example 1

[0052] Using the paper shown in Table 1 above as a filter wrap, a filter plug was manufactured by a conventional method. The filter material used was conventional cellulose acetate tow to which triacetin was added in an amount corresponding to 6% by weight of the weight of the cellulose acetate tow. As far as the diameter of the filter rod is concerned, its circumference is 24.5 mm and its length is 25 mm. The rolled paper properly covers the outer periphery of the filter material. And the hardness of the obtained filter was measured.

[0053] Originally, the hardness of the filter should be measured with the filter attached to the cigarette. However, it is difficult to measure the hardness of the filter when the filter is attached to the cigarette due to the problem of the measuring device. Therefore, the filter hardness was measured in the state of the filter rod before the filter was attached to the cigarette (hereinafter, the same measurement method was used for the fil...

example 2

[0058] Filter rods of the same size as those in Example 1 were manufactured using the regular rolled paper P and the high stiffness and high air permeability paper S4 shown in Table 1, respectively. Filter material is the same as example 1, what adopt is conventional cellulose acetate fiber tow, but has changed the addition amount of triacetin relative to tow (corresponding to 0~ of cellulose acetate fiber weight). 12% by weight). The hardness of the obtained filter rod was measured in the same manner as in Example 1. The result is as Figure 5 shown. exist Figure 5 Among them, line a represents the result when roll paper P is used; line b represents the result when high stiffness and high air permeability paper S4 is used.

[0059] Depend on Figure 5 It can be seen that, at any amount of triacetin added, compared with the filter plug using conventional wrapping paper P, the use of high stiffness and high air permeability paper S4 achieves an increase in filter tip hard...

example 3

[0063] Using the papers shown in Table 1, so-called paper plugs were produced. As a filter material, creped pulp paper was used. The resulting filter rod had the same shape as in Example 1. The ventilation resistance (ventilation resistance) of each filter rod is 350mmH 2 O / 120mm. The hardness of the obtained filter rod was measured in the same manner as in Example 1. The result is as Figure 6 shown.

[0064] Depend on Figure 6 It can be seen that, the same as the case of the cellulose acetate filter rod wrapped by the high rigidity and high air permeability paper of the present invention shown in Example 1, the paper filter rod of the high rigidity and high air permeability paper of the present invention is used. The hardness has been fully improved. Furthermore, by adopting the present invention, the hardness of the cellulose acetate filter can be increased to a level equivalent to the hardness of the filter when 6% by weight of triacetin is added.

Abstract

Disclosed is a cigarette provided with a single-segment filter and a multiple-segment filter. The single-segment filter has a single filter plug, and employs the highly rigid and permeable paper which has a vertical rigidly of 30 or more, as measured by JIS P8143, and a Coresta permeability of 1,000 or more, as the roll paper for rolling a filter material. The multiple-segment filter has a plurality of filter plugs, and employs the highly rigid and highly permeable paper, as the roll paper for rolling the filter material and / or the shaping paper for connecting a plurality of filter plugs.

Description

technical field [0001] The invention relates to a cigarette filter tip and a cigarette with the filter tip. Background technique [0002] In order to alleviate, for example, the taste of smoke (taste), cigarettes with filters have been developed and put on the market. A filter-tipped cigarette is a cigarette provided with a filter at one end of a cigarette body containing a cigarette filler rod such as shredded tobacco, and the outer periphery of the cigarette filler rod is wrapped with paper. The filter has at least one filter plug. Each filter plug contains a filter material in a cylindrical body made of paper (filter plug wrapper) wound into a cylindrical shape (usually a cylindrical shape). The filter is provided at one end of the cigarette main body through a tip paper. [0003] For smokers, the filter hardness of cigarettes with filters is one of the indicators for choosing cigarettes. Most currently commercially available filter cigarettes use cellulose acetate fi...
