Abstract
The application relates to the technical field of cosmetic tools, and particularly discloses an animal wool-like polyester silk cosmetic brush hair and a production process thereof. The imitation animal hair polyester silk cosmetic brush hair is prepared from the following raw materials in parts by weight: 60-70 parts of polyester resin, 3-6 parts of nano pearl powder, 2-6 parts of titanium dioxide, 19-25 parts of an antibacterial agent and 1-2 parts of a lubricant, wherein the antibacterial agent is prepared from the following raw materials in parts by weight: 5-10 parts of polyester resin, 5-8 parts of graphene oxide/silver compound, 2-3 parts of organic bentonite, 1-3 parts of chitosan oligosaccharide and 2-4 parts of nano bamboo charcoal powder; the preparation method comprises the steps of mixing, melt spinning, shredding, maofeng and after-finishing. The antibacterial agent is added into the raw materials of the cosmetic brush hair, so that the antibacterial performance of the cosmetic brush hair is improved.
Description
Technical Field
The application relates to the technical field of cosmetic tools, in particular to an animal wool-like polyester silk cosmetic brush hair and a production process thereof.
Background
A cosmetic brush is a common cosmetic tool, and in order to draw a fine makeup, a suitable cosmetic tool, especially a cosmetic brush, is selected, and each cosmetic step is basically performed. The foundation makeup needs a foundation brush, a face-beautifying brush and a blush brush, the fixed makeup also needs a special dense powder brush, and the special eye makeup also needs a specified eye shadow brush. The cosmetic brush has animal hair cosmetic brush and artificial hair cosmetic brush from the class differentiation of brush hair, and animal hair cosmetic brush is soft, but the price is more expensive, and difficult maintenance is difficult for managing moreover, washs at every turn and all can destroy the hair scale, and the brush hair is impaired to reduce cosmetic brush's life, consequently, the present commonly used is artificial hair cosmetic brush.
The related technology is Chinese invention patent with application publication number CN111647971A, which discloses a cosmetic brush hair and a preparation method thereof, the cosmetic brush hair comprises the following components in parts by weight: 10-40 parts of polyethylene terephthalate reclaimed materials, 55-89 parts of polybutylene terephthalate and 0-5 parts of titanium dioxide powder, weighing the raw materials according to the proportion, uniformly stirring, and then carrying out melt spinning, hair cutting, peak grinding and drying to obtain the polyethylene terephthalate recycled material.
In view of the above-mentioned related technologies, the inventors believe that, in the use of the cosmetic brush, the cosmetic brush bristles contact with the cosmetics and the skin, and grease and the like on the cosmetics and the skin adhere to the cosmetic brush bristles, so that the cosmetic brush cannot be washed immediately after use, which easily causes bacteria to grow on the cosmetic brush bristles, and when the cosmetic brush bristles contact with the skin again, skin allergy, acne and the like are easily caused, which results in a drawback that the antibacterial performance of the cosmetic brush bristles is low.
Disclosure of Invention
In order to improve the antibacterial performance of the cosmetic brush hair, the application provides the animal hair-like polyester silk cosmetic brush hair and a production process thereof.

Performance test
And (3) testing antibacterial performance: selecting negative escherichia coli and positive staphylococcus aureus as target test strains; the test is carried out according to AETM E2149-2013a Standard test method for determining antibacterial activity of an antibacterial agent under dynamic contact conditions; and then soaking the bristles in water, taking out the bristles after 10min, drying, and repeatedly testing the antibacterial performance.
Cosmetic brush hair peak appearance rate: randomly extracting 100 bristles, observing the bristles by using a 40-time magnifying glass, counting the number of the bristles without grinding peaks to be recorded as A, and obtaining the peak yield of (100-A)/100 multiplied by 100%.
TABLE 8 results of Performance testing
As can be seen from the combination of example 1 to example 3 and table 8, the graphene oxide/silver prepared in preparation example 2 has the best bacteriostatic effect.
As can be seen from the combination of examples 1 to 5 and table 1, the cosmetic brush bristles prepared by using the polybutylene terephthalate, the polyethylene terephthalate, and the polyarylate together with the polyester resin have a high peak discharge rate and a high discharge rate, are soft, and can improve the comfort of use.
In combination with example 8, comparative example 1 and table 8, it can be seen that the antibacterial agent is not added to the polyester resin, and the prepared cosmetic bristles have a low antibacterial rate, which means that the antibacterial agent is not uniformly dispersed in the raw materials of the cosmetic bristles without adding the polyester resin, resulting in a decrease in the antibacterial rate.
By combining example 8, comparative examples 2 to 4 and table 8, it can be seen that the addition of graphene oxide/silver can significantly improve the antibacterial rate of the cosmetic brush hair, and the reduced graphene oxide and silver have a synergistic effect, so that the antibacterial efficiency of the cosmetic brush hair is improved more significantly.
In combination with example 8, comparative example 5 and table 8, it can be seen that the organic bentonite layers are negatively charged, have higher cation exchange capacity, have stronger adsorption and immobilization effects on bacteria, and have a decreased bacteriostatic rate for the cosmetic bristles added with the organic bentonite, indicating that there is no component for effectively immobilizing bacteria in the antibacterial agent.
As can be seen from the combination of example 8, comparative example 6 and Table 8, the addition of chitosan oligosaccharide can improve the bacteriostatic effect because the chitosan oligosaccharide contains-NH in its molecule2，-NH2Suction H+Formation of-NH3 +，-NH3 +The bacterial colony which is negatively charged attracts each other and wraps the surface of the bacteria, thereby preventing the bacteria from absorbing nutrient substances; in addition, the chitosan oligosaccharide enters the interior of bacterial cells through the osmosis action, the intracellular substances are damaged, and the intracellular proteins are denatured through the action of charges carried by the chitosan oligosaccharide, so that the chitosan oligosaccharide has the bacteriostatic effect.
In combination with example 8, comparative example 7 and table 8, it can be seen that the addition of nano bamboo charcoal powder can improve the bacteriostatic effect because the nano bamboo charcoal powder can absorb water and destroy the humid environment required for bacterial reproduction, thereby improving the bacteriostatic effect.
The present embodiment is only for explaining the present application, and it is not limited to the present application, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present application.
