Study on the Process Factors Affecting the Combing Quality
In order to improve the combing quality,the comparison of combing quality and yarn quality under two kinds of combing strength shows that the stronger combing has better quali-ty index when the strength index of raw material is better.The influence of the combing prepa-ration process configuration on the combing quality is described,and the control methods of combing cotton neps and short fibers are put forward.The influence and significance of the noil gauge,carding gauge,top comb insertion depth,timing of detaching and overlapping,rack pro-file on combing quality are analyzed.It is pointed out that we should adhere to the overall idea to do the process design,and set up the appropriate combing preparation process.There is a sig-nificant correlation between the specific parameters of combing process and the removal of cot-ton neps and short fibers in combing process,and the adjustment of the process should be com-prehensively considered and accurately set according to the specific characteristics of the feeders and the outstanding needs of the output products.The use of less pre-drawing number,small pre-drawing,drafting multiple of sliver coiling and forward cotton feeding is conducive to the high speed of the comber.Understanding and mastering the development trend of combing cyl-inder and top comb is helpful to exert its best performance.
