Title:
METHOD FOR MEASURING LIP ADHESION FORCE OF CIGARETTE TIPPING PAPER ACCORDING TO COLOR FASTNESS
Document Type and Number:
WIPO Patent Application WO/2022/099901
Kind Code:
A1
Abstract:
Disclosed in the present invention is a method for measuring a lip adhesion force of a cigarette tipping paper, comprising the following steps: under an artificial saliva infiltration condition, tightly attaching a cigarette tipping paper to specimen glass fiber papers; under a load condition for a period of time, testing a color difference between the specimen glass fiber papers and a blank glass fiber paper to obtain color fastness levels of the specimen glass fiber papers; and then establishing a quantitative relationship between the color fastness levels and a cigarette lip adhesion force to determine the size of a lip adhesion force of the cigarette tipping paper. Compared with results of manual smoking evaluation, the measurement method of the present invention has greatly improved reproducibility.
