Synthetic Hair Makeup Brush factory Nylon wire makeup brush Nylon wool is a hard and flat fiber with a completely flat microscopic surface structure. This is why the powder does not really stick to them; the powder slips off the nylon hair easily. Nylon hair is divided into curved fibers and straight fibers. The bent fiber undergoes special electrical treatment. The hair is wavy, scattered rather than gathered. It is mainly used as a powder brush and blush brush. Straight fibers are also divided into single color, double color and three colors.http://www.kmmakeupbrush.com/s....ynthetic-hair-makeup
