Problems solved by technology

That is to say, if the pressure drop is too high, smokers will find it difficult to accept it due to the excessive resistance to draw, and if the pressure drop is too low, it will also limit the filtration efficiency of nicotine and glycerin to a certain extent.

Embodiment 1

[0028] In this example, diacetate fiber tow with a single denier of 23 denier and a total denier of 28,000 denier is introduced into a KDF4 / AF4 cellulose acetate filter rod forming machine, and 9.6% triacetin is applied to make a cellulose acetate filter rod . Such as figure 1 As shown, diacetate fiber tow 1 is fed from the feed inlet not shown in the figure, and then passes through the air-assisted opener 2, the pretension roller group 3, the feed roller group 4, the opening roller group 5 and the opener 15 enters the plasticizer spraying chamber 6, sprays 9.6% glycerol triacetate in the plasticizer spraying chamber 6, then continues to pass through the conveying roller group 8 and the wedge roller group 9, and is finally transported to the molding machine not shown in the figure , and made into cellulose acetate filter rods.

[0029] Processing circle 21.80-24.40mm cellulose acetate filter rod, the length of the filter rod is 132mm, no corrosion on the surface of cellulos...

Embodiment 2

[0031] Compared with Embodiment 1, this embodiment also adopts diacetate fiber tow with 23 deniers and a total denier of 28000 deniers in the present invention. The difference is that 15.8% triacetin is applied to make acetate fibers For the filter rod, no corrosion phenomenon was found on the surface of the cellulose acetate in the experiment, and other indicators remained unchanged.

Embodiment 3

[0033] Compared with Embodiment 1, this embodiment also adopts diacetate fiber tow with 23 deniers and a total denier of 28000 deniers in the present invention. The difference is that 28.7% glyceryl triacetate is applied to make acetate fibers For the filter rod, no corrosion phenomenon was found on the surface of the cellulose acetate in the experiment, and other indicators remained unchanged.

Abstract

The invention relates to an acetate fiber filter stick and the application thereof. The acetate fiber filter stick is composed of a fiber base material and a plasticizer. The application comprises thesteps of introducing the fiber base material into a filter stick forming unit; plasticizer addition preparation, wherein the single denier of the fiber base material is 20-25 deniers and the total denier of the acetate fiber tows is 26000-35000denier, and the total denier of the acetate fiber tows is 26000-35000denier. The fiber base material can bear 15%-45% of plasticizer, the pressure drop andhardness of the filter stick are fixed, and the filtering efficiency is changed by adjusting the content of the plasticizer in the filter stick, so that the acetate fiber filter stick capable of improving the nicotine filtering efficiency can be provided on the premise that the pressure drop and hardness are fixed.

Description

technical field [0001] The invention belongs to the field of tobacco, and relates to a cellulose acetate filter rod and an application thereof. Background technique [0002] Acetate filter sticks are generally used as cigarette filters. The fiber substrate of acetate filter sticks in the prior art generally uses conventional 3.0-5.0 denier tows, and diacetate tows with a total denier of 26000-35000 deniers. The amount of added plasticizer is generally no more than 15% (percentage by weight). After applying 15-18% plasticizer, the cellulose acetate surface has appeared erosion phenomenon, such as Figure 4 shown, which in turn affects the performance of cellulose acetate filter rods. In addition, adding a plasticizer (usually glycerol triacetate) on the opened tow belt to bond the fibers together can increase the hardness of the formed cellulose acetate filter rods. . [0003] Cigarette filter pressure drop is an important design parameter because smoke filtration efficiency...
