The utility model relates to a cigarette production field especially relates to an inner groove ternary composite filter rod for cigarette. An inner groove ternary composite filter rod for cigarette, this filter rod of uses filter core to be the nuclear core, and filter core outside parcel has the one deck filter rod paper that takes shape, the filter core by acetate section, paper strain rod segment and acetate slot section three -section in proper order alternate joint constitute, the acetate section for the nearly lip section of filter rod after cutting, rod segment is strained by the high rigidity to the paper, and the filter rod one -tenth made of paper that takes shape is wrapped up in to paper bag that the porosity is high, acetate slot section comprises on two -layer parcel layer inside and outside with two acetate silk bundles, and interior parcel layer is slot pure cellulose paper to evenly the suppression has the axial slot on the outer periphery of cellulose paper, and outer parcel layer is the shaping paper of filter rod. The utility model discloses the burnt effect of falling of filter rod has been improved. Compare with ordinary filter rod, its range of decrease to cigarette mainstream smoke can reach 10% - 30%, has increased and has absorbed the security.
