Description

Technical Field

[0001] The invention belongs to the technical field of tobacco filter rods, and in particular relates to a filter rod with tar reduction, harm reduction and degradation functions. Background Art

[0002] As an important component of the "three papers and one stick" in cigarettes, filter rods have a significant impact on the smoking quality, tar reduction and harm reduction of cigarettes. At present, the commonly used filter rods on the market generally use acetate fiber tow as the main filter material. It has good elasticity and thermal stability, and can effectively intercept harmful components such as tar and nicotine in the smoke. It is an excellent filter material for cigarettes. However, the wood pulp raw material for the production of acetate fiber tow mainly relies on imports, and the production cost is relatively high, and there is a huge room for substitution. In addition, the biodegradation time of acetate fiber tow is long, resulting in the main treatment methods of discarded filter rods being incineration and landfill, which causes great environmental pollution.

[0003] In order to achieve the functions of tar reduction, harm reduction and degradation, paper filter rods have been studied at home and abroad. Paper filter rods are made of sheets made of natural plant fibers and rolled by wrinkles. They have strong biodegradability and low raw material costs, which are more in line with the industry's "saving, clean, and green" development concept. At the same time, paper filter rods have more significant filtering performance for harmful substances such as tar in flue gas, giving them greater advantages in the field of tar reduction and harm reduction. However, due to its high interception rate of various components in flue gas, it also brings problems such as lighter smoke, insufficient aroma, and heavier paper smell. Summary of the invention

[0004] The object of the present invention is to provide a filter rod with tar reduction, harm reduction and degradation functions to solve the problems existing in the above-mentioned background technology.

[0005] To achieve the above objectives, this application is implemented through the following technical solutions:

[0006] A filter rod with tar reduction, harm reduction and degradation functions, which is a single element composed of functional bars or includes multiple elements assembled in the form of bars. If it is assembled from multiple elements, at least one element is a functional bar;

[0007] The functional bar is a bar with tar reduction, harm reduction and degradation functions. After the cigarette smoke passes through the functional bar, tar and nicotine can be adsorbed by 0-80%.

[0008] Furthermore, the functional rod comprises a plurality of longitudinally extending channels and has a porosity between 30% and 90% in the longitudinal direction and a total area of ​​100 to 1000 mm2 per millimeter of axial length.

[0009] Furthermore, when the porosity is between 38% and 80%, the total area is 200-700 mm2 per millimeter of axial length.

[0010] Furthermore, the circumference of the functional rod is between 15-28 mm, and the axial length is between 5-40 mm.

[0011] Furthermore, the functional rod is prepared from a sheet material comprising degradable fibers.

[0012] Furthermore, pits are evenly arranged on both sides of the sheet.

[0013] Furthermore, the degradable fibers include but are not limited to one or more of lyocell fibers, polylactic acid fibers, viscose fibers, bamboo pulp fibers, cotton pulp fibers, mahjong fibers, and wood pulp fibers.

[0014] Furthermore, the sheet material is nonwoven fabric.

[0015] Furthermore, the nonwoven fabric has a basis weight of 20-100 g / m2, a breaking strength of 5-100 N, and a thickness of 100 um-1000 um.

[0016] Furthermore, if it is assembled from a plurality of components, the other components are one or more of an acetate fiber filter rod, a polylactic acid fiber filter rod, a paper filter rod, a reconstituted tobacco filter rod, an injection molded filter rod, a paper tube, and the like.

[0022] The technical solution of the present invention is described in detail below. The following embodiments are merely exemplary and can only be used to explain and illustrate the technical solution of the present invention, but cannot be construed as limiting the technical solution of the present invention.

[0023] like Figure 1As shown, the present application provides a filter rod with tar reduction, harm reduction and degradation functions. The filter rod can be applicable to any existing cigarette varieties and is not necessarily limited to filter rods for heat-not-burn cigarettes. The filter rod of the present application can be composed of only a single element of a functional rod, and the molding paper used to wrap the functional rod is not counted here. In other embodiments of the present application, the cigarette filter rod includes a plurality of elements wrapped in the form of rods using molding paper 3, but among these multiple elements, at least one element must be a functional rod 1, and as for the other elements, it can be one or more of an acetate fiber filter rod 2, a polylactic acid fiber filter rod, a paper filter rod, a reconstituted tobacco filter rod, an injection molded filter rod, a paper tube, and the like.

[0024] In the present application, the functional rods are made of materials that can reduce tar and harm and have degradable functions to meet green environmental protection requirements. Specifically, the functional rods are made of sheets, and the sheets are made of degradable fibers, or the sheets include degradable fibers.

[0025] In the present application, the degradable fibers include but are not limited to one or more of lyocell fibers, polylactic acid fibers, viscose fibers, bamboo pulp fibers, cotton pulp fibers, mahjong fibers, and wood pulp fibers. More specifically, lyocell fibers, as modified bio-based fibers, must be used as the raw material for the sheet.

[0026] In the present application, the functional bar is a bar with tar reduction, harm reduction and degradation functions. After the cigarette smoke passes through the functional bar, the tar and nicotine can be adsorbed by 0-80%, but usually more than 30%.

[0027] In the present application, the sheet material is a nonwoven fabric 4, the quantitative amount of the nonwoven fabric is 20-100g / m2, the breaking strength is 5-100N, and the thickness is 100um-1000um. Pits are evenly arranged on both sides of the sheet material, specifically, uniform pits are formed by punching the other side on both sides of the sheet material, that is, a protrusion is formed on the other side, and the shape of the protrusion can be cylindrical, multi-prism or any other shape, and the shape of the protrusion of the same sheet material to the two sides can be different or the same, and it is arranged adjacently, taking the design of the pits in rows as an example, a row of pits is located on one surface, and another row of pits is located on the other surface, arranged in sequence, and the arrangement in rows here does not limit whether it is horizontally arranged or vertically arranged. Of course, in other embodiments of the present application, the pits may not protrude to the other surface. The purpose of such pit design is that when the functional bar is made, the protrusions and pits increase the total surface area. At the same time, these protrusions are located in the longitudinal channel, which interferes with the flow of smoke, and the pits can store part of the smoke, thereby improving the adsorption effect of tar and nicotine.

[0028] In the present application, the functional bar includes a plurality of longitudinally extending channels, and has a porosity of 30%-90% in the longitudinal direction, and has a total area of ​​100-1000 mm2 per millimeter of axial length. Preferably, when the porosity is between 38%-80%, the total area is 200-700 mm2 per millimeter of axial length. In the present application, the circumference of the functional bar is between 15-28 mm, and the axial length is between 5-40 mm, which meets the size requirements of existing cigarettes. Of course, according to actual needs, this data can be changed as needed, and does not affect the implementation of the technical solution of the present application.

[0029] Although the present invention is described herein with reference to the illustrative embodiments of the present invention, it should be understood that those skilled in the art can design many other modifications and implementations, which will fall within the scope and spirit of the principles disclosed in the present application. More specifically, within the scope disclosed in the present application, multiple variations and improvements can be made to the components and / or layout of the subject combination layout. In addition to the variations and improvements made to the components and / or layout, other uses will also be apparent to those skilled in the art.
