Abstract:In order to improve the quality of hemp/cotton combed yarn and solve the problem of excessive dropping hemp and big fiber damage in combing process，according to the properties of hemp/cotton blended raw materials and combing process characteristics，the optimum design of the integral cylinder and top comb for the hemp/cotton combing machine is described in detail.Using hemp/cotton 40/60 blended combing small volume as raw materials，the single factor test method is used to design the test scheme，and the effects of different top comb tooth density and different total teeth number of integral cylinder on combed sliver，dropping cotton（hemp）rate and yarn index are compared and analyzed.It is pointed out that the selection of top comb tooth density should be based on combing small volume hemp/cotton blended ratio，and the matching of combed cylinder and top comb should be based on the dropping hemp rate，yarn neps and hemp grain quality index.GJX-E-90-TP28 integral cylinder matching GJD-E-240-P top comb should be selected for low dropping cotton (hemp) rate of hemp/cotton 40/60 blended spinning，GJX-E-90-J integral cylinder and GJD-E-260-B top comb should be used to control the quality of neps and hemp grains.It is beneficial to improve the combed sliver，yarn quality and
hemp fiber content by carrying out the research on the key technology of hemp/cotton blended spinning，selecting the integral cylinder and top comb combined with combed quality and recommended scheme.
Key Words:hemp/cotton blended spinning；combing；cylinder；top comb；total teeth number；tooth density；evenness CV；dropping cotton rate；dropping hemp rate
