Question

which plant used to make bristles of brushes

Answer 1

Natural Bristles are made of animal hair such as hog.

 

Synthetic Bristles are made of Nylon, Polyester or sometimes a mix of both. Coconut fiber is also used commercially for body brushes and brooms because of the softness and the lack of elasticity in the fiber present.

 

So, generally for plants, coconut is used to manufacture bristles of brushes.
