Brush and its production manner for anti-bacterial Characteristic make-up

摘要

The invention provides an antibacterial cosmetic brush which protects ecological environment of the earth, is sanitary and safe and maintains antibacterial property for a long time. anti-bacterial make-up brush is a make-up brush whose brush bristles are formed of synthetic fibers. The brush bristles contain 20 pts.wt synthetic fiber containing an inorganic antimicrobial agent in 100 pts.wt brush bristles and the synthetic fiber containing the inorganic antimicrobial agent contains 0.02-3 pts.wt inorganic anti-bacterial agent in 100 pts.wt. In manufacturing this make-up brush, 30-1 pts.wt inorganic antimicrobial agent is mixed with 70-90 pts.wt resin of one kind selected from thermoplastic resins and molten and dispersed. After that, a master batch is manufactured by extrusion molding, and subsequently the master batch is mixed with thermoplastic raw material resin and molten and dispersed. After that and the mixture is subjected to spinning to thereby make a brush bristle. The master batch is mixed so that 0.02-3 pts.wt inorganic antimicrobial agent is contained in 100 pts.wt brush bristle.
