   How we tapered our filament and control our tapering?  


Yangzhou Jingdu Brush  Co.,Ltd is a factory who are producing bristle and brush filament. At  the moment, we have two ways to tapered our filament, one is physical  tapered , and one is chemical tapered filament.  


Let’s introduce how we make chemical tapered filament:  


1. Different sharp of  filaments will use different degree of acid-base concentration. We will  measure the degree of acid accordingly to kinds of filament  

2. Put the filaments in the acid water in a certain position  

3. After boiling,  checking how much they have reflected and keep watching until they have  finished, and washed them to measure the size to check if it is ok  

4. Put the finished tapered filament in the accurate place.  


The most important is  that to pay more attention to degree of acid-base concentration, if too  high, then the filament would be shorted.  


Skilled and trained Workers are more necessary for making chemical tapered filament.
