Analysis of "soft combing" of cotton comber based on fiber breakage

When cotton comber is carding at high speed,fibers damage and breakage will be caused by its cylinder carding,which influences the combing quality.Therefore,based on the analysis of average carding force of single fiber in the process of combing as well as the breaking strength of cotton fiber under ideal conditions,this paper,aiming at the cotton fiber breakage,constructs a maximum theoretical velocity model of cotton comber,i.e.calculation model of ″soft combing value″.And,combining with the field experiments,a new concept of ″soft combing ratio″ is proposed according to short fiber content variation before and after cylinder combing.In conclusion,the concept of ″soft combing″ is proposed,i.e.the combing that the speed of cotton comber is lower than the ″soft combing value″ and the soft combing ratio is in a reasonable range is defined as ″soft combing″.This study provides a theoretical foundation for the development of new type of high-speed cotton comber and the improvement of combing quality.
