The Analysis of Advantages and Disadvantages of Carding Process with Adjustment of Noil Rate

In order to improve quality of cotton sliver,analysis is done to the analysis of advantages and disadvantages of carding process with adjustment of waste rate,comparing test proves that in fore spinning process,the blowing-carding combination,carding and combing processes improve quality of sheet and cotton sliver through the increase of the waste rate,causing cost increase,yet when a certain range exceeded,it goes the opposite and can not improve the combed sliver quality.It is pointed out that the loss of improving the quality of sliver though increase of the noil rate outweighs the gain.The relevant norms is needed including strictly control the quality of raw materials,carding accessories,production environment,process adjustment.Control should be starts with the types of carding accessories,specifications,manufacturing precision and the carding process.Only by doing so,can carding cost be reasonably controlled with high combing efficiency and good carding effect.
