Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dispersible cigarette filter which is easily dispersed by rainwater or the like when it is discarded in the environment after smoking.

[0002]

2. Description of the Related Art Conventionally, the structure of a cigarette filter made of a fiber bundle is such that a wrapping paper wound with an adhesive is crimped by several thousand or ten thousand. Fiber
The fibers were aligned and filled in the length direction, and the fibers were spot-welded to each other at many points by a plasticizer or the like. Further, the filter was formed of one filter material having a length of about 25 mm.

[0003]

However, since the fibers are welded at many points, the filter is not easily dispersed when the filter is no longer needed after smoking and is discarded into the environment. Since it retains its shape for a long time, it has drawbacks such as impairing the aesthetics of the environment. In addition, the filter
Is made of one filter material with a length of about 25 mm, so wrap the wrapping paper with a water-soluble adhesive,
The wrapping paper itself uses a water-dispersible paper or a sheet-like material made of a water-soluble material, and instead of welding the fibers together, a water-soluble adhesive is used for bonding, or no adhesive is used. Even if a fiber filter that is not adhered at all is used, if it is left outdoors, the paper wrapper will separate or disperse mainly due to rainwater, and the adhesive will also flow out, causing the fibers The shape of the filter collapses because the adhered parts of the filter separate, but the fibers do not disperse finely as a result of the entanglement of the fibers, and the filter does not easily disperse because it remains as one lump, Since the shape of the period is retained, there are drawbacks such as impairing the aesthetics of the environment.

It is an object of the present invention to provide a cigarette filter which is easily dispersed by the action of water such as rainwater in the environment even if it is discarded by mistake in the environment and does not spoil the aesthetics of the environment. .

[0005]

The present invention has been made to achieve the above-mentioned object, and crimped fibers are bonded with a water-soluble adhesive between fiber bundles or aligned without bonding. It is characterized in that it is composed of a plurality of filter materials having a length of 8 mm to 0.5 mm.

The fibers constituting the fiber bundle used in the present invention include, for example, cellulose acetate fiber, rayon fiber, polypropylene fiber, polyethylene fiber and the like, which are smokeable or processed into a filter. Cellulose acetate fibers are preferably used as the fibers constituting the fiber bundle because of their excellent properties.

The fineness of these single fibers is from 1 to
15 denier with a crimp of 15 to 5 per inch
It is 0. The fiber cross-sectional shape is Y. I. C. X. R-shaped ones are used. These monofilaments are 3,000-
1,000,000 bundles are bundled to form a fiber bundle used in the present invention.

The filter used in the present invention has a length of 8 mm to 0.5 in which crimped fibers are adhered with a water-soluble adhesive between fiber bundles or aligned without adhering.
A plurality of mm filter materials are used.

When the length of the filter material exceeds 8 mm, when the filter material is left outdoors, the wrapping paper is separated or dispersed mainly by rainwater and flows out, and the adhesive flows out to bond the fibers together. The shape of the filter collapses due to the separation of the parts that had been separated, but the fibers do not disperse finely as a result of being entangled with each other, and they remain as a single mass, so in the environment due to the action of water such as rainwater It does not achieve the object of the present invention to provide a cigarette filter which is easily dispersed and does not impair the aesthetics of the environment. Also, 0.5m
When the length is less than m, if the filter is formed to have a length of about 15 mm, the number of filter materials constituting the filter becomes too large and workability deteriorates.

The number of filter materials used in the present invention is determined by the length of the filter to be manufactured and the length of the filter material.

The water-soluble adhesive for adhering crimped fibers to each other in the fiber bundle used in the present invention is not particularly limited as long as the bonds between the fibers are mainly separated by rainwater, but for example, starch, Dextrin, glue, polyvinyl alcohol and partial acetalization products, polyacrylic acid amide, methyl cellulose, casein, carboxymethyl cellulose, hydroxyethyl cellulose, unsaturated carboxylic acid (salt) polymers and copolymers thereof, polymethyl vinyl ether, polyvinyl pyrrolidone, and them Examples thereof include aqueous solutions or emulsion solutions of high molecular substances such as the copolymers. Further, in the present invention, the crimped fiber bundle may be simply aligned without adhering the fiber bundle water-soluble adhesive.

The filter material and the cigarette of the present invention are wrapped with a wrapping paper, and as such a wrapping paper, addition of additives for imparting water resistance or post-treatment is not performed at all or reduced. Examples of the paper have a water-dispersing ability, such as filter-wrapping paper and toilet paper that have been conventionally used. The water-soluble adhesive may be used as the adhesive used for winding this. If a water-soluble material is used, the wrapping paper is separated from the filter material in a short period of time due to the loss of the adhesive due to rainwater, and the function of protecting the inside is lost, so that the filter material is easily dispersed, which is preferable. .

An example of the method for producing the dispersible cigarette filter of the present invention using acetate fibers as fibers will be described below with reference to the drawings. First, the crimped acetate fiber tow 2 is continuously taken out from the bale 1, air-opened by the first banding jet 3, and then further opened by the second banding jet 4 via the guide 6. After being fiberized, then mechanically pulled through a britishing roll 7, a feed roll 8 and a ratio roll 9, the fiber is opened, and further air-opened through a third banding jet 5, and then enters the plasticity adding device 26. In the plasticity adding device 26, the water-soluble adhesive is taken out from the pair of water-soluble adhesive tanks 27 and 28, supplied to the upper and lower brush rolls 33 and 34 by the gear pumps 29 and 30, and opened into fine droplets. Added to acetate fiber tow. 31,
Reference numeral 32 denotes each hose that supplies a water-soluble adhesive to the upper and lower brush rolls 33 and 34. The acetate fiber tow that has been opened and supplied with the water-soluble adhesive is taken up by the delivery roll 10 and guided via the air jet 11 to the tongs 12 for converging in a circular rod shape.

The wrapping paper 16 sent out from the wrapping paper bobbin 15 is wound around the outer periphery of the acetate fiber rod-shaped body which is fed from the air jet 11 to the tongue 12 and is converged into a circular rod shape. Gun 20
After joining with the hot melt glue supplied from the above and cooling in the cooling chamber-13 to complete the joining, it becomes a continuous rod-like body 35, which is cut into a predetermined length by the cutter 18 to obtain the filter material 36. To be 21
Is a nozzle for supplying a rail glue for fixing the rod-shaped fiber aggregate and the wrapping paper 16, 14 is a garniture belt for driving the rod-shaped molded body, and 17 is for driving the garniture belt 14. Drum boule, 19 is a catcher belt conveyor for conveying the obtained filter material 36. The resulting filter material 36 may be further cut.

A plurality of filters made in this way
As shown in FIG. 2, the cigarette filter 37 made of the material 36 has a filter material 36, which is made of the material A. Along with A, the plurality of filter materials 36 are combined and wound with one sheet of wrapping paper B, and further with one piece of wrapping paper C together with the tobacco portion 38, a dispersible cigarette filter-37 is obtained.
