Unless otherwise specified, "plurality" means two or more.

[0021] It should also be understood that the terms used in the utility model specification are only for the purpose of describing specific embodiments and are not intended to limit the utility model. As used in the utility model specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0022] It should be further understood that the term “and / or” used in the present specification and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0023] like Figure 1 and Figure 2 As shown, the embodiment of the present application provides a brush filament, and the surface of the brush filament 1 is distributed with a concave-convex structure 13. Specifically, the surface of the brush filament is distributed with uneven concave-convex structures, forming a layered scaly surface, which is conducive to the makeup powder to grasp the contacted powder, thereby improving the powder grasping power and makeup efficiency of the brush filament.

[0024] Powder grabbing performance test: Take ordinary PBT brush filaments as the standard base, use 3 makeup brushes with the same hair volume and hair type, dip them evenly into the same brand of powder once under the same force, and detect the powder area under a high-power microscope. Repeat the above operation 10 times and take the average value to obtain the data in the following table.

[0025] Brush head material Ordinary PBT wool Brush wire in this embodiment Powder grabbing performance 100％ 138％ 127％

[0026] In the specific implementation of this embodiment, the concavo-convex structure 13 includes a plurality of protrusions 131 and a plurality of concave portions 132, and the width of the protrusions 131 and the concave portions 132 is in the range of 0.3-0.8 microns. Specifically, since the powder particle size of cosmetics is generally about 0.3-0.8 microns, the powder concavo-convex structure with a width of 0.3-0.8 microns is distributed on the surface of the makeup brush wire of this embodiment, and its width is equivalent to the particle size of the powder, so it can easily grasp the powder it has touched, thereby improving the powder grasping force and makeup efficiency.

[0027] During the specific implementation of this embodiment, the raised portion 131 and the recessed portion 132 are irregularly shaped, which is conducive to the powder being hung on the surface of the brush filaments in a cross-displaced manner.

[0028] In the specific implementation of this embodiment, the brush filament 1 includes a peak section 11, and the peak section 11 is axially convex and concave. Specifically, the convex and concave peak section of the brush filament can achieve the extreme depth of the hair scale state, giving it a strong ability to grab and fix powder.

[0029] During the specific implementation of this embodiment, the brush filament 1 further includes a root segment 12 . The root segment 12 is cylindrical and can stably support the peak segment 11 .

[0030] During the specific implementation of this embodiment, the cross-section of the brush filament 1 is circular, which is beneficial to expanding the surface area of ​​the brush filament and the structural stability.

[0031] Based on the same inventive concept as the above-mentioned brush filaments, an embodiment of the present application further provides a cosmetic brush, the cosmetic brush comprises a brush head, and the brush head comprises a plurality of brush filaments 1 as described in any one of the above items.

[0032] Regarding the embodiments of the present utility model, it should also be noted that, in the absence of conflict, the embodiments of the present utility model and the features therein can be combined with each other to obtain new embodiments.
