Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a novel tobacco smoke body, and more particularly, to a tobacco smoke body in which powdered cellulose acetate is bound using a plasticizer. Things.

[Prior art and its problems] As a conventional body for cigarette smoke, there is mainly cellulose acetate fiber. Cellulose acetate fiber is said to have a good balance of smoke components in cigarette smoke and to have good taste. Cellulose acetate fiber is produced by dissolving cellulose acetate flakes in acetone and extruding the fiber from a die. The extruded fibers are bundled into a bundle to form a tow. The tow is plugged on a hoist to form a rod-like body.

As described above, the spinning / winding and manufacturing process for manufacturing the superficial body are long, and the manufacturing cost is high.

[Means for Solving the Problems] As a result of repeated studies for the purpose of simplifying the process and manufacturing inexpensively a tobacco having a cellulose acetate fiber bulk and a bulk having the same taste, the present inventors have found that powder The excess (hereinafter referred to as the excess) in which a plasticizer is adhered to and bound to cellulose acetate in a state (hereinafter referred to as the excess) has been found to sufficiently satisfies the object, and has led to the present invention.

That is, the present invention provides: 1) a tobacco smoke body obtained by binding powdered cellulose acetate; 2) a plasticizer adhered to powdered cellulose acetate;
An object of the present invention is to provide a method for producing a tobacco smoke body, which comprises binding the powdered cellulose acetate.

The cellulose acetate used in the present invention is obtained by esterifying cellulose with acetic anhydride, and generally has a degree of polymerization of 100 to 500, and a degree of acetylation of 40 to 62.5%. Those can also be suitably used. The flakes of cellulose acetate produced from cellulose are pulverized and classified, if necessary, to obtain powdered cellulose acetate. The particle size of the powdered cellulose acetate has an average particle size in the range of about 0.3 to 5 mm, and the ease of inhalation of a person when the excess body is connected to tobacco,
It is appropriate to judge from the removal rate of the smoke component.

The plasticizer used in the present invention can be any plasticizer that dissolves cellulose acetate. For example, triacetin (glycerol triacetate), triethylene glycol diacetate, diethylene glycol diacetate, diethylene glycol monomethyl ether, triethylene glycol monomethyl ether , Diethylene glycol dimethyl ether, triethylene glycol dimethyl ether, dimethyl phthalate and the like are preferably used.

The method for adhering the plasticizer in the present invention may be carried out by wiping a mist-like plasticizer into powdered cellulose acetate, or by mixing the plasticizer and powdered cellulose acetate with a known blender. The amount of plasticizer attached is the granular cellulose acetate
It is used in the range of 4 to 50 parts by weight based on 100 parts by weight. If the amount of the plasticizer adhering to the powdered cellulose acetate is less than 4 parts by weight, the bonding between the powdered cellulose acetates is poor, and when the excess is connected to tobacco and smoking is performed, the cellulose acetate powder is applied to the human mouth. If the product falls into the market and the commercial value is reduced, or if the excess is cut to a predetermined length in the manufacturing process, the cellulose acetate powder falls off. When the adhesion amount of the plasticizer exceeds 50 parts by weight, the binding between the powdery cellulose acetates is improved,
The hardness of the excess body becomes too soft, and when the excess body is connected to tobacco and smoked, the tobacco smoke contains a large amount of plasticizer, and the taste becomes poor.

The molding method of the present invention can be produced by attaching a plasticizer to powdered cellulose acetate, placing the plasticizer in a molding die, and allowing it to stand at room temperature. The molding temperature is preferably from room temperature to about 100 ° C. The molding time varies depending on the temperature, but is preferably from 5 minutes to 30 hours.

The molding die may be a mold having the size of a cigarette smoke body, a long cylinder, or a flat plate. As a component of the mold, any material that does not dissolve in a plasticizer, such as metal, glass, paper, and plastic, can be used.

[Examples] In each example, the method of preparing a tobacco smoke body and performing a performance test was performed as follows.

Cellulose acetate (average degree of polymerization 180, degree of acetylation 54.6
%) The powder obtained by passing through a sieve had a particle size of 0.5 to 3.5 mm. The plasticizer was applied to the cellulose acetate powder with a fogger.

This plasticizer-adhered cellulose acetate powder is wrapped around 24.7
It was put in a paper cylinder of mm and left for 1 day. Length of this molded body
It was cut into 17 mm pieces to make the body, and it was joined to the tobacco part obtained by removing the body from cherry (manufactured by Japan Tobacco Inc.). This over-connected cigarette is used with a constant flow rate type smoker. Standard conditions: flow rate 17.5 ml / sec, smoking time 2 sec / time, smoking frequency 1 time / min, smoking length: 50 mm. After smoking completion, the amount of tar and nicotine attached to an over the body (respectively T _T and T _N) and tar and the amount of nicotine deposited on the Cambridge filter of a smoking device smoke components collecting for (each C _T and C _N) It was measured and the removal rate of each substance was determined using the following equation.

The airflow resistance is a value obtained by expressing the airflow resistance when 17.5 ml of air per second is passed only through the body by using a water column. The flavor was evaluated by a sensory test panel of five persons whose test pieces were bonded to the cherry by the above-mentioned method. The evaluation was divided into three classes and indicated by the symbols on the right.

No change from conventional product ○ slightly different from conventional product △ different from conventional product × Example 1 Triacetylene as a plasticizer was applied to powdered cellulose acetate by spraying at a weight ratio of 100: 15, respectively, by spraying. Filled into paper cylinders. After standing at room temperature for one day, the molded body was cut to obtain a cigarette smoke body having a circumference of 24.7, a length of 17 mm, a weight of 0.24 g, and a ventilation resistance of 57 mm. The body was connected to a cherry, allowed to smoke, and the rate of tar and nicotine removal was measured. A sensory test was also performed. The results are shown in Table 1. As shown in the table, it is clear that the superficial substance has the same performance as that of the comparative product.

Comparative Example 1 A body for tobacco smoke was obtained using cellulose acetate tow. A filament denier of 4 deniers and a total denier of 40,000 tows and a triacetin as a plasticizer were used to wind up a 102 mm body. Cut this to 17mm,
A body with a circumference of 24.7 mm, a length of 17 mm, a weight of 0.16 g and a ventilation resistance of 57 mm was obtained. Table 1 shows the results of evaluation of this excess by the same method as in Example 1.

Example 2 Powdered cellulose acetate was sprayed with diethylene glycol diacetate as a plasticizer at a weight ratio of 100: 20, and filled in a paper cylinder to be molded. After leaving at room temperature for one day, cut the molded
A body having a thickness of 17 mm, a length of 1.80 g and a ventilation resistance of 36 mm was obtained.
The excess was subjected to the measurement of the removal rate of tar and nicotine and the sensory test in the same manner as in Example 1. The results are shown in Table 2. As shown in Table 2, this super body had performance comparable to that of the comparative product.

Comparative Example 2 A body for cigarette smoke was obtained using cellulose acetate tow. Using a tow of filament denier 5.5 denier and total denier 31000 as a plasticizer, triacetin was used to wind up a body of 102 mm. This was cut into 17 mm to obtain a cigarette smoke body having a circumference of 24.7 mm, a length of 17 mm, a weight of 0.14 g, and a ventilation resistance of 37 mm. This excess was evaluated in the same manner as in Example 1, and the results shown in Table 2 were obtained.

[Effects of the Invention] The present invention simplifies the production process and provides a body having the same effect as the body for tobacco smoke made of cellulose acetate tow.
