Acetate fiber filter
Since the introduction of cigarette filters 50 years ago, acetate fiber has occupied a significant position and is the most unusual material in the production cycle, even for the well-known conservative cigarette industry. Undoubtedly, acetate fiber has become a widely accepted mechanical filter for low tar and high tar cigarette consumers. In recent years, due to acceptability and commercial demand in the market, the thickness or specifications of acetate fiber have increased from 1.8 deniers to 5.0 deniers. This enables it to be made into a series of filter nozzles that adapt to different pressures and retention characteristics. In short, the finer the fiber, the higher the filtration efficiency of the cigarette filter tip.
Without the ventilation function of the filter tip, acetate fiber may still not be the most important material, as the performance of this material exceeds acceptable characteristics due to the needs of cigarette design and low tar volatile cigarettes. However, the emergence of filter ventilation function reduces the volatilization of smoke, including carbon monoxide that cannot be reduced through other measures, and reduces cigarette pressure drop, which in a sense is the pressure to remove acetate fibers.
The volatilization of cigarette tar and nicotine decreases with the growth of the filter tip. Twenty years ago, filter tips were usually 20 millimeters long, and filter tips 25 millimeters, 27 millimeters, and even 31 millimeters long were common. The increase in filter nozzle length not only reduces the tobacco content in cigarettes, but also reduces the smoke generated by smoking cigarettes. The longer the filter nozzle, the better the effect of reducing smoke
