Activated carbon composite filter stick and preparation method thereof

The invention relates to the technical field of cigarette filter sticks, in particular to an activated carbon composite filter stick and a preparation method thereof. The activated carbon composite filter stick comprises a modified adsorption section formed by rolling a modified non-woven fabric, one of two opposite surfaces of the modified non-woven fabric is provided with activated carbon, and the other surface of the modified non-woven fabric is provided with a base material essence. The activated carbon and the base material essence are respectively coated on two opposite surfaces of the non-woven fabric, so that the blocking of the base material essence on the activated carbon through holes is effectively avoided, the modified non-woven fabric with strong adsorbability and faint fragrance is obtained, and the modified adsorption section prepared from the modified non-woven fabric is applied to the cigarette filter tip, so that the cigarette filter tip has the advantages that the cigarette filter tip is n
