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 piece of flat tipping paper for cigarettes, cut it into a sample of 2cm×2cm with a paper knife, avoid the perforated area when cutting, put the printed side of the sample down into a 1:3 diluted In the evaporating dish of the ink, use a stopwatch to time, take out the sample after 15s, put the sample printed side down on a clean absorbent paper, after natural air drying, place the sample between two clean glass plates to flatten, and use a lens to vertically sample the surface The camera obtains clear photos of the unprinted surface (far lip surface) of the sample, and uses the metallographic analysis processing software to segment the sample photos taken to separate the colored area of ​​the unprinted surface (far lip surface) of the tipping paper sample, 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 piece of flat tipping paper for cigarettes, cut it into a sample of 1cm × 2cm with scissors, avoid the perforated area during cutting, and put the sample printed side down into 30% zinc chloride (ZnCl2 ) solution in the evaporating dish, use a stopwatch to time, take out the sample after 10s, dry the sample in the drying oven, put the dried sample in the middle of two clean glass plates and flatten it, use the lens perpendicular to the surface of the sample to connect The camera of the computer acquires clear photos of the unprinted surface (far lip surface) of the sample, and uses professional image analysis and processing software to segment the captured sample photos to separate the colored area of ​​the unprinted surface (far lip surface) of the tipping paper sample , the ratio of the area of ​​the colored area to the area of ​​the sample is calculated to be 30%.

Embodiment 3

[0045]Qualitative analysis of the lip-thawing performance of 5 tipping paper samples: take a sample from 5 samples, cut it into a 1cm×2cm sample with scissors, avoid the perforated area when cutting, put the sample printed side down into the packaging In a beaker with Herzberg stain solution, use a timer, take out the sample after 30s, dry the sample in a drying oven, place the dried sample in the middle of two clean glass plates and flatten it, and use a lens to vertically sample the surface The camera connected to the computer obtains clear photos of the unprinted surface (far lip surface) of the sample, and uses professional image analysis and processing software to segment the sample photos taken, and separates the unprinted surface (far lip surface) of the tipping paper sample to be colored Repeat the above steps to obtain coloring photos of 5 samples, observe the area of ​​the coloring area, and qualitatively analyze the pros and cons of the lip-thinning properties of the...

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 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, which can quantitatively test the lip-thickening performance of tipping paper for cigarettes. Background technique [0002] Cigarette tipping paper is the special packaging paper for the outermost layer of the cigarette filter rod, which is used to connect the filter tip and the cigarette stick. When smoking a cigarette, the smoker's lips 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, the skin on the lips will be glued off, causing certain harm to the smoker. The lip release property is used to describe the ability of the smoker's lips not to stick together when they come into c...
