Problems solved by technology

This technology improves the filtration performance of a single fiber microscopically, thereby improving the filtration performance of the filter rod. However, it does not take into account the different positions of the fibers in the filter rod and their different functions. Rods are less consistent and less selective for all flue gas components
[0006] Therefore, considering the performance of individual fibers at different positions in the filter rod and the interaction between fibers, maximizing the adsorption capacity of fibers to smoke and reducing the adsorption of aroma components is exactly the goal of the tobacco industry in developing cigarette filters. An important direction, but there is no report in the technology on this aspect

Embodiment 1

[0031] Three specifications of polypropylene fiber tows with monofilament linear densities of 2.0, 3.0, and 4.0 den were blended in proportions of 50%, 30%, and 20% respectively. The total density of the tows after blending was 25,000 den. The formed filter rod , the fiber distribution form is that the filter rod forms a linearly increasing distribution in the monofilament linear density along the axial center to the circumferential direction, and this tow filter rod is made into a cigarette filter rod according to the conventional filter rod forming process, and is applied to the cigarette Compared with the conventional polypropylene fiber filter rod cigarette with a tow specification of 2.7 / 25000, the cigarette can have a plump and harmonious aroma and reduce tar by 20%.

Embodiment 2

[0033] Seven specifications of polyacetate fiber tows with monofilament linear densities of 1.0, 2.0, 2.3, 3.3, 4.0, 5.0, and 6.0 den were respectively divided into 30%, 20%, 10%, 10%, 10%, 10%, and 10%. The ratio of blending is carried out. The total density of the tow after blending is 45000den. After forming the filter rod, the fiber distribution form is that the filter rod forms a linearly increasing distribution on the linear density of the single filament along the axial center to the circumferential direction. The bundle filter rod is made into a cigarette filter rod according to the conventional filter rod forming process, and is applied to the cigarette. Compared with the conventional cellulose acetate filter rod cigarette with the tow specification of 2.76 / 45000, it can make the aroma of the cigarette rich, elegant and mellow. The miscellaneous gas is light, the taste is comfortable, and the tar is reduced by 56%, and the moisture is increased by 25%.

Embodiment 3

[0035] Three specifications of polyacetate fiber tows with monofilament linear densities of 2.0, 3.0, and 4.0 den were blended at a ratio of 30%, 50%, and 20%, respectively. The total density of the tows after blending was 35,000 den. The formed filter rod , the fiber distribution form is that the filter rod forms a linearly decreasing distribution in the monofilament linear density along the axial center to the circumferential direction, and this tow filter rod is made into a cigarette filter rod according to a conventional filter rod forming process, and is applied to a cigarette Compared with conventional cellulose acetate filter plug cigarettes with a tow specification of 2.9 / 35000, it can make the aroma of the cigarette plump and mellow, reduce tar by 40% and increase moisture by 20%.

Abstract

The invention discloses a novel cigarette filter with mixed tows, which is prepared by respectively opening one or more of cellulose acetate fiber, polypropylene fiber, polyester fiber and regenerated cellulose fiber of different types of tows, blending in a ratio, and shaping to obtain cigarette filter with different density distributions and different material distributions from the axial core to the circumference, wherein the smoke filtering performance of each fiber is different from others. While filtering smoke, the cigarette filter can greatly improve the smoke filtering efficiency through the combination of tows with different density distributions and different materials, thus facilitating retention of flavor component, fully exerting the maximal effect of each fiber, and flexibly adjusting between accurate control and selective adjusting of smoke components according to the design and the application requirement for cigarette.

Description

technical field [0001] The invention belongs to the technical field of cigarette materials, and in particular relates to a novel tow mixed and matched filter rod used in cigarettes. Background technique [0002] As a bridge between smokers and mainstream smoke, cigarette filters can effectively filter out some harmful components in smoke, so they have been widely valued and applied. Cigarette tipping filter can improve smoking safety, alleviate the contradiction between smoking and health, and reduce the degree of health damage caused by smoke inhalation. A large number of research results have shown that using different filter tips to attach to cigarettes can reduce cigarette tar by 20% to 50%. Therefore, the tobacco industry in various countries in the world has used the latest technology to continuously develop more effective cigarette filters to meet the special needs of the cigarette industry. [0003] Cigarette filters are divided into ordinary filters, compound filt...
