Filter stick with dredging grooves
Disclosed is a filter stick with dredging grooves. Tows of the filter stick are wrapped inside molding paper, and tow dredging grooves with low tow filling densities are processed in the tows in the molding paper and communicate front and rear ends of the filter stick along an axial direction.

| description | Disclosed is a filter stick with dredging grooves. Tows of the filter stick are wrapped inside molding paper, and tow dredging grooves with low tow filling densities are processed in the tows in the molding paper and communicate front and rear ends of the filter stick along an axial direction. The number of the tow dredging grooves is in a range from two to ten, and the tow dredging grooves are evenly distributed on the periphery of the filter stick. As the technical scheme is used, the amount of dilution airflow entering the filter stick can be increased apparently, the increased dilution airflow reduces the smoke density; due to the effect of a negative pressure zone in the filter stick, the smoke flows transversely, and the tar filtering efficiency is improved; and according to the technical scheme, the tar ingredient in the smoke can be decreased, and the density can be effectively reduced under the condition that the cigarette smoking smell is basically not changed. |
