TABLE 1 color difference analysis results of filter sticks at the tip
| Sample (I) | dE value before and after aspiration | After suction appearance |
| Example 1 | 1.51 | Does not change color |
| Example 2 | 1.33 | Does not change color |
| Comparative example 1 | 26.88 | Yellowing of |
As can be seen from table 1: the dE value of the common acetate fiber filter stick before and after suction is 26.88, and the appearance of the common acetate fiber filter stick after suction is observed to turn yellow. While the multi-component composite filter stick without the adsorbing material is prepared in example 1, the dE value before and after suction is 1.51, and the appearance after suction is observed to be unchanged, the multi-component composite filter stick with the adsorbing material is prepared in example 1, the dE value before and after suction is 1.33, and the appearance after suction is observed to be unchanged. Compared with the cigarette adopting the common acetate fiber filter stick, the multi-component composite filter stick has better adsorption effect on filter stick dyeing substances such as tar and the like, achieves the effect of no color change after smoking, and improves the smoking sensory quality of the cigarette.
2) The filter rods prepared according to examples 1 and 2 and comparative example 1 under the same conditions were used as experimental samples to perform a resistance-on-draw test on cigarettes, and the results are shown in table 2:
TABLE 2 cigarette resistance
| Sample (I) | Comparative example 1 | Example 1 | Example 2 |
| Suction resistance (Kpa) | 4.0 | 4.6 | 4.4 |
As can be seen from table 2: the maximum difference of the suction resistance of the common filter stick in the embodiment is 0.6Kpa, which does not affect the normal suction. Among them, example 1 has a higher absorption resistance than example 2, which is caused by the larger pore size of the activated carbon than cucurbituril.
3) The filter sticks prepared under the same conditions according to the examples 1 and 2 and the comparative example 1 are used as experimental samples, and after the filter sticks are trapped by a Cambridge filter of a smoking machine, the components of the cigarette smoke are analyzed by GC-MS, and the results are shown in Table 1:
TABLE 3 analysis results of flue gas fraction
As can be seen from table 3: the smoke components of the common filter stick cigarette are not greatly different from those of the embodiment, so that the sensory quality of the cigarette is ensured. And the embodiment 1 and the embodiment 2 have certain adsorption capacity compared with the common filter stick cigarette.
