Description

Preparation method of dust-free paper with cooling function and its application to composite filter rod

technical field

The invention belongs to the field of cigarette materials, relates to modified dust-free paper, in particular to a preparation method of dust-free paper with cooling function and its application to a composite filter rod.

Background technique

With the development of cigarette production technology, short cigarettes and heat-not-burn tobacco products are more and more favored by consumers. Compared with traditional cigarettes, short cigarettes have shorter cut tobacco lengths. In order to ensure the number of puffs, the length of the filter tip is also shortened accordingly. Traditional cigarettes use longer cut tobacco sections and filter sections to cool down, while the lengths of the cut tobacco sections and filter sections of short cigarettes are shortened, resulting in poor cooling effect, and the temperature of smoke entering the oral cavity is too high, causing smoking Sometimes there is a burning sensation.

Although the smoke temperature of heat-not-burn tobacco products is much lower than that of traditional cigarettes, due to the special structure of the filter section, and the cartridges are completely placed in the heater, physical cooling cannot be carried out, and when the smoke enters the oral cavity, the The temperature is also high, and there is a burning sensation in the mouth.

The dust-free paper with the cooling function and the composite filter rod thereof disclosed in the invention can rapidly reduce the temperature of the flue gas without affecting the quality of the flue gas.
