The invention provides a tobacco
fiber filter stick and a preparation method thereof. The tobacco
fiber filter stick is prepared by wrapping forming paper outside a
paper filter element which contains tobacco
plant fibers, wood pulp fibers, and
modified cellulose fibers and used as a
filter material of the filter stick. The
filter element contains the following components in percentage by weight: 2 to 10 percent of tobacco
plant fiber, 10 to 80 percent of wood pulp fiber, 5 to 45 percent of
modified cellulose fiber, and 0 to 80 percent of other components, and the sum of the weight percentage of all the components is 100 percent. The method comprises the following steps of: mixing the tobacco
plant fibers, the wood pulp fibers, the
modified cellulose fibers,
papermaking auxiliary materials, and water to obtain
slurry, preparing the tobacco fiber paper by using the
slurry, preparing the
filter element of the tobacco fiber paper by using the tobacco fiber paper, and finally preparing the tobacco fiber filter stick by using the
filter element of the tobacco fiber paper. The tobacco fiber filter stick can also be prepared into a
composite filter tip. The filter stick has the taste of tobacco, the tobacco plant fibers are not burnt in the filter element, and the generation and
discharge of toxic and harmful gas can be avoided; and the tobacco fiber filter stick has the natural color of the natural tobacco, and is easily distinguished from a common white filter stick.
