The core material of cigarette filters is cellulose acetate. More than 95% of commercial cigarette filters use this material. Why choose cellulose acetate as the core raw material?

1. Excellent fiber structure

Cellulose acetate can be processed into bundles composed of countless extremely fine fibers.

These fibers form a dense and complex three-dimensional network structure, which can effectively intercept solid and liquid particles in flue gas, mainly tar, through mechanical collision, diffusion, and inertia.

2. Good selective adsorption ability

It has weak adsorption capacity for water vapor, which means it will not excessively affect the "wetness" of the flue gas.

But it has good physical adsorption capacity for organic compounds such as tar and nicotine, which can effectively capture these substances.

3. Non toxic and odorless, high safety

Cellulose acetate itself is non-toxic, odorless, and biologically inert. It is widely used in fields such as eyeglass frames, film, textiles, etc. It is safe to come into contact with the human body.

In the case of insufficient combustion (such as at the end of smoking), it will only carbonize and will not burn violently to produce flames, making it relatively safe.

4. Strong processability

The filtration efficiency can be precisely controlled by adjusting the single filament density of the fiber bundle. The lower the linear density, the finer the fibers, and the stronger the filtering effect, but the suction resistance will also increase accordingly.

Easy to produce on a large scale and at low cost.
