% compared to the existing round-section eyelashes.

With the popularization of 5G networks and the development of AI (artificial intelligence) technology, Metaverse, which creates production capacity by combining virtual space and reality, is attracting attention. In this study, we searched for makeup applications with more than 100 million downloads from October 11, 2020 to November 3, 2020 through the Google Play Store. As a result of the search, four applications were found: YouCam Makeup, YouCam Perfect, Beauty Plus, and Sweet Snap. Based on the functions provided by the four applications, we attempted to suggest makeup functions applicable to Zepeto's avatar. Functions for the eyes (eyeliner, eyelashes, mascara, eye shadow, eye shape, eyebrow shape, lenses, double eyelids), functions for the nose (nose shape), functions for the mouth (lipstick, lip shape, smile function) ) Functions corresponding to the facial contour (contour, skin foundation, blusher, shading, highlighter, face painting, theme makeup) and functions corresponding to the body (body adjustment) were proposed. This study is the first in the beauty field to propose a method of applying the functions of the Metaverse platform as the importance of digital platforms is highlighted, and is the first to propose a makeup function applied to the Metaverse so that it can be used as important basic data in the future.
