Abstract

The invention relates to a method for measuring the color fastness to saliva of tipping paper for a cigarette. The method is characterized by comprising the steps of sticking the tipping paper sample with glass fiber paper soaked by simulated saliva to form a combined sample, and placing the combined sample under the pressure of a 1kg of load at the temperature of 40 DEG C; evaluating staining degree of the glass fiber paper by a colorimeter. The method is capable of better simulating the contact process between the oral cavity of the human body and the tipping paper on a cigarette filter, and is simple to operate and rapid in measurement speed; compared with a grey scale visual observation method, the method adopts the colorimeter for evaluating the staining fastness degree, so that the results are more objective and accurate, the interference of subjective mood and objective environment of people can be avoided, and the reproducibility is good.

Description

[0001] technical field [0002] The invention belongs to the technical field of physical and chemical index analysis of cigarette materials, and in particular relates to a method for measuring the color fastness to saliva of cigarette tipping paper. Background technique [0003] Cigarette tipping paper is used as a mouth-contact material, and its printed surface is in direct contact with the human oral cavity. When consumers smoke cigarettes, they may be soaked in saliva and under the pressure of lips and teeth, which may cause fading or fading, thus affecting the appearance of cigarette products. In recent years, the production process and printing technology of cigarette tipping paper have become more and more diversified, and various new materials have been continuously applied. If the color fastness to saliva of the tipping paper does not meet the standard, it will inevitably lead to consumers swallowing dyes and being injured, and directly Affect the safety of cigarette...
