The invention provides a process for producing a composite filter rod of tea dust, mainly comprising two working procedures, i.e., making corrugated paper with reticular grooves and making the composite filter rod with shaping paper and a tow in seamless bonding, wherein the working procedure of making corrugated paper with reticular grooves mainly comprises the steps of making corrugated paper coating, drying, pressing the corrugated paper, slitting the corrugated paper and rolling narrow corrugated paper; and the working procedure of making the composite filter rod with the wrapping paper and the tow in seamless bonding comprises the steps of spraying the tea dust, wrapping the corrugated paper, wrapping the shaping paper and slitting the finished product. By means of the technical scheme, the shape of the corrugated paper with grooves is relatively fixed and the corrugated grooves do not deform so that the air permeability of a filter tip rod is increased and the processing and using requirements of the filter tip rod are satisfied; the corrugated paper is bonded with the tow so that the clearance on the contact surface can be eliminated and the permeated air can penetrate intothe inner layer of the tow; and tealeaf powder is added in the filter tip rod so that harmful components in the smoke can be adsorbed and the content of the harmful components in the smoke can be reduced.
