Effects of lubricant content of tow for cigarette on filter rod making and cigarette quality

Effects of lubricant content of tow for cigarette on filter rod making and cigarette quality were studied.Results indicated that with the increase of lubricant content of tow,uncrimping energy of tow increased;stability of the filter rod increased;characteristic curves of tow upper right migrated.Along with the increase of lubricant content of tow,content of moisture,tar and CO in cigarette smoke decreased slightly while nicotine did not change significantly.In certain pressure drop range,with the increase of lubricant content,the aroma quality could be slightly improved.
