Abstract:In order to obtain good yarn quality and raw material utilization rate，the influence of forward and backward cotton feeding on constant speed and variable speed combers and combing waste percentage are analyzed.Optimization and configuration of combing elements are elaborated from the aspects of the requirements of top comb quality，tooth density configuration and operation points，the influence of different combing schemes on the yarn quality，the central angle of the tooth surface and the total combing point of combing cylinder.It is pointed out that the yarn quality is basically the same when the forward and backward feeding methods are used in the constant speed combing machine.Variable speed comber is more suitable for forward cotton feeding process；in the forward feeding process，the top combing affects the total waste percentage by 50%~60%.In the case that the tooth pieces are not embedded，the tooth density and insertion depth should be increased as much as possible to maximize the combing efficiency of the top comb.The key to increase the total combing point of coming cylinder as much as possible under the premise of ensuring the volume and fiber space is to use the cylinder with large or super large central angle of tooth surface.
Key Words:forward cotton feeding；backward cotton feeding；top comb；insertion depth；cylinder；tooth density；total combing point；combing waste percentage
