Abstract

The invention provides a preparation method for nylon wool. The preparation method comprises the following steps: (1) weighing, by weight, 85-95% of polyester and 5-15% of nanometer calcium carbonateand performing uniform mixing; (2) subjecting the mixture of the polyester and the nanometer calcium carbonate to drawing; and (3) performing acid treatment on threads drawn in the step (2) to obtainthe nylon wool. The invention also provides a preparation method for bristles on a cosmetic brush. According to the preparation method for the bristles on the cosmetic brush, one end of the nylon woolis immersed in a cellulose oxidizing agent, wherein oxidation time is controlled according to the length of a bristle peak; and then sharpening, washing and drying are carried out to obtain the bristles of the cosmetic brush. The nylon wool of the invention has high toughness, strong powder dipping strength and uniform powder dipping performance, and can reduce powder consumption.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a preparation method of nylon wool. Background technique [0002] Cosmetic brushes are mainly used in make-up and other fields. Generally, they can be divided into honey powder brushes, blush brushes, eyebrow brushes, eye shadow brushes, eyeliner brushes, eyelash brushes, etc., but the structures of different makeup brushes are mostly similar. Makeup brushes are mainly composed of two parts, namely the handle end and the bristles. The manufacturing materials of traditional makeup brushes are mainly made of wood or organic synthetic materials for the handle end; the bristles are mainly made of synthetic materials such as natural animal hair or artificial nylon hair. The material of the bristles determines the quality and price of the makeup brush. Generally, animal hair has a better touch than synthetic nylon hair, and the makeup effect is more submissive. ...
