Problems solved by technology

The utility model patent "a filter with anti-sticking lip and anti-pollution" is coated with a layer of protective film on the outside of the tipping paper and "a multi-functional tipping paper" with the purpose of anti-sticking lip, fragrance, flame retardant, etc., in the water The outer layer of pine paper is compounded with fruit flavor waterproof layer and protective film layer, but the judgment result of anti-sticking lip is not mentioned
The disadvantage of this evaluation method is that it is completely based on artificial subjective feelings, and the reproducibility is poor; and the results cannot be strictly quantified

Embodiment 1

[0049] In this embodiment, 20 different samples are detected by using the method of the present invention and the existing manual suction evaluation method, and the detection results are shown in the table below. Among them, the manual evaluation adopts multiple groups of coding and dark evaluation, that is, when the evaluation personnel do not know the contact angle of the sample in advance, they divide the same sample into multiple groups of random codes, and let the evaluation personnel evaluate the suction and give the grade: non-sticky lips, light There are five grades of sticky lips, moderate sticky lips, severe sticky lips, and severe sticky lips; among them, the sticky lips are grade 1 for mild sticky lips, grade 2 for moderate sticky lips, grade 3 for severe sticky lips and Grade 4 is severe lip stickiness.

Embodiment 2

[0053] In this embodiment, 20 different samples are also detected by the method of the present invention and the existing manual suction evaluation method, and the detection results are shown in the table below. Among them, the manual evaluation also adopts multiple coded dark evaluations.

[0054]

[0055]

[0056] From the test results of Example 1 and Example 2, it can be seen that the detection method of the present invention is completely consistent with the detection results of manual suction evaluation. The method of the invention can objectively and accurately quantify whether the cigarette tipping paper has lip sticking force, is easy to popularize and apply, and provides a basis for formulating the standard of cigarette sticking lip sticking force.

Abstract

The invention discloses a method for measuring a lip sticking force of tipping paper for cigarettes. The method comprises the following steps of testing a degree of a contact angle theta formed by artificial saliva droplets on the surface of the tipping paper for the cigarettes by using a contact angle tester, and establishing a quantitative relation between the angle of the contact angle theta and the lip sticking force of the tipping paper for the cigarettes, so that the lip sticking force of the tipping paper for the cigarettes can be judged. According to the method, the quantitative relation of the consistency between the measurement result of the degree of the contact angle theta formed by the artificial saliva droplets on the surface of the tipping paper for the cigarette and the lipsticking force of the tipping paper for the cigarette is established for the first time, so that the lip sticking degree of the tipping paper is quantified. Compared with the result of artificial smoking assessment, the reproducibility is greatly enhanced.

Description

technical field [0001] The invention belongs to the technical field of tobacco testing, in particular to a method for measuring the lip sticking force of cigarette tipping paper according to the size of the contact angle. Background technique [0002] Cigarette filter is mainly composed of three layers of acetate fiber, molding paper and tipping paper. Among them, tipping paper, also known as tipping paper, is used to wrap the outside of the filter and stick the filter to the end of the tobacco rod. Tipping paper is a kind of decorative paper obtained by printing, coating and other processing on the tipping base paper. It is usually cork color or opaque white, which can improve the appearance. The tipping paper is in direct contact with the smoker's lips. When the weather is dry, when consumers smoke cigarettes, a small amount of saliva may wet the tipping paper, and it will dry slowly during the smoking process. The saliva protein remaining on the lips It will have a bond...
