Abstract
The utility model provides a non-woven fabrics slot paper filter rod relates to cigarette filter rod, includes filter core (1), interior wrapping layer (2), slot ply (3) and outer wrapping layer (4), slot ply (3) are made by the non-woven fabrics. The method has the advantages of easy forming of the groove, deeper depth of the groove, lower suction resistance, better coke reduction effect and the like. The non-woven fabric with high basis weight and high hardness is used as the raw material and is used as the groove paper, and deeper groove depth can be extruded due to the characteristic of higher hardness.
Description
Technical Field
The utility model relates to a filter rod for the cigarette, concretely relates to non-woven fabrics slot paper filter rod.
Background
Compared with the traditional filter stick, the grooved filter stick has the effect of reducing smoke tar, and the grooved filter stick is low in suction resistance and can be drawn out smoothly. The common grooved filter stick adopts cellulose paper as grooved paper, and is characterized in that the shape of the grooves is greatly influenced by the length of paper fibers, the depth of the grooves made of the cellulose paper is generally shallow, the appearance is not visual enough, and the generated suction resistance is relatively high.
Disclosure of Invention
The utility model aims to solve the technical problem that: in order to solve the problems, the non-woven fabric grooved paper filter stick is provided.
The technical solution of the utility model is that: the non-woven groove paper filter stick comprises a filter element, an inner wrapping layer, a groove paper layer and an outer wrapping layer, wherein the groove paper layer is made of non-woven fabrics.
The technical effects of the utility model are that: the method has the advantages of easy forming of the groove, deeper depth of the groove, lower suction resistance, better coke reduction effect and the like. The non-woven fabric with high basis weight and high hardness is used as the raw material and is used as the groove paper, and deeper groove depth can be extruded due to the characteristic of higher hardness. The transparent forming paper can visually see the groove structure from the end face and the cross section of the cigarette. Compared with the traditional outer groove filter stick, the cigarette section groove is deeper in depth and larger in groove area, and stronger visual impact is given to people. The grooves on the non-woven base paper are subjected to gridding treatment, and the oblique grooves and the longitudinal grooves are intersected on the longitudinal grooves to form intercept points. The appearance of the intercept point increases the times of smoke passing through the slot paper, and the tar reducing effect is increased. The thickness of the non-woven fabric can be increased by nearly one time compared with the thickness of the traditional cellulose paper, under the condition of the same circumference, the thickness of the paper is increased, the volume of the filter stick occupied by the tows is less, the suction resistance can be lower, and the suction effect is smoother.
Drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic view of the expanded structure of the groove paper layer of the present invention.
Detailed Description
As shown in fig. 1 and 2, the non-woven grooved paper filter stick comprises a filter element 1, an inner wrapping layer 2, a grooved paper layer 3 and an outer wrapping layer 4, wherein the grooved paper layer 3 is made of non-woven fabrics.
The grooves on the groove paper layer 3 are in a grid shape.
The grid shape is formed by the intersection difference of the inclined grooves 5 which are respectively at 45 degrees and 135 degrees relative to the axis.
The grooved paper layer 3 is also provided with a plurality of longitudinal grooves 6 arranged parallel to the axis.
The longitudinal grooves 6 are divided into segments in the axial direction, and after being cut into filters, each filter contains a segment of the longitudinal groove.
The depth of the groove is 0.4-1 mm.
The non-woven fabrics thickness that slot ply 3 adopted is 350um.
The outer wrapping layer 4 is made of transparent molding paper.
The filter element 1 is made of cellulose diacetate tow.
