Abstract

The invention discloses a wadding wire composite filter stick for cigarettes and relates to a filter stick is compounded in the method that a wadding wire filter element and an acetate fiber filter element are wrapped in the same piece of outer ring forming paper. The wadding wire filter element made of a wadding wire material is prepared by taking paper for cigarettes as a raw material through embossing and cutting, the wrinkle depth of a wadding wire is 100 to 1000 microns, the thin wire of the wadding wire is 0.1 to 1.5 mm in width and 10 to 30 mm in length, and the density of the filter strip of the wadding wire is 1 to 3 g / cm<3>; the acetate fiber filter element or the wadding wire filter element can be individually wrapped with inner ring forming paper. The wadding wire composite filter stick can be prepared into a wadding wire composite filter tip, and the wadding wire filter element is assembled at a near cigarette tobacco end. According to the invention, the wadding wire is formed disorderly, a main stream smoke passage adopts a curvilinear style, the better filtering effect of the wadding wire composite filter stick is better than that of a conventional paper filter stick, quality control of resistance to suction and hardness are superior to that of other paper filter elements, and the application space of paper material filter sticks in the field of filter tips can be expanded.

Description

technical field

[0001] The invention relates to a composite filter stick with a paper core for cigarettes. Background technique

[0002] In the 1960s and 1970s, all cigarettes produced in the UK had a double filter, with a decorative paper at the end of the filter. By the late 1970s, most companies were producing their own acetate filters. With the advent of KDF2 - Manufacturer of Acetate Filters, the use of paper was greatly reduced. In conclusion, paper, semi-crepe paper to be precise, is less expensive, but has a better tar and nicotine removal ability than acetate. So why isn't it used anymore today? The reason paper is not accepted by consumers is that it has a "paper smell", which consumers often don't like. Therefore, paper filters have never been as popular as acetate filters, except for the aforementioned use of paper in duplex filters. The biggest negative effect is that the paper is soft and polluted seriously during smoking, so it is not suitable to be used...

Examples

Embodiment 1

[0034] use as figure 1 The crepe paper composite filter rod for cigarettes produced by the production process shown is made of crepe paper filter element 6 and the end face of acetate fiber filter element 5, which are spliced ​​together and wrapped in the same outer ring forming paper 2.

[0035] The crepe paper filter element 6 is made of cigarette paper (in the papermaking process of cigarette paper, wood pulp fiber is used as the main raw material, doped with a small amount of carbon fiber, and the doping ratio is 15-30%; it is also sprayed with granular additives). The cigarette paper is first crumpled, and the wrinkle depth formed by crumpling is 400~800μm; then cut into filaments with a width of 0.3-1.0mm and a length of 10-20mm, and then use a cigarette tipping machine to sort irregular filaments The roll is made into a fluffy degree or a density of 1.5g / cm 3 The crepe paper silk filter strip is finally cut into the designed length to form the crepe paper silk filter ...

Embodiment 2

[0037] like figure 2 The shown composite filter of crepe paper for cigarettes is made by cutting the composite filter rod of crepe paper for cigarettes in the above-mentioned embodiment 1, and then installed on cigarettes for use; the composite filter of crepe paper contains at least a section of vinegar A fiber filter element 5 and a section of crepe paper filter element 6; the crepe paper filter element 6 is individually wrapped with an inner ring forming paper 3, and the crepe paper filter element 6 is connected to the end 7 near the shredded tobacco.
