Problems solved by technology

In addition, due to its structural characteristics, the cellulose acetate fiber cannot smoothly suppress the volatilization of the fragrance liquid that penetrates into the pores. In this case, most of the fragrance liquid is discharged in the initial stage of smoking. Expressiveness can be drastically reduced
In addition, when an excessive amount of perfume is added to the cellulose acetate fiber, the physical properties of the filter (such as suction resistance, girth, etc.) may also change due to the swelling phenomenon
[0005] On the other hand, the filter plug or wrapper around the smoking substance may become wet and contaminated if in any way more than the acceptable limit of flavoring is added

Embodiment 1

[0086] A filter rod having a circumference of 23.8 mm and a length of 96 mm was prepared according to the conditions set forth in Table 1 below. As the wrapping paper of the filter stick, a wrapping paper with a basis weight of 21 gsm was used, and the ratio (%) in the core rod was the ratio of the area of ​​the filter substance to the total area of ​​the filter core rod, which was related to the content of the filter substance. In addition, as a filter material, a bulk thickness of 2.40 cm was used 3 / g of paper.

[0093] Experimental Example 1: Comparison of Maximum Capacity (Additional Amount) of Fragrance Liquid

[0094] With respect to the filter rods of Example 1 and Comparative Example 1, an experiment to measure the maximum holding amount of fragrance liquid (for example, the maximum addition amount per unit mm) was conducted. The maximum holding capacity of the fragrance liquid is measured on the basis of whether the wrapping paper of the filter stick is wet or not, and whether the wrapping paper is wet or not is determined by visual inspection. The results of this experimental example are shown in Table 3 below.

Embodiment 2 to 8

[0099] Filter rods were prepared according to the conditions described in Table 4 below. Other conditions (eg, bulk, plug circumference, length, etc.) were the same as in Example 1. In addition, in the case of Examples 2 to 4, PG was used as the solvent of the fragrance liquid, and in the case of Examples 5 to 8, MCTG was used as the solvent of the fragrance liquid.

Abstract

A filter for a smoking article and a smoking article including the same are provided. A filter according to some embodiments of the present disclosure may comprise: a filter core rod containing a filter material; and the liquid substance is added into the filter core rod. At this time, the molecular weight of the hydrophilic group of the filtration substance may be greater than or equal to the molecular weight of the hydrophobic group, and in this case, a change in filtration performance due to the addition of the liquid substance may be minimized.

Description

technical field [0001] The present disclosure relates to a filter for a smoking article and a smoking article including the filter. Background technique [0002] Smoking articles (eg, cigarettes) are flavored in various ways to suit smoker preferences. As an example of a representative flavoring treatment, a method of directly adding (eg, spraying) a flavoring liquid to a smoking substance or a filter rod constituting a smoking article can be cited. However, the cited methods have problems that the amount of the fragrance liquid added is limited, the desired fragrance cannot be expressed, or the fragrance expression performance is drastically reduced during smoking. [0003] Specifically, according to the method of adding the fragrance liquid to the smoking substance, since the fragrance liquid and the smoking substance may aggregate with each other, it is difficult to add a large amount of the fragrance liquid. In addition, the fragrance liquid may deteriorate due to the ...
