Composite filter rod supportive of heat exchange

Abstract

The invention provides a composite filter rod supportive of heat exchange. The composite filter rod comprises a heat-exchange-supportive fixing member section and an acetic fiber section, the heat-exchange-supportive fixing member section accounts for 10-60% of the whole composite filter rod in length and comprises a capillary pipeline and a smoke passage, and a volume ratio of the capillary pipeline and the smoke passage is 1:3-20:1. The composite filter rod can play a role in lowering smoke temperature of cigarettes, and satisfaction of consumers and cigarette smoking quality are improved.

Description

technical field [0001] The invention belongs to the technical field of cigarette filter rod preparation, and in particular relates to a heat-exchangeable filter rod capable of effectively reducing the temperature of cigarette smoke. Background technique [0002] The tow in the cigarette filter rod is mostly made of cellulose acetate tow material. The main function of the filter rod is to filter the cigarette smoke, and has a small cooling effect on the smoke. After the shredded tobacco of ordinary cigarettes is burned, the temperature of the smoke tends to increase gradually with the increase of the number of puffs. After the flue gas passes through the filter, the temperature of the flue gas is higher in the later stage, especially in the case of continuous smoking. During the first few puffs of suction, the temperature of the flue gas in the middle of the filter rod is generally around 40°C. In the case of continuous suction, the temperature of the subsequent flue gas can...

Problems solved by technology

Therefore, in the case of continuous suction, as the temperature of the mainstream smoke in the filter rod rises, the condensation effect of the condensable particulate matter will be weakened to a certain extent, and macromolecules will not be formed by combining, and the impact of the filter rod tow on the mainstream smoke will be weakened. Filtration of mesoparticles

[0004] Therefore, the sensory quality of cigarettes has a certain relationship with the temperature of cigarette smoke. Cigarette smoke within a certain temperature range can enhance consumers' sense of satisfaction, moisturization, and richness of aroma; when the temperature of cigarette smoke is high, consumers There will be irritating sensations such as dryness and burning sensation, which will reduce the satisfaction of consumers and the quality of cigarette smoking
