Abstract
The invention discloses a cigarette filter made of loofah sponge fiber. A filter cartridge of the cigarette filter made of the loofah sponge is composed of the loofah sponge fiber and cellulose acetate fiber. The loofah sponge fiber accounts for 10%-40% of the weight of the filter cartridge. And a preparation method of the cigarette filter made of loofah sponge filter is further disclosed. A better method is that the loofah sponge is dealt with alkalinity, or after alkali treatment, the loofah sponge is processed with chemical modified treatment. The cigarette filter has the advantages of being good in vent ability and effective in getting rid of injurious ingredient among cigarette smoke. Through the alkali treatment towards the loofah sponge and the modified treatment towards the loofah sponge, adsorption capacity of the loofah sponge and preferential adsorption of the loofah sponge are strengthened so that the loofah sponge can be applied to differently specific cigarette filters. The cigarette filter also has the advantages of being environment-friendly, light in weight, low in price, easy to gain and the like.
Description
Technical field
The invention belongs to field of cigarette producing technology, be specifically related to a kind of loofah fiber cigarette filter and preparation method thereof.
Background technology
Along with the raising of people to health concerns degree, " smoking is with healthy " problem more and more comes into one's own, the trend of cigarette development is also progressively adjusted into low tar future development, the cigarette of selling is on the market over more than 90% being cigarette with filter tip, conventional cigarette filter material for core is all generally to use acetate fiber or polypropylene bunch fiber at present, because the characteristic of acetate fiber and polypropylene bunch fiber is limit, be difficult to the harmful components in fully effective filtering cigarette smoke.
Luffa has unique absorption property, has hydrophily and oil loving double grading simultaneously.Luffa apparent density is about 0.77-0.78g/cm
3,, there is a large amount of ditch ridges in its surface irregularity, and ditch ridge size is about 1-5 μ m.With after alkali treatment, at the ditch ridge surface rising and falling, can produce a large amount of holes.The cellular structure that it has is given its good characterization of adsorption, and under comparatively dry condition (RH is less than 45%), luffa still can adsorb 10% moisture; Meanwhile, luffa not only has stronger characterization of adsorption to hydrophilic metal ion, and it also has good absorption property to organic matters such as hydrophobic aromatic hydrocarbon.In addition luffa is carried out to suitable chemical modification, can also change its lypohydrophilic character, thereby strengthen its special suction-operated.
Summary of the invention
The object of the invention is the deficiency for existing cigarette filter, according to the absorption property of luffa uniqueness, provide a kind of new cigarette filter, the present invention also provides its preparation method.
For achieving the above object, the present invention is by the following technical solutions:
A cigarette filter, the filter core of described cigarette filter is comprised of loofah fiber and acetate fiber, and described loofah fiber accounts for the 10-40% of filter core weight.
Preferably, described loofah fiber accounts for 15% of filter core weight.
A preparation method for loofah fiber cigarette filter, comprises the following steps: acetate fiber is mixed to loofah fiber, and boundling, curling, dry, makes blend fibre tow; Then by the gluing of blend fibre tow, moulding, cuts off, and makes filter core; Finally on filter core, wrap up forming paper, wherein, described loofah fiber accounts for the 10-40% of filter core weight.
Preferably, described loofah fiber accounts for 15% of filter core weight.
Luffa directly can be made to fiber, also luffa can be carried out making fiber after basic treatment, luffa can also be carried out to proceed chemical modification after basic treatment and make fiber.
The first preparation method of loofah fiber provided by the invention carries out alkali treatment by luffa and makes: luffa is immersed in the NaOH ethanol solution that concentration expressed in percentage by weight is 10-50%, stirring reaction 1-48h at 20-75 ℃, then use 500-700W microwave intermittent radiation after 10-20 minute, the 0.5-3 hour that refluxes in 80 ℃ of waters bath with thermostatic control, washing luffa, oven dry, moulding after filtering.
The second preparation method of loofah fiber provided by the invention carries out luffa to proceed esterification treatment and make after alkali treatment: luffa is immersed in the NaOH ethanol solution that concentration expressed in percentage by weight is 10-50%, stirring reaction 1-48 hour at 20-75 ℃, then use 500-700W microwave intermittent radiation after 10-20 minute, 0.5-3 hour refluxes in 80 ℃ of waters bath with thermostatic control, washing luffa after filtering, in acetic anhydride, soak 1-48 hour, with 500-700W microwave intermittent radiation 10-20 minute, washing luffa, oven dry, moulding after filtering.
The third preparation method of loofah fiber provided by the invention carries out luffa to proceed etherificate processing and make after alkali treatment: luffa is immersed in the NaOH ethanol solution that concentration expressed in percentage by weight is 10-50%, stirring reaction 1-48 hour at 20-75 ℃, then use 500～700W microwave intermittent radiation after 10-20 minute, 0.5-3 hour refluxes in 80 ℃ of waters bath with thermostatic control, washing luffa after filtering, then the NaOH solution that is 6-10% by concentration expressed in percentage by weight fully infiltrates, adding gradually concentration expressed in percentage by weight is the chloroacetic acid ethanol solution of 30-60%, the consumption of chloroacetic acid is the 10-90% of luffa weight, at 50-100 ℃, react 1-24h, be cooled to room temperature, washing luffa after filtering, dry, moulding.
Beneficial effect of the present invention: the cigarette filter that the present invention makes has good aeration, and effective harmful components in filtering cigarette smoke, after luffa alkali treatment and chemical modification are processed, can strengthen its adsorption capacity and strengthen its selective absorption characteristic, can be used for difference cigarette filter targetedly.Because luffa is biodegradable and regeneration, so the present invention is conducive to environmental protection, also has the advantages such as light weight is cheap and easy to get simultaneously.
