Which kind of synthetic filamen is suitable for making paint brush？
At the moment, there are two kinds of material for making paint brush. One is pig hair, pig hair are the coarse hairs on the back and neck of a pig, which are strong yet springy. The bristles have natural split-ends (flagged ends), which increases the amount of paint they hold and helps to maintain precision in the brush’s edge or point.
Another one is synthetic bristles, are made from nylon, nylon and polyester are the best for water-based latex paints. That’s because natural bristles brushes will soak up too much water and go limp. Use natural bristle or blended (natural and synthetic) brushes for oil-based paint and finishes.
Water-based latex paints---nylon, synthetic polyester filament
Oil-based painting--natural bristle or bristle blended synthetic
