Effect of pin carding plate on fiber length distribution

To discuss the effect of pin carding plate on fiber length distribution in the card slivers,length tests to the card slivers under different carding plate gauge,taker-in speed and doffer speed using pin carding plate and saw-tooth carding plate under the card taker-in by USTER AFIS single fiber tester were done.The results show that compared with saw-tooth carding plate,carding action of pin carding plate is more gentle,which is favorable to reducing fiber damage as a whole,especially when the gauge is small.Compared with installing taker-in grid,the taker-in installed carding plate is favorable to improving fiber length distribution in the card sliver as a whole.
