Abstract:Cobb method is usually used to measure sizing degree of tipping base paper at present, but this method has some defects, it can’t meet the development trend of the tobacco industry. In this study, from the comparison, analysis and discussion of different sizing degree test methods (Cobb method, dynamic Cobb method, modified Cobb method, EST method and dynamic contact angle method) the causes of the defect of Cobb method was found out. By using modified Cobb method to amend the defect, the testing accuracy was close to EST method, at the same time, it didn’t need to purchase new testing instrument and didn’t increased cost, so the further promotion of this method was recommended. |
