Abstract

The present invention relates to a smog filtering material, particularly to a cigarette filter tip. The present invention comprises a filter tip which is matched and connected with a cigarette, filtering fibers are filled in the filter tip, and the surface of the filtering fiber is provided with a coating layer of a cellulose diacetate adhesive, and colors, perfumes, mineral substances, Chinese herbal medicines and chemicals can be added into the cellulose diacetate adhesive. The products of the present invention can filter out the substances harmful to human health of the cigarettes, and improve cigarette grades. Furthermore, the present invention which can be prevented from being counterfeited can be used as air filtering materials.

Description

The third fine filter stick of coated cellulose diacetate adhesive

The present invention relates to a kind of smoke filtration material, particularly cigarette filter.

In the prior art:

One, Celluloseacetate cigarette filter tow is made cigarette filter, but the cost of Celluloseacetate cigarette filter tow is higher 3 times than general polypropylene tows.

Two, polypropylene tows is made cigarette filter, jealous poor, bunchy type not.

Three, polypropylene tows is sprayed certain macromolecule adhesive and is made filter stick bunchy type, this product will be through oven dry, though the filter stick bunchy, so not contain the cellulose diacetate material jealous poor because of employed various macromolecules, the cigarette filter of making not as Celluloseacetate cigarette filter tow.

Cigarette filter of the present invention is the patent CN1224039A in the applicant's invention, application number 98110621.8 products, add required shades of colour in its product improvement, spices, mineral matter, Chinese herbal medicine and chemicals, the material that can remove harmful human body in the flue gas targetedly plays a role in health care.This product also can be used on air filting material.

For achieving the above object, the present invention adopts following technical proposals;

The same filter tip that is connected with the cigarette coupling that includes of cigarette filter of the present invention with existing technology, filling filter fiber tow in the filter tip, the surperficial coated that it is characterized in that its filter fiber tow has the cellulose diacetate adhesive and add color in the cellulose diacetate adhesive, spices, mineral matter, Chinese herbal medicine, chemicals.

The present invention has following conspicuous outstanding feature and remarkable advantage compared with prior art:

Coated has its performance of polypropylene tows filter stick of cellulose diacetate adhesive with equaling the Celluloseacetate cigarette filter tow filter stick.

Add required color in the cellulose diacetate adhesive, coated is made filter stick at polypropylene tows, just can make the filter stick of formulating certain color in fixed date, and the cigarette of making can the decisive prevention fake products that plays.

Add the spices coated and make filter stick at polypropylene tows in the cellulose diacetate adhesive, it is jealous and can make the flavoured type cigarettes of the different market demands that the cigarette of making can change low gear cigarette.

Add the filter stick that mineral matter (routine sepiolite powder) coated is made at polypropylene tows in the cellulose diacetate adhesive, the cigarette of making is 3,4 BaP materials of harmful human body in the filter cigarette effectively.

Below illustrate with example:

The cellulose diacetate adhesive coated of the weight 15%, 20%, 25% of example one, polypropylene tows filter stick is on polypropylene tows, and the performance of making filter stick is identical with the Celluloseacetate cigarette filter tow filter stick.

Coated was made filter stick after the weight ratio of example two, the edible pigment 0.01%-0.1% of usefulness was added in and mixes thoroughly in the cellulose diacetate adhesive on polypropylene tows, can be made into the shades of colour cigarette with filter tip.

Example three, with the weight ratio of edible peppermint ester 0.5%-5% be added in stir in the cellulose diacetate adhesive enter hermetically sealed can rapidly after 20 minutes and deposit 48 hours after, coated is made filter stick on polypropylene tows, can be made into cooling taste type cigarette.

Example four, in the cellulose diacetate adhesive, add stir evenly 30 minutes in 0.2% citric acid, 0.05% heavy water and the cellulose diacetate adhesive after, coated is made filter stick on polypropylene tows, make to produce 3,4 above BaPs 60% of 1.2 micrograms after cigarette can be reduced per 100 combustions of former cigarette.

Example five, be added with sepiolite powder (pH value neutrality) weight ratio 4%-9% stir evenly coated make filter stick on polypropylene tows in the cellulose diacetate adhesive, it can adsorb 3,4 BaPs 30% in the flue gas to make cigarette.

Claims

1. third fine filter stick that is used for the coated cellulose diacetate adhesive on the cigarette, comprise the filter tip that is connected with the cigarette coupling, filling filter fiber in the filter tip, there is the coat of cellulose diacetate adhesive on the surface of filter fiber, it is characterized in that mixing in the cellulose diacetate adhesive that to contain weight ratio be that to contain weight ratio be that to contain weight ratio be 4%～9% sepiolite powder or mix that to contain weight ratio be 0.2% citric acid and 0.05% heavy water for 0.5%～5% edible peppermint ester or mix for 0.01%～0.1% edible pigment or mix.
