Polyketone Bristles And Toothbrush Comprising The Bristles

Abstract

Provided are polyketone toothbrush bristles and a toothbrush comprising the same. The toothbrush bristles are made using a polyketone material having high rigidity, high elasticity and excellent wear resistance and thus shows reduced bristle gap-widening and increased service life. The toothbrush bristles obtained by using the polyketone according to the present disclosure have excellent elasticity and are suitable for removal of plaque on the severely indented tooth surfaces. Particularly, in the case of fine bristles, it is possible to remove interdental plaque, which, otherwise cannot be removed well by the conventional toothbrushes.

1 . Toothbrush bristles comprising polyketone. 
     
     
         2 . The toothbrush bristles according to  claim 1 , wherein the polyketone has a basic structure comprising carbon monoxide and olefin. 
     
     
         3 . The toothbrush bristles according to  claim 1 , wherein the polyketone is a hybrid polymer of carbon monoxide with ethylene or a terpolymer of carbon monoxide, ethylene and polyketone. 
     
     
         4 . The toothbrush bristles according to  claim 1 , wherein the polyketone is represented by the following chemical formula:
