Description

Technical Field

[0001] The present invention relates to a makeup brush and a method for printing patterns thereon, specifically a makeup brush with clear patterns and a method for printing patterns thereon, belonging to the technical field of makeup brush manufacturing. Background Art

[0002] The bristles of makeup brushes are generally divided into two types: animal hair and synthetic hair. Synthetic hair can be classified into sharpened fibers and non-sharpened fibers according to the hair tips. The hair tips of sharpened fibers are slender and soft, and the hair strands have better elasticity than animal hair, do not absorb powder, and are easy to clean, making them suitable for thick paste-like makeup products. Synthetic hair has a harder touch and is not easy to brush the color evenly, but it is durable and easy to clean. For some brushes that require a certain hardness to achieve a better makeup effect, a combination of natural hair and artificial hair is used. In addition to the difference in bristle materials, the brush heads of professional makeup tools also have different sizes and shapes according to the different makeup application parts, presenting various brush head shapes such as arc-shaped, pointed top and beveled or flat mouths. Whether the lines and arcs of the brush head are smooth will affect the makeup application effect, so the brush head shape is also an important factor affecting the makeup application effect.

[0003] In the manufacturing process of traditional makeup brushes, a dyeing process is usually used to add patterns to polyester fibers or animal hair. However, this method has many disadvantages: low production efficiency, insufficient pattern clarity, poor integrity of pattern outlines, and easy environmental pollution during the production process. Therefore, new technologies are urgently needed to solve these problems to improve production efficiency and pattern clarity while reducing environmental pollution. Summary of the Invention

[0004] The purpose of the present invention is to combine special formulated polyester fibers with laser technology to overcome the deficiencies of the traditional dyeing process and provide a makeup brush with clear patterns and a method for printing patterns thereon to achieve high-efficiency and high-clarity pattern printing.

[0005] The present invention achieves the above purpose through the following technical solutions. The makeup brush with clear patterns includes a brush head, bristles, and a pattern or logo printed on the pointed hair tips of the bristles.

[0006] The production process of the bristles of the makeup brush with clear patterns, the production process includes the following steps:

[0007] (1) Material selection, selecting polyester filament makeup brush bristle raw materials;

[0008] (2) Raw material drying, removing moisture from the raw materials to ensure that the raw materials will not affect the quality due to moisture during subsequent processing;

[0009] (3) Cutting into bundles, cutting, combing, bundling, and sorting the extruded and spun polyester filaments into bundles to prepare for subsequent processing;

[0010] (4) sharpening the wool-like polyester filaments and cutting them into bundles into the solution;

[0011] (5) Neutralization and cleaning: soak the sharpened polyester filament in an acidic solution to neutralize the alkali solution remaining in the polyester filament, and then rinse with clean water until the pH value drops to a range of 6 to 9;

[0012] (6) Drying and forming: the polyester yarn after the above treatment is dried to achieve the final shape and performance requirements;

[0013] (7) Wool material: put the wool into a specific wool cup according to the required specifications;

[0014] (8) taking out the shaped wool bale line, taking out the processed wool material, and arranging it into the required shape;

[0015] (9) After measuring, the hair roots are hot cut. According to the design requirements, the hair material is accurately measured and then hot cut to ensure that the size and shape of the makeup brush meet the standards.

[0016] In the technical scheme, the raw materials of the polyester silk cosmetic brush bristles in step (1) include 20% to 70% Ecolon polyester fiber, 10% to 40% nanoparticle additives, 10% to 30% titanium dioxide, and 20% to 70% other polyester resins. The nanoparticle additive is titanium dioxide, pearl powder, silicon dioxide, or a mixture of two or more thereof; the Ecolon polyester resin includes a mixture of PTA, PDO, and PBT.

[0017] In the technical scheme, the polyester yarn cut into bundles in the step (4) is immersed in a sodium hydroxide solution at 85-130° C. and with a concentration of 35%-50% by mass twice; in the first immersion, the polyester yarn is in contact with the sodium hydroxide solution at the tip of the hair and the part where the neck structure is to be formed, and the immersion time is 5-8 minutes; the second immersion is for the entire head, and the immersion time is 90-150 minutes, so as to form the hair peak and the neck structure at the peak tip.

[0018] A method for printing a pattern on a cosmetic brush having a clear pattern, the method comprising the following steps:

[0019] (1) Prepare the brush head;

[0020] (2) Design pattern;

[0021] (3) Laser treatment;

[0022] (4) Complete the pattern addition.

[0023] In the technical solution, the step (1) uses a makeup brush head made of the above-mentioned special formula polyester fiber makeup brush bristles.

[0024] In this technical solution, in step (2), the required pattern is designed according to requirements, and the pattern can be of any shape to meet different market demands.

[0025] In this technical solution, in step (3), a laser device is used for pattern printing. Before printing, a tray is prepared for placing the brush head. The tray is provided with grooves and the brush head is snapped into them. Before printing, it is detected and adjusted so that all the bristles are arranged upwards. The tray with the fixed brush head is placed on the laser device, and the laser is used to move to perform laser printing on each row of brush heads.

[0026] In this technical solution, in step (3), the laser device needs to use a low-power cold laser with ultraviolet or green light, and the power range is within 3 - 10 watts. Excessive laser power may cause the problem of burning the hair peaks. Therefore, it is necessary to strictly control the laser power and time.

[0027] In this technical solution, in step (4), through laser treatment, the pattern is precisely printed on the pointed hair peaks of the makeup brush, forming a clear and beautiful pattern.

[0028] The beneficial effects of the present invention are as follows: Compared with the traditional technology, the application of laser technology in this patent application greatly shortens the time for pattern printing, improves production efficiency. By combining special formula polyester fiber with laser technology, the pattern is clearer and has a higher contrast. Compared with the traditional dyeing process, laser technology does not use chemical dyes, reducing environmental pollution during the production process. By combining special formula polyester fiber with laser technology, adding patterns on the pointed hair peaks has the advantages of high production efficiency and clear patterns, and has a wide application prospect. The present invention not only improves the aesthetics and practicality of makeup brushes, but also provides an environmentally friendly and efficient production method for the makeup brush manufacturing industry.
