Definitions

  • an object of the invention is to provide a cigarette paper which can reduce a visible sidestream smoke amount and at the same time can reduce a carbon monoxide amount in a mainstream smoke.
  • the shape of the primary particles of calcium carbonate to be used is not particularly limited, and the primary particles having any shape of a spindle shape, a cubic shape, a columnar shape, and a needle shape can be used.
  • the primary particles having a columnar shape or a needle shape when calcium carbonate in which the primary particles have a columnar shape or a needle shape is used, the amount of carbon monoxide in mainstream smoke is significantly reduced in comparison with the case of using calcium carbonate having another shape.
  • the scattered light intensity detection unit 14 is provided in itself with a well-known optical system (not shown) used for collecting the 90 degree scattered light SVL and has a photoelectric converter (not shown) which converts the collected 90 degree scattered light SVL into an electrical signal and outputs the electrical signal.
  • a photoelectric converter a photomultiplier which converts light into a voltage signal can be preferably used.
  • the converted voltage signal is subjected to analog-to-digital conversion, for example, and then can be subjected to data sampling with a personal computer.
  • Data acquisition interval and acquisition time can be arbitrarily set, and typically measurement at 300 points can be performed at an interval of 0.2 seconds for 1 minute.
  • the visible sidestream smoke amount measuring apparatus preferably has conversion table means 20 that converts the 90 degree scattered light intensity detected by the scattered light intensity detection unit 14 into the amount of visible sidestream smoke and outputs the amount of visible sidestream smoke based on a correlative relationship between the 90 degree scattered light intensity and the amount of visible sidestream smoke.
  • the conversion table means the correlative relationship between the 90 degree scattered light intensity obtained in advance and the amount of visible sidestream smoke is input as a conversion equation, a calibration curve, and so on, a 90 degree scattered light intensity signal output from the scattered light intensity detection unit 14 is converted into the amount of visible sidestream smoke, and the amount of visible sidestream smoke is output.
  • each longitudinal width of the observation windows 311 and 321 corresponds to the height of the visible light beam emitted from the visible light emitting unit 12 of the visible sidestream smoke amount measuring apparatus, and the distance from the cigarettes CIG1 and CIG2 to the lower ends of the observation windows 311 and 321 corresponds to a distance from the smoking article SA at the lower end of the visible light beam emitted from the visible light emitting unit 12 of the visible sidestream smoke amount measuring apparatus.
  • the visible light from the visible light sources 33 and 34 is applied from above to the sidestream smokes SS1 and SS2, and the sidestream smokes SS1 and SS2 are observed only from the observation windows 311 and 321.
  • calcium carbonate PCX-850 and Cal-light-SA were purchased from Shiraishi Kogyo Kaisha, Ltd.
  • needle-shaped calcium carbonate and bur-shaped calcium carbonate were purchased from Newlime Co., Ltd.
  • This cigarette paper is matched for two or more days under conditions of a temperature of 22°C and a relative humidity of 60% and cut into a predetermined length.
  • ultrasonic extraction is performed for 30 minutes in 0.3 N aqueous hydrochloric acid, and calcium carbonate is quantified as calcium ions by a capillary electrophoresis system (7100) manufactured by Agilent Technologies, and calcium ions are converted into calcium carbonate, whereby the amount of calcium carbonate in the cigarette paper is obtained.
  • the length (L) of the primary particle described in Table 2 is an average of the length (L) of 100 primary particles measured by means of Winroof image analysis software (Mitani Corporation) using an SEM image captured with a JSM-5310 scanning electron microscope manufactured by JEOL. Although the aspect ratio of calcium carbonate used in this example is indicated in Table 2, the width (W) of the primary particle is measured in a similar manner to the length (L) of the primary particle, and the ratio (L/W) of the length (L) of the primary particle to the width (W) is calculated.
  • a cigarette paper is manufactured as in the above examples to produce a cigarette except that the grammage of the cigarette paper and the kind of calcium carbonate are changed as shown in the following Table 3.
  • the amount of visible sidestream smoke and the amount of carbon monoxide in the main stream smoke of the obtained cigarette are measured.
  • the results are indicated in Table 3.
  • the length (L) of the primary particle described in Table 3 is an average of the length (L) of 100 primary particles measured according to the above method.
  • the primary particles of bur-shaped calcium carbonate have an average aspect ratio of 6.7, and the primary particles of Cal-light-SA have an average aspect ratio of 9.5.
  • a cigarette paper is manufactured as in the above examples to produce a cigarette except that the grammage of the cigarette paper and the kind of calcium carbonate are changed as shown in the following Table 4.
  • the amount of visible sidestream smoke and the amount of carbon monoxide in the mainstream smoke of the obtained cigarette are measured.
  • the results are indicated in Table 4.
  • the primary particles have a needle shape
  • the average length (L) of the primary particles is 3.3 ⁇ m
  • the average aspect ratio of the primary particles is 8.0
  • the secondary particles have a bur shape.
