Bed brush with which material bristles?

The purpose of the bed brush is to sweep the surface of the bed sheet to remove the floating dust, debris and shedding hair and other things, sweep the bed brush bristles which is a good material, the common bristle materials are nylon, pbt and pp silk these three, the characteristics of these three materials are different, you can choose according to their own needs, the following I would like to introduce you to the difference between the three.

Nylon bristles wear resistance is better, with high temperature, acid and alkali resistance, good resilience, PBT bristles elasticity than nylon, but wear resistance and recovery is not as good as nylon, PBT filament performance is soft, long time use is easy to deformation, polypropylene (PP) bristles, with acid and alkali resistance, but resilience is not very good, long time work is easy to deformation difficult to recover, the price of nylon bristles > pbt bristles > pp bristles.
