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
