As shown in the reference Table 2, the smoke resistance of the composite filter stick cigarette is not higher than 1200Pa, and compared with the comparative example 1 of the common acetate fiber filter stick cigarette with the same specification, the smoke resistance of the composite filter stick cigarette in examples 1-4 is improved, but the ventilation rate and the total ventilation rate of the filter stick are improved.
The filter sticks prepared in examples 1-4 and comparative examples 1-2 were prepared into cigarettes, and the amounts of nicotine and tar in the mainstream smoke in the cigarettes were tested and are shown in reference to table 3.
TABLE 3 Table 3
Referring to table 5, compared with comparative example 1, it can be seen that the amount of nicotine and tar in the main stream smoke of the composite filter rod cigarette is reduced by about 36% on average, and the amount of tar is reduced by about 54% on average, compared with the common acetate filter rod, the smoke component filtration efficiency is improved with the increase of smoke resistance, and the removal rate of nicotine and tar in smoke is improved by step filtration.
Comparative example 2 has a less pronounced effect on the reduction of nicotine and tar levels in the mainstream smoke than comparative example 1, but has a poor filtration effect.
The filter rods prepared in examples 1 to 4 and comparative examples 1 to 2 were further prepared into cigarettes, and the release amounts of 7 representative harmful components in the mainstream smoke and the hazard index of the cigarettes were measured, and the results are shown in reference to tables 4 (1) and 4 (2).
The hazard index H is calculated by the following formula:
H＝(XCO/14.2+XHCN/146.3+XNH3/8.1+X Crotonaldehyde /18.6+X Phenol (P) /17.4+XNNK/5.5+X Benzo (E) benzo (E [a]
Pyrene (pyrene) 10.9) 10/7, wherein X CO is the measured value of the CO release amount in the main stream smoke of the cigarette; x HCN is the actual measurement value of the release amount of HCN in the main stream smoke of the cigarettes; x NH3 is the measured value of NH 3 release amount in main stream smoke of cigarettes; x Crotonaldehyde is the measured value of the release amount of crotonaldehyde in main stream smoke of cigarettes; x Phenol (P) is the actual measurement value of the release amount of phenol in the main stream smoke of the cigarettes; x NNK is an actual measurement value of NNK release amount in main stream smoke of the cigarette; x Benzo (E) benzo (E [a] Pyrene (pyrene) is the actual measurement value of benzo [ a ] pyrene release amount in main stream smoke of cigarettes.
Table 4 (1)
Table 4 (2)
Referring to tables 4 (1) and 4 (2), the cigarette samples of the composite filter rod showed a reduction in 7 harmful components and a reduction in the cigarette hazard index to 6 or less, compared with comparative example 1. The CO reduction rate is more than 60%, the HCN reduction rate is more than 40%, the ammonia reduction rate is more than 15%, the crotonaldehyde reduction rate is more than 10%, the phenol reduction rate is more than 30%, the NNK reduction rate is more than 70%, and the benzo [ a ] pyrene reduction rate is more than 25%.
Comparative example 2 has a lower harmful component content than comparative example 1, although the harmful component content in 7 was reduced, and the filtering effect of the harmful component was poor.
In conclusion, the composite filter stick cigarette has good tar and harm reducing effects.
The foregoing is merely exemplary of the present utility model and is not intended to limit the present utility model. Various modifications and variations of the present utility model will be apparent to those skilled in the art. Any modification, equivalent replacement, improvement, etc. which come within the spirit and principles of the utility model are to be included in the scope of the claims of the present utility model.
