In order to study the change rule in the combing waste percentage,neps,and fiber elimination rate of different carding areas in cotton comber cylinder,a 5-zone integrated cylinder was used,and combing experiments were conducted using 5 carding area,4 carding area,3 carding area,2 carding area and 1 carding area,respectively.The combing waste percentage,neps content in cotton noil,and fiber length distribution were obtained for 5 different experimental schemes.The resulting formula was used to calculate the waste percentage of different carding areas,the nep elimination rate and fiber elimination rate of different lengths.The results showed that the change rule in combing waste percentage,nep elimination rate and fiber elimination rate of different lengths in the five different carding areas were basically same,with the second carding area being the largest,followed by the third carding area,the first carding area,the fourth carding area,and the fifth carding areas,respectively.In the same carding area of the cylinder,when the fiber length was smaller than the fiber bundle length outside the nipper mouth,the shorter the fiber length was,the higher the exclusion rate will be.When the fiber length was greater than the fiber bundle length outside the nipper mouth,the fiber elimination rate showed the trend of decrease with the increase of fiber length,and it had a certain fluctuation.The carding gauge and the depth of the cylinder needle were important parameters that affected the carding effect.
