Cigarette FiltersAcetate tow is a key material in the production of cigarette filters. It is a type of acetate fiber that is spun into tow (a bundle of fibers) and used to make the filter portion of a cigarette. Acetate tow is widely used because of its ability to capture and filter certain components of smoke, such as tar and nicotine, while maintaining the structural integrity of the cigarette filter. 95% of cigarette filters are made of cellulose acetate, with the rest made of paper and rayon
Acetate fiber filament bundle (CA Tow) : A mainstream product, it has good adsorption, elasticity and formability. It is easy to degrade after combustion and has relatively high environmental friendliness.
Polypropylene Tow (PP Tow) : It has a relatively low cost, but its adsorption performance is slightly weak. It is mostly used in mid-to-low-end cigarettes or the economy market.
Special filament bundles: such as activated carbon composite filament bundles, biodegradable filament bundles, etc., are used in high-end or environmentally friendly cigarettes.
The role of acetate tow in cigarette filters
Filtering effect:
Acetate tow can effectively filter out a variety of harmful substances in cigarette smoke, such as tar and nicotine, thereby reducing the amount of harmful substances inhaled by smokers.
Structural support:
Acetate tow can maintain the shape and structure of the filter tip, making it less likely to deform during use, thereby ensuring the filtering effect.
Common materials:
Cellulose acetate is the most widely used material in cigarette filters, accounting for about 95% of the total filter tip
Characteristics of Acetate Tow
Biodegradability: Cellulose acetate is a biodegradable material, which means it can be naturally decomposed after use and has relatively little impact on the environment.
Good filtration performance: Cellulose acetate tow has good filtration performance and can effectively remove harmful substances in smoke.
Easy to process: Cellulose acetate can be processed into tows of various shapes and sizes, suitable for different types of cigarette filters
Application Fields
Cigarette manufacturing: Used in filter rod forming machines (such as HAUNI, MOLINS) to produce regular, thin or beaded cigarette filters.
New type of tobacco: Hollow or composite filters suitable for heat-not-burn (HNB) tobacco products.
Special uses: such as medical filtration materials, industrial adsorption materials and other derivative applications.
