Description
CROSS-REFERENCE TO RELATED APPLICATIONS

This is a U.S. patent application which claims the priority and benefit of Chinese patent application number 202111067893.8, filed on Sep. 13, 2021, the disclosure of which is incorporated herein by reference in its entirety.


TECHNICAL FIELD

This disclosure relates to the field of cosmetics manufacturing, and more particularly relates to magnetic false eyelashes and a preparation method thereof.


BACKGROUND

Magnetic false eyelashes have been popular in the market for several years as a fashionable fast-moving consumer product. Although they have been sought after by many beauty lovers, their shortcomings are also obvious, as follows.


1. In existing magnetic false eyelashes, 3-10 magnets are typically inlaid at the position of the eyelash stem with chemical quick-drying glue, where the sizes of the magnets have an even distribution depending on the length of the eyelash stem. Most of the magnets are 3 mm long×1 mm wide×0.3 mm high. They are relatively very large and prominent, where each magnet has edges and corners, and has a very obvious bumpy touch when inlaid in the eyelash stem. The corners and edges can easily scratch the eye skin. It is very uncomfortable to wear, and the magnet is very easy to fall off. It has a very small number of available use times, which also increases the cost of use.


2. The eyelashes are mostly made of PVC material, which is not environmentally friendly. A few eyelash filaments are made of PBT and PET materials, but they have defects such as long natural degradation time.
