Synthetic fiber is made of PBT(polybutylece terephthalate)  and PET(Polyethylene terephthalate). They are both belong to etroleum by-products


PBT have the advantage of toughness and PET have the advantage of durable, so the mixture can get the best results to make synthetic fiber (brush filament) for brush using.
