Abstract
The present disclosure provides a method for preparing a porous antibacterial fiber brush. Fiber masterbatch made of ultra-fine reaming silica gel, silver-based antibacterial agent and other materials is melted, drawn, cut, polished and then dried to make the porous antibacterial fiber brush. A large number of micropores are distributed on the surface of the porous antibacterial fiber brush, which absorb cosmetic residues on the skin surface and tiny dirt in the pores, and realize efficient cleaning of the surface of human skin.
Claims10
A method for preparing a porous antibacterial fiber brush, comprising following steps:
- melting and drawing fiber masterbatch and cutting the fiber masterbatch into short fibers;
- wherein the fiber masterbatch comprises following raw materials by fight:
- ultra-fine reaming silica gel provided in an amount ranging from 10-30%, silane coupling agent provided in an amount ranging from 0.5-5%, silver-based antibacterial agent provided in an amount ranging from 0.1-2%, pigment provided in an amount ranging from 0-1%, and thermoplastic polymer provided in balance;
- wherein the thermoplastic polymer is selected from any one or two of polybutylene terephthalate and polyamide.
- uniformly polishing top ends of the short fibers at a temperature ranging from −20° C. to −40° C.;
- ultrasonic cleaning the short fibers and vacuum drying the short fibers;
- and
- transplanting the short fibers on a head of a brush to obtain the porous antibacterial fiber brush.
