Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of cigarette materials and relates to a filter rod, in particular to a porous and colorful composite filter rod. Background Art
[0002] The filter rod is made of cellulose acetate tow or polypropylene fiber tow for cigarettes, and its end surface usually has only one color, that is, white, and has no visual identification characteristics. At present, there are also some special filter rods that use empty tubes or grooves, which improve the visual characteristics of the filter rods to a certain extent, but they are highly homogeneous, easy to be imitated, and have weak characteristics.
[0003] Patent CN201238601Y discloses a color pattern cigarette filter rod with anti-counterfeiting function, which discloses a filter rod with a color pattern on the end face, that is, different colored tows are made into long strips of a certain shape and spliced together, but its preparation method is complicated, the splicing of filter strips of different shapes is difficult, and the production efficiency is low. Summary of the invention
[0004] The utility model aims to disclose a porous and colorful composite filter rod.
[0005] Technical Solution
[0006] A porous colorful composite filter rod comprises a cylindrical shaping paper, wherein the shaping paper is provided with two sections of porous hollow tube filter rods and colorful filter rods connected end to end, wherein the colorful filter rod is composed of no less than two strands of dyed filament bundle filter strips arranged in parallel, and the colors of two adjacent strands of dyed filament bundle filter strips are different, the number of holes in the porous hollow tube filter rod is consistent with the number of colors of the dyed filament bundle filter strips of the colorful filter rod, and different colors can be observed through different holes.
[0007] The plugging paper is oil-proof plugging paper or high-transparency plugging paper, preferably oil-proof plugging paper.
[0008] The pore diameter of the porous empty tube filter rod is between 1.0 and 3.0 mm.
[0009] The dyed yarn bundles include but are not limited to cellulose acetate yarn bundles, polypropylene fiber yarn bundles, polylactic acid yarn bundles, polylactic acid-PET composite yarn bundles, and ES fiber yarn bundles; preferably cellulose acetate yarn bundles or polypropylene fiber yarn bundles.
[0010] Beneficial Effects
[0011] The porous colorful composite filter rod disclosed by the utility model has two different colored bundles on the end surface to naturally form a color transition zone, has a stronger anti-counterfeiting ability and a more significant appearance characteristic, and improves the appearance characteristics and anti-counterfeiting ability of the filter rod.
