Problems solved by technology

In addition, some large tipping paper manufacturers in China also pay attention to the lip-smoothing performance during production. However, due to the limitations of technology and level of most domestic tipping paper factories, the lip-soothing properties of the tipping papers produced It is uneven. Experimental studies have found that a considerable part of cigarette filters have lip sticking, that is, poor lip-thinning performance.
[0003] At present, as an important parameter for evaluating the quality of tipping paper, there is no relatively accurate and mature method for testing and evaluating the performance of tipping paper. Therefore, it is necessary to explore an intuitive, accurate and convenient test and evaluation method to measure The lip-thinning performance of the paper, thereby reducing the occurrence of the filter sticking to the lips when the cigarette is smoked

Embodiment 1

[0041] Take a flat piece of cigarette tipping paper and cut it into a 2cm×2cm sample with a paper knife. When cutting, avoid the perforated area. Place the sample with the printed side down and put it in the diluted 1:3 ratio. In the evaporating dish of the ink, use a stopwatch to time the time. After 15 seconds, take out the sample, place the sample printed side down on a clean absorbent paper, and after natural air drying, place the sample flat between two clean glass plates, and use the lens to perpendicular to the sample surface The camera takes a clear picture of the unprinted surface (distal lip surface) of the sample, and uses metallographic analysis software to segment the taken sample photos to separate the unprinted surface (distal lip surface) of the tipping paper sample to be colored. The ratio of the area of ​​the colored area to the area of ​​the sample is calculated to be 10%.

Embodiment 2

[0043] Take a flat piece of cigarette tipping paper and cut it into a sample of 1cm×2cm with scissors. When cutting, avoid the perforated area. Place the sample with the printed side facing down and place the sample with 30% zinc chloride (ZnCl2). ) In the evaporating dish of the solution, use a stopwatch to time the time, take out the sample after 10 seconds, dry the sample in a drying oven, place the dried sample in the middle of two clean glass plates, and use the lens to connect perpendicular to the sample surface The computer's camera obtains a clear picture of the unprinted surface (distal lip surface) of the sample, and uses professional image analysis and processing software to segment the taken sample photos to separate the unprinted surface (distal lip surface) of the tipping paper sample that is colored , Calculated that the area of ​​the colored area accounts for 30% of the sample area.

Embodiment 3

[0045] Qualitative analysis of the lip sparse performance of 5 tipping paper samples: Take one sample from 5 samples and cut it into a 1cm×2cm sample with scissors. When cutting, avoid the perforated area and place the sample with the printed side facing down. In a beaker with Herzberg stain solution, use a timer, take out the sample after 30 seconds, dry the sample in a drying oven, place the dried sample in the middle of two clean glass plates, and use the lens to perpendicular to the sample surface The camera connected to the computer obtains a clear picture of the unprinted surface (distal lip surface) of the sample, and uses professional image analysis and processing software to segment the taken sample photos, and separate the unprinted surface (distal lip surface) of the tipping paper sample is colored Repeat the above steps to obtain colored photos of 5 samples, observe the area of ​​the colored areas, and qualitatively analyze the pros and cons of the lip thinning perfo...

Abstract

The invention discloses a method for testing and evaluating de-lipping performance of cigarette tipping paper. The method comprises the following steps of: firstly carrying out a permeation coloring treatment on a cigarette tipping paper sample; acquiring an image and carrying out an image analysis treatment; quantitatively measuring an area of the colored region; and evaluating the de-lipping performance of the cigarette tipping paper by using the proportion of the area of the colored region to the total area of the sample. According to the invention, the de-lipping performance of the cigarette tipping paper can be visually inspected and the de-lipping performance of the cigarette tipping paper can be characteristically and quantitatively analyzed simultaneously; and in addition, the method for testing and evaluating the de-lipping performance of the cigarette tipping paper provided by the invention has the advantages of simple and convenient method, simplicity in operating and easiness for popularization.

Description

Technical field [0001] The present invention relates to the technical field of performance evaluation of tipping paper for cigarettes, in particular to a method for testing and evaluating the lip thinning performance of tipping paper for cigarettes. The method can quantitatively test the lip thinning performance of tipping paper for cigarettes. Background technique [0002] Cigarette tipping paper is a special packaging paper on the outermost layer of the cigarette filter rod, which is used to connect the filter tip to the cigarette stick. When smoking cigarettes, the lips of the smoker will inevitably touch the tipping paper for cigarettes. For cigarette smokers, the filter part of the cigarette sticks to the lips, which will have a great impact on the smoking experience In severe cases, it will stick the skin on the lips, causing certain injuries to the sucker. Lip release performance is used to describe the ability of the smoker's lips to not stick together when they are in c...
