The cosmetic brush made of the imitated animal hair polyester yarn cosmetic brush hair has the advantages of natural coloring, good powder absorbing and releasing effects, texture and functionality comparable to those of animal hair yarn, and environment-friendly materials.
Description
Technical Field
The invention belongs to the field of bristles for cosmetic brushes, and particularly relates to animal-like bristles for a high-end cosmetic brush.
background
The cosmetic brush hair on the market at present is divided into two types: natural animal hair and synthetic polyester bristles.
the cosmetic brush made of natural animal hair has the advantages of good powder absorbing and releasing effects and natural coloring, so that the natural animal hair is frequently used in the prior high-end cosmetic brush. The natural animal hair has the following problems when used as a cosmetic brush hair: firstly, because the natural animal hair is composed of protein, the natural animal hair has the defects of poor antibacterial property, easy damage in the using process and short service life; secondly, as society develops, the demand for cosmetic brush hairs is increasing, but the source of high-quality natural animal hair is decreasing. The animal hair used by the high-end cosmetic brush is derived from free-range animals and wild animals, the number of rural breeding scattered households is greatly reduced along with the improvement of the living standard of people and the proposal of national policy of building beautiful villages, and meanwhile, as the breeding animals are fed by feed, the growth cycle of the animals is shortened, so that the hair quality of the animals is deteriorated, and the animals are easy to break and fall; thirdly, the use of a large amount of animal hair is not favorable for harmony and coexistence of human and animals, and does not conform to the concept of protecting ecological environment. In conclusion, the animal hair has limited resources and unstable quality, so the requirement of the cosmetic brush industry for the hair filaments cannot be met.
The synthetic polyester bristle is made of polybutylene terephthalate (PBT) monofilament. The bristles made of the PBT monofilaments have the advantages of good antibacterial property, fine touch, smooth toughness, long service cycle and smooth surface, and are suitable for making bristles for foundation brushes; but simultaneously, due to the characteristics of PBT, the prepared brush hair has the defects of low powder sticking rate and poor powder releasing effect when being used for a cosmetic brush, and is not suitable for powdery cosmetics; the hair silk with larger curvature is adopted for mixing hair, although the powder sticking rate is improved, the powder is easy to fall off in the cosmetic process after the cosmetic brush is made, and the cosmetic brush cannot really replace high-quality animal hair.
In conclusion, the development of the animal hair-like polyester yarn which has texture close to natural animal hair, has good effects of coloring the animal hair naturally, absorbing and releasing powder, and has the advantages of fine touch, smooth toughness, good skin, environment-friendly material, long service life and the like of the PBT monofilament has important significance.
