Background technique
Cosmetic brushes are the main tools for makeup, and the quality of the bristles of the makeup brushes plays an important role in the makeup effect. Artificial hair is made of PBT particles through a wire drawing machine to replace part of natural animal hair to make makeup brushes. However, since the artificial hair for cosmetic brushes is made of PBT granules and drawn at high temperature by a wire drawing machine, the surface is smooth and the adsorption force for water and cosmetic powder is small, while the natural animal hair for cosmetic brushes has natural scales on the surface, so makeup The adsorption force of animal hair for brushes on water and cosmetic powder is much higher than that of artificial hair for cosmetic brushes. Because of this, artificial hair for makeup brushes cannot completely replace natural animal hair for makeup brushes.

The titanium crystal filament we developed through experiments is a filamentous structure with spherical protrusions on the surface. The filamentous structure is composed of PBT filamentous main body. The distribution state of the protrusions is determined by the raw material ratio of titanium dioxide, liquefied titanium powder and PBT in the preparation process. In the present invention, titanium dioxide and liquefied titanium powder are added to the main material PBT granules, so that the surface of the obtained artificial hair is uneven, and the water absorption, powder absorption and antibacterial properties of the artificial hair are increased. Compared with the existing artificial hair products for cosmetic brushes, the raw materials used in the present invention greatly improve the adsorption force of the cosmetic brush to water and cosmetic powder and have antibacterial function. It can greatly replace the amount of animal hair used in the production of cosmetic brushes, reduce and reduce the killing of animals, especially many wild animals, in line with the modern human’s green development concept of treating nature and animals.
