Bristle head of cosmetic brush and method for manufacturing bristle head of cosmetic brush

Abstract

The invention provides a bristle head of a cosmetic brush. The bristle head comprises a bristle peak part, the bristle peak part is composed of nylon PA polyamide. The bristle head further comprises amelt adhesive bonding layer wrapping the tail of the bristle peak part at 360 degrees, and the melt adhesive bonding layer is formed by carrying out heating on nylon PA polyamide powder and a plasticfoaming agent, namely, azodicarbonamide powder at the temperature of 290-300 DEG C. For the bristle head of the cosmetic brush provided by the invention, a metal sleeve part is saved, so that the structure of the bristle head of the cosmetic brush is simplified, the firm fixing for the bristle peak part is also realized, therefore, the phenomenon of bristle separating and falling of the bristle peak part is obviously improved, and further, the service life of the bristle head of the cosmetic brush is prolonged. The invention further provides a method for manufacturing the bristle head of thecosmetic brush. The processing technology is simple and is easy to implement, the production efficiency is high, the production cost is low, and the manufactured bristle head of the cosmetic brush ismild and free of stimulation, and has the good environmental protection property.

Description

technical field [0001] The invention relates to the technical field of cosmetic product processing, and more specifically, to a cosmetic bristle head. The invention also relates to a method of manufacturing a cosmetic bristle head. Background technique [0002] As we all know, the makeup brush head is the most critical part of the makeup brush. The quality of the makeup brush head directly determines the makeup effect and the service life of the makeup brush. [0003] At present, the cosmetic brush heads on the market are usually composed of hair peaks, gelatinous lumps and plastic or metal mouth tubes. Because the gelatinous lumps are easy to dry and become brittle, they are easy to crack after long-term use. Therefore, the hairy peaks are not installed firmly. Prone to shedding and shedding. In addition, the cosmetic bristle head in the prior art has many components and high production cost. [0004] At present, there are mainly two types of shaping processes for cosmet...

AI Technical Summary

Problems solved by technology

If the first setting process is adopted, the glue will take a long time to dry, and during the bonding process, the glue will easily emit harmful gases, which will endanger the health of the body; if the second setting process is adopted, the agglomeration will easily lose its flexibility, resulting in Cracks and faults will cause hair loss after a long time, and the rate of defective products is high. In addition, thick smoke is emitted during high-temperature ironing, and additional equipment needs to be added, which consumes too much energy and costs too much.
