Problems solved by technology

[0004] However, since the above-mentioned low-burning cigarettes in the past are produced by introducing the paper coated with the combustion control area into the cigarette making machine, wrapping the tobacco filling material with the paper, and cutting the resulting long columns into cigarettes Therefore, it is difficult to keep the pattern of the combustion control zone on each cigarette preset in advance and the style of the combustion control zone on each cigarette actually manufactured by cutting off the columnar body
Not only that, but coating the combustion control area in the manufacture of the roll paper will result in high manufacturing costs

Embodiment 1

[0120] First, coating materials containing various combustion modifiers were prepared by the following procedure.

[0121] (1) Dissolve commercially available potato starch in water at a concentration of about 25% by weight, then heat to prepare a starch paste (coating material A)

[0122] (2) Carboxymethylcellulose (CMC) powder sold on the market is dissolved in water at a concentration of about 5.2% by weight to prepare a CMC paste (coating material B)

[0123] (3) CMC powder and ammonium dihydrogen phosphate sold on the market are dissolved in water at a concentration of about 5.2% by weight and about 2.5% by weight respectively (coating material C)

[0124] (4) Use commercially available sodium polymethacrylate with a polymerization degree of 2700-7500 as a coating material (coating material D)

[0125] In making the weight 22.6g / m 3 Tobacco paper (tobacco paper A) with an intrinsic air permeability of 10CU, with a weight of 25.6g / m 3 Tobacco paper with an intrinsic air...

Embodiment 2

[0128] In this embodiment, cigarettes are produced by changing the width and interval of the stripe-shaped combustion control regions.

[0129] That is, using a CMC aqueous solution with a concentration of 4% by weight, as shown in Table 2 below, a strip-shaped combustion control area is formed on each roll paper by the method of screen printing. Using this roll paper, the same as in Example 1, for each Each sample produced 6 cigarettes. For each cigarette, the natural burning rate and the ignitability to cloth were measured in the same manner as in Example 1. The results are listed together in Table 2.

Embodiment 3

[0131] Tobacco paper C is used as the tobacco paper used, and it is determined by CMC at 3.1g / m 2 The ratio is applied to form a streaked burn control area. The width of the combustion control area is a specified value of 2.5 mm, the interval is a specified value of 2.5 mm, the number of combustion control areas is a specified value of 5, and the content of puffed shredded tobacco in the tobacco filling material is changed. Like Example 1, for each sample Both make 6 sticks of cigarettes. For each cigarette, the natural burning rate and the ignitability to the cloth (cotton canvas No. 6) were measured in the same manner as in Example 1. The results are listed together in Table 3.

Abstract

A smoking article is manufactured through supplying a tobacco filler material onto a tobacco wrapping paper sheet that is transferred, wrapping the tobacco filler material supplied onto the tobacco wrapping paper sheet with the tobacco wrapping paper sheet so as to prepare a rod body, and cutting the rod body into a plurality of tobacco rods each having a prescribed length. The tobacco filler material contains at least 20% by weight of expanded tobacco material. The tobacco wrapping paper sheet is coated with the burn adjusting agent during transfer of the tobacco wrapping paper sheet.

Description

technical field [0001] The present invention relates to a low-flammability tobacco product which keeps burning under normal smoking state but does not spread the combustibles on the combustibles and its manufacturing method. Background technique [0002] In recent years, various requirements have been imposed on tobacco products such as cigarettes. One of them is to reduce the amount of sidestream smoke. Recently, tobacco products have been proposed to continue to burn under the usual smoking state, but they can be extinguished on the combustibles, so that the combustibles are not allowed to burn. [0003] Japanese Unexamined Patent Publication No. 11-151082 discloses the following low-burn-prolongation cigarette. Inorganic fillers such as chalk, clay, and titanium oxide are suspended in a solvent-soluble cellulose polymer dissolved in a non-aqueous solvent, and the resulting suspension is applied in a ring shape on a cigarette column wrapper. On the rolling paper, in thi...
