Tobacco fiber filter stick, preparation method, and composite filter tip of tobacco fiber filter stick

Abstract

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.

Description
