Embodiment 1

[0016] The present invention comprises the following steps:

[0017] (1), after blending the acetate fiber with the hollow fiber, bundle, crimp, and dry to make a blended fiber tow, wherein the weight percentage of the hollow fiber and the acetate fiber is: 50% of the hollow fiber, 50% of the acetate fiber; the hollow fiber has added 1% osmanthus fragrans extract by mass percentage; the osmanthus fragrans extract is extracted with 5% ethanol and concentrated to a relative density of 1.2.

[0018] (2), the blended fiber tow is glued, shaped, and cut to make the blended fiber filter element;

[0019] (3) Wrap molding paper and tipping paper on the blended fiber filter element at one time.

[0020] Wherein said fruit extract is banana, apple, strawberry, grape, watermelon or Hami melon extracted with 95% ethanol and then concentrated to a relative density of 1.2. The Chinese herbal medicine extract is extracted from licorice, sweet-scented osmanthus, wolfberry or astragalus wit...

Embodiment 2

[0023] The present invention comprises the following steps:

[0024] (1), after blending the acetate fiber with the hollow fiber, bundle, crimp, and dry to make a blended fiber tow, wherein the weight percentage of the hollow fiber and the acetate fiber is: 25% of the hollow fiber, 75% of the acetate fiber; the hollow fiber has added 0.5% licorice extract by mass; the licorice extract is extracted with 75% ethanol and concentrated to a relative density of 1.2.

[0025] (2), the blended fiber tow is glued, shaped, and cut to make the blended fiber filter element;

[0026] (3) Wrap molding paper and tipping paper on the blended fiber filter element at one time.

Embodiment 3

[0028] The present invention comprises the following steps:

[0029] (1), after blending the acetate fiber with the hollow fiber, bundle, crimp, and dry to make a blended fiber tow, wherein the weight percentage of the hollow fiber and the acetate fiber is: 50% of the hollow fiber, 50% of the acetate fiber; the hollow fiber has added Strawberry extract with a mass percentage of 5%; the strawberry extract is extracted with 95% ethanol and concentrated to a relative density of 1.2.

[0030] (2), the blended fiber tow is glued, shaped, and cut to make the blended fiber filter element;

[0031] (3) Wrap molding paper and tipping paper on the blended fiber filter element at one time.

Abstract

The invention relates to a method for preparing a hollow fiber cigarette filter tip, which comprises the following steps of: (1) after doping hollow fibers into acetate fibers, bundling, curling and drying to obtain a mixed fiber bundle, wherein the mixed fiber bundle comprises 25-50 percent of hollow fibers and 50-75 percent of acetate fibers in percentage by weight: adding 0.5-5 percent by mass of fruit extract liquid or 0.5-5 percent of Chinese herbal medicine extract liquid into the hollow fibers; (2) sizing, forming and cutting the mixed fiber bundle off to obtain a mixed fiber filter core; and (3) coating forming paper and Chinese cypress paper on the mixed fiber filter core once. The cigarette filter tip prepared by using the method disclosed by the invention has high air permeability and can effectively filter harmful substances in smoke and meet the slow release of aroma so as to maintain the aroma for a long time.

Description

technical field [0001] The invention relates to a method for preparing a cigarette filter, in particular to a method for preparing a hollow fiber cigarette filter. Background technique [0002] Nowadays, cigarettes are generally equipped with filter tips. Commonly used cigarette filters generally use acetate fiber or acrylic fiber as the filter element. Due to the limited characteristics of the fiber, it is difficult to fully and effectively filter the harmful components in the smoke. At the same time, in order to improve the taste, more and more flavors and fragrances are introduced into cigarettes, mostly by adding flavors to tobacco leaves, recombined tobacco leaves, aluminum foil paper, etc. The purpose of increasing flavor is achieved, but there are generally problems such as a large consumption of spices, and cigarettes cannot maintain fragrance for a long time after the package is opened. Contents of the invention [0003] The object of the present invention is to ...
