Abstract
The invention discloses a binary composite drainage cigarette filter stick which comprises a silk flock filter element and a piece of packaging paper coating the silk flock filter element. The silk flock filter element is formed by a first section filter element and a second section filter element in the direction from a smoke inlet to a smoke outlet. A plurality of drainage grooves are further formed in the surface of the periphery of the second section filter element. The drainage grooves are communicated with the outer end face of the second section filter element. The pressure drop of the second section filter element is more than 200Pa/cm. When the binary composite drainage cigarette filter stick is applied to cigarette smoking, when smoke stays in the first section filter element, due to the fact that smoking resistance in the center of the second section filter element is quite large, the smoke in the center of the first section filter element is forced to gradually turn to the periphery of the first section filter element, and when the smoke reaches the second section filter element, due to the facts that the smoking resistance in the middle is quite large and the drainage grooves are formed in the periphery so as to be small in smoking resistance, the smoke does not essentially pass through the second section filter element through the center and directly passes through the second section filter element through the peripheral drainage grooves. Therefore, on one hand, the filter effect of silk flocks on the periphery of the first section filter element is improved, and on the other hand, adjustment of the color and luster of a filter tip after a person smokes a cigarette is achieved.
