Embodiment Construction

[0025] refer to figure 1 , the present invention provides a bristle with a plurality of hair peaks 2, which includes a bristle body 1, and the end of the bristle body 1 has two or more hair peaks 2.

[0026] Since the production of the bristle peaks 2 is usually achieved by oxidation, in order to realize multiple oxidized peaks 2 at one time, preferably, the end of the bristle main body 1 is provided with a number of concave positions 4 corresponding to the hair peaks 2 to form two One or more than two outward expansion heads 3, each of the outward expansion heads 3 forms a hair peak 2. Moreover, the concave position 4 extends along the length direction of the bristle body 1 so that the surface of the bristle body 1 presents several concave stripes. Such as figure 2 As shown, when the double peak is set, the cross section of the bristle body 1 is in the shape of "8"; as image 3 As shown, when it is set as three peaks, it can be set as three parallel expansion heads 3, or ...

Abstract

The invention discloses bristles, a cosmetic brush, a bristle preparation method and a bristle extrusion mold. The cosmetic brush comprises a brush rod and a brush head, the bristles are arranged on the brush head, and two or more bristle peaks are arranged at the tail end of each bristle; the preparation method sequentially comprises the steps of resin drying, extrusion spinning and oxidation peak appearing; the extrusion mold comprises a mold body which is provided with multiple extrusion ducts running through the mold body, multiple protruding positions are arranged on the inner walls of the extrusion ducts by protruding in the circumferential direction, multiple concave positions are formed in the surface of a product through the protruding positions, and multiple expanding heads are formed at the end of the product through the concave positions. Accordingly, the two or more bristle peaks are arranged at the tail end of each bristle, the bristles of the produced cosmetic brush is more delicate, soft and comfortable in touch feeling, the spacing between the two adjacent bristle peaks is reduced, the peak shape is stiffer and more durable, the surface area of the bristles is increased, the smoothness of the bristle peaks is improved, the powder collection degree is higher, use is comfortable, and practicability is high.

Description

technical field [0001] The invention belongs to the field of cosmetic brush tools, and in particular relates to a bristle, a cosmetic brush using the bristle, a preparation method for producing the bristle and an extrusion die. Background technique [0002] Cosmetic brushes generally include a brush shaft and a brush head formed of bristles set at one end of the brush shaft. Cosmetic brush bristles are generally divided into animal hair and nylon hair. Animal hair cloth has complete hair scales, so the hair is soft and saturated with powder , can make the color uniform and docile, and does not irritate the skin, but its price is expensive; while the texture of nylon wool is hard and the touch is not good. [0003] Restricted by factors such as the material and price of animal hair, nylon hair is more commonly used in the market. In order to improve the problem of poor touch caused by the hard texture of nylon bristles, in the traditional process, after extruding cylindrical...
