Capsule filter rod capable of reducing releasing amount of harmful substances in flue gas

Abstract

The invention provides a capsule filter rod capable of reducing releasing amount of harmful substances in flue gas. A cigarette filter rod comprises a cylindrical fiber filtering material, a fragile capsule arranged in the fiber filtering material and molding paper for covering the outer surface of the fiber filtering material. The prepared capsule is added into the cigarette filter rod; after the capsule is broken through a hand in a cigarette smoking process, the capsule filter rod has relatively good effect of reducing the releasing amount of the harmful substances in the flue gas and also has relatively good supplementing effect on aroma-inducing components in the flue gas; and the smoking taste of the cigarettes can be ensured and the smoking feeling of smokers is lifted.

Description

technical field [0001] The invention belongs to the technical field of cigarette filter rods. Background technique [0002] During the smoking process of cigarettes, the smoke produced by burning, pyrolysis and distillation is very complex. Thousands of compounds have been detected. Although the content of some compounds is very low, they are widely recognized in the field of smoking and health research. Widely concerned, Xie Jianping screened out the most representative 7 kinds of harmful components (CO, HCN, NNK, NH 3 , B[a]P, phenol and crotonaldehyde). In recent years, with the continuous improvement of people's living standards and quality of life, consumers have higher and higher requirements for smoking safety. Therefore, producing high-quality, low-tar, and low-harm cigarettes is an inevitable way for the development of the cigarette industry. [0003] The international cigarette industry has adopted a series of measures to reduce harm and coke, such as new techno...

Problems solved by technology

[0004] The materials used in the above studies are only considered from the perspective of reducing the hazards of cigarettes, without taking into account the difficulty of the production process, the impact on cigarette smoking style and cost factors in the actual application of the materials. In the case of light, there is instability, which increases the difficulty of using materials

Through the analysis of the existing filter rod technology, the existing harm reduction and coke reduction filter rod technology mainly focuses on granular composite filter rods, multi-element composite filter rods, grooved filter rods and other forms, while the simple capsule filter rod technology is used to There are few reports on the reduction of harmful substances in mainstream cigarette smoke
