Composite cigarette filter tip capable of improving mouthfeel of novel cigarette and application thereof

The invention relates to the technical field of tobacco manufacturing, in particular to a composite cigarette filter tip capable of improving mouthfeel of a novel cigarette and an application thereof.The composite cigarette filter tip capable of improving mouthfeel of the novel cigarette is obtained by composition of at least one solid section and at least one cigarette tow section. One or multiple hole channels are arranged in the solid section. As for a novel cigarette product, a tobacco section does not burn and generates smoke by depending on heat sources and other effects. The heating temperature is far lower than the burning temperature of a conventional cigarette. Hole channels arranged in the solid section help minimize the obstruction and interception effects of the filter tip upon smoke, reduce the loss of smoke in the filter tip and improve smoke concentration. Additionally, the hole channels in the solid section are filled with fragrant particles or coated with fragrant layers. When a user smokes the novel cigarette, the cigarette filter tip draws close to the tobacco section so that temperature goes high. Therefore, fragrant components are released at high temperatureto increase aroma concentration and enrich smoke. As a result, the mouthfeel of the novel cigarette is effectively improved.
