Problems solved by technology

ZL200510024998.X announced the dry-laid paper cigarette filter rod and its preparation method. Because it cannot effectively deal with the problem of filter paper hair loss and powder loss, the inhalables cannot meet the use requirements. The suction resistance of the tip stick is difficult to control. Based on this, the same inventor revised the patent and applied for "Air-laid Cigarette Filter Stick and Its Preparation Method" (Application No. 200610024267.X). The improved technology uses Man-made fibers and / or man-made fibers, which are not accepted by the tobacco industry

Embodiment 1

[0017] The pure fluff pulp cigarette filter rod has a filter core composed of 60% fluff pulp and 40% cured latex.

[0018] The preparation method of pure fluff pulp cigarette filter rod comprises the following steps: (1) the fluff pulp is opened and humidified, then air-laid to form fluff pulp paper, and then hot-pressed at 90°C and 3kN / m; (2) The latex with a solid content of 10% is sprayed on the front side of the fluff pulp paper, and dried at 130°C after completion; (3) Continue to spray the reverse side of the fluff pulp paper with latex with a solid content of 10%, and dry at 135°C after completion, and then solidify The final latex is covered on the front and back sides of the fluff pulp paper; (4) into a roll, cut into a disc with a width of 120mm; (5) Unwind the disc, and when unrolling, carry out the process at intervals of 2 mm along the length of the fluff pulp paper. Indentation, the indentation is along the length of the filter rod, at an angle of 0° with the cen...

Embodiment 2

[0020] The pure fluff pulp cigarette filter rod has a filter core composed of 90% by mass of fluff pulp and 10% of cured starch glue.

[0021] The preparation method of pure fluff pulp cigarette filter rod comprises the following steps: (1) the fluff pulp is opened and humidified, then air-laid to form fluff pulp paper, and then hot-pressed at 140°C and 0.1kN / m; (2) Starch glue with a solid content of 15% is used for sizing the front surface of the fluff pulp paper, and dried at 200°C after completion; (3) continue to use starch glue with a solid content of 15% for sizing the reverse surface of the fluff pulp paper, and after completion, 220°C Drying, at this time, the cured starch glue covers the front and back of the fluff pulp paper; (4) rolls, cut into discs with a width of 140mm; (5) unroll the discs, along the length of the fluff pulp The indentation is carried out at intervals of 5mm in the length direction of the paper, and the indentation is along the length direction...

Abstract

The invention belongs to the technical field of cigarette filter rods, and specifically relates to a pure fluff pulp cigarette filter rod and a preparation method thereof. A filter element of the pure fluff pulp cigarette filter rod consists of 60 to 90 mass percent of fluff pulp and 10 to 40 mass percent of cured binding agent. The pure fluff pulp cigarette filter rod is prepared by adopting pure fluff pulp as a raw material, has strong filtering and absorptive capacity, can reduce the tar content very well to reduce harms caused by cigarettes to a human body; besides, the pure fluff pulp cigarette filter rod can be degraded naturally after being used and cannot cause harms to the environment.

Description

technical field [0001] The invention belongs to the technical field of cigarette filter rods, and in particular relates to a pure fluff pulp cigarette filter rod and a preparation method thereof. Background technique [0002] Fibrous tow filter rods, paper rods, nonwoven rods and composite rods are known in the industry. The raw material preparation equipment and process of fiber tow filter rod are complicated, the material cost is high and pollutes the environment during use, it is difficult to degrade naturally, and the filtration and adsorption performance is not good. The paper stick is severely deformed or even fiber disintegrated after being damp or absorbing moisture, so it cannot directly touch the mouth. Due to the addition of chemical fibers or artificial fibers to the filter material, non-woven rods have poor adsorption and filtration performance, and are not easy to degrade in the natural environment. Tar reduction and harm reduction in the tobacco industry hav...
