The invention relates to a wooden fiber paper adhesive-applied filter rod for cigarettes and a preparation method thereof. The method comprises the following steps of: adopting wooden fiber paper as a filtration material; applying an adhesive in the forming process of the filter rod; conveying through a stable roller; rotating, cutting and rolling; evenly spraying the adhesive on a paper tape in a centrifugal spraying mode; and conveying to a filter rod forming machine through a conveying roller to form the filter rod. The product solves the performance problems of poor taste permeation, unconspicuous coke-reducing effect, and the like of polypropylene filter rods, castoffs are easy to degrade and environment-friendly and sanitary, and the filter rods for the cigarettes are easy to cut with smooth incisions and good hardness, resist appearance deformation and can be applied to medium-high-grade cigarettes instead of cellulose acetate filter materials.
