Problems solved by technology

[0002] As people pay more and more attention to health, the issue of "smoking and health" has been paid more and more attention, and the development trend of cigarettes has been gradually adjusted to the direction of low tar. More than 90% of the cigarettes sold on the market are filter cigarettes At present, the commonly used cigarette filter element materials are generally acetate fibers or polypropylene tow fibers. Due to the limited characteristics of acetate fibers and polypropylene tow fibers, it is difficult to fully and effectively filter out harmful components in cigarette smoke.

Embodiment 1

[0017] A cigarette filter, the filter element of the cigarette filter is composed of loofah fiber and acetate fiber, and the loofah fiber accounts for 10% of the weight of the filter element.

[0018] The loofah fiber is prepared by the following method: the loofah fiber is immersed in a 50% NaOH absolute ethanol solution, stirred at 75°C for 1 hour, and then irradiated with a 500 microwave intermittently for 20 minutes Afterwards, reflux in a constant temperature water bath at 80°C for 3 hours, filter and wash the loofah, soak in acetic anhydride for 24 hours, irradiate with 600W microwave intermittently for 10 minutes, filter and wash the loofah, dry and shape.

[0019] The preparation method of the cigarette filter in this embodiment is:

[0020] (1) Blend acetate fiber with loofah fiber, bundling, crimping, and drying to make blended fiber tow;

[0021] (2) Glue, shape and cut the blended fiber tow into a filter element;

[0022] (3) Wrap molding paper on the filter element.

Embodiment 2

[0024] A cigarette filter, the filter element of the cigarette filter is composed of loofah fiber and acetate fiber, and the loofah fiber accounts for 40% of the weight of the filter element.

[0025] The loofah fiber is prepared by the following method: the loofah fiber is immersed in a 10% by weight NaOH absolute ethanol solution, stirred for 48 hours at 20°C, and then irradiated with 700W microwave intermittently for 10 minutes Afterwards, reflux in a constant temperature water bath at 80°C for 0.5 hours, filter the loofah, wash, dry, and shape.

[0026] The preparation method of the cigarette filter in this example is the same as that of Example 1.

Embodiment 3

[0028] A cigarette filter, the filter element of the cigarette filter is composed of loofah fiber and acetate fiber, and the loofah fiber accounts for 15% of the weight of the filter element.

[0029] The loofah fiber is prepared by the following method: immersing the loofah in a 30% NaOH absolute ethanol solution with a concentration of 30% by weight, stirring and reacting at 50°C for 24 hours, and then intermittently irradiating with a 600W microwave for 15 minutes Then, reflux in a constant temperature water bath at 80°C for 2 hours, filter and wash the loofah, and then fully infiltrate it with 8% by weight NaOH solution, and gradually add 50% by weight monochloroacetic acid anhydrous ethanol solution, one The amount of chloroacetic acid used is 50% of the weight of the loofah, reacted at 70°C for 5 hours, cooled to room temperature, filtered, washed, dried, and shaped.

[0030] The preparation method of the cigarette filter is the same as in Example 1.

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 [0001] The invention belongs to the technical field of cigarette manufacturing, and specifically relates to a loofah fiber cigarette filter tip and a preparation method thereof. Background technique [0002] As people pay more attention to health, the issue of "smoking and health" has been paid more and more attention, and the development trend of cigarettes has gradually adjusted to the direction of low tar. More than 90% of the cigarettes on the market are filter cigarettes At present, the commonly used cigarette filter element materials generally use acetate fiber or polypropylene tow fiber. Due to the limitation of the characteristics of acetate fiber and polypropylene tow fiber, it is difficult to fully and effectively filter out harmful components in cigarette smoke. . [0003] Loofah has unique adsorption properties, as well as the dual characteristics of hydrophilicity and lipophilicity. The apparent density of loofah is about 0.77-0.78g / cm 3 , Its surface...
