The utility model provides a fiber paper material with embossed broken line patterns for a filter rod. Embossed patterns on base paper of the prior filter rod generally adopt a straight line pattern manner; and when the base paper with the straight line patterns is adopted to manufacture the filter rod, as smoke can rapidly flow along the straight line patterns, the filtering efficiency of filament tows is greatly reduced. The fiber paper material is characterized in that straight-line-shaped or S-shaped embossed broken line patterns, which are mutually parallel in the transverse direction and distributed at intervals in the longitudinal direction, are embossed on a fiber base paper layer of the filter rod, wherein the distance between every two transverse rows of the embossed broken line patterns is 0.8 to 1.2mm; and every two longitudinal rows of the embossed broken line patterns are evenly distributed at intervals, and the distance is 1 to 2mm. After the embossed broken line patterns are embossed on the base paper of the paper filter rod of a cigarette, the base paper is provided with a concave-convex structure, so that flow resistance to the smoke is increased, the interception efficiency and the filtering effect over the smoke are improved, and the release amount of harmful substances and the harm of the harmful substances to a human body are reduced to the maximum degree. The filter rod produced by using the base paper has a steady quality characteristic, and the filtering efficiency of the filter rod produced by using the base paper is increased by 15 percent than a traditional filter rod with longitudinal-transverse embossed patterns.
