Fiber can be used on any makeup brush. It is different from animal hair. It can partially replace animal hair, but not completely.
Fiber is plastic particles after high temperature melting wire forming, belongs to industrial products, basically is a standardized product. The focus of fiber is mainly reflected in: plastic particles, drawing process and curvature, oxidation peak, dyeing process, curvature and curvature ratio. On the market, many bionic hair and other names are essentially fiber.
Plastic particles: raw materials for wire drawing, PBT and PET, PET is commonly used as plastic wrap. PET is soft, but PBT has better toughness and strength. These two raw materials are divided into domestic and imported. Imported are generally the use of BASF particles, but Xiaobian has heard of better raw materials from Mitsui and Mitsubishi, basically only the Japanese brand useful to. Generally, it is very good to use BASF. Xiaobian is very responsible to tell you that if you buy a brush that is not on the price, it is a large probability that you do not use BASF's raw materials. Basically, you can use Yanshan petrochemical and Yizheng petrochemical. The price of fiber is only reflected in the raw material, the rest is to increase the degree of comfort, such as more skin-friendly texture.
Drawing process: Drawing process is mainly reflected in the uniformity of thickness, toughness and tensile strength of the fiber. There is not much difference between manufacturers in this respect. The big difference is that the good factory has the quality assurance in the use of materials. The same process, the fiber effect of the good material is definitely better. The second is that the curvature is produced in the drawing process. The curvature is to imitate the real animal hair, we found that animal hair is not very straight, in addition, animal hair has fur scales, sticky powder effect is better; The fiber does not have a hairy scale structure, so it can only be obtained by the curvature of the powder effect, not the larger the better, but there is an applicable standard.
Peak oxidation: Generally speaking, after cutting the filament to the desired length, it needs to be corroded by sodium hydroxide solution to obtain the fiber with peak. Temperature, dosage, time and other factors have a great impact on the peak, bending, peak breaking, uneven thickness and other adverse conditions are common to affect the use of experience. We have also heard of the so-called machine grinding out the peak, for this technology, this is a concept, the current speculation of the ingredients.
Dyeing process: This is very important, related to the beauty of the fiber. Some people say that what dyeing materials to use, pollution-free, pure plant, consumers should think about, pure plant is difficult to dye, or difficult to maintain a fixed color, and solid color with what solid color, also use chemical raw materials. Just like people wear clothes, except natural materials such as cotton, basically are chemical fiber clothes, basically are dyed. There is little wrong with the state of the art now, but consumers may be more comfortable with the clothes they pay a premium for.
Curvature and curvature ratio: Curvature is formed when drawing, and the proportion of curvature is obtained after many tests, Z suitable for Z comfortable bristle scheme. The ratio of the test, the general big brand makeup brush brand will test, so as to guide the manufacturers. Many manufacturers of makeup brushes only know that they are produced for the production of makeup brushes, and they do not know that the bristles are curved.
In terms of the overall fiber, cheap brush, it is difficult to use good fiber, of course, expensive makeup brush to consumers to use, to distinguish, but we still do not want to coax cheap and bad business road.
