Acetate Tow is a continuous tow fiber made of cellulose acetate, mainly used in cigarette filters, textile fabrics, functional non-woven fabrics and other fields. Acetate is a regenerated cellulose fiber derived from natural cotton linters or wood pulp, processed through acetification, spinning and other steps, and has excellent biocompatibility, air permeability and filtration performance.
The unique properties of acetate tow determine its irreplaceable position in the cigarette industry. It is the main raw material for manufacturing filters. More than 95% of cigarette filters in the world use acetate tow as the base material. At the same time, with the improvement of environmental awareness, the degradability and natural properties of acetate have led to its continuous expansion in the fields of textiles and new materials.
Production process
Acetification reaction: Using wood pulp or cotton linters as raw materials, cellulose is acetified by the catalytic action of acetic anhydride, acetic acid and sulfuric acid to obtain cellulose acetate.
Ripening and deacidification: Control the temperature and time to make the cellulose esterification degree uniform, and then remove the acidic by-products through washing and neutralization.
Dissolution and filtration: Dissolve cellulose acetate in a mixed solvent (such as acetone) to form a viscous and transparent spinning solution, which is then filtered through multiple stages to remove impurities.
Dry-wet spinning: The spinning solution is extruded into filaments through a spinneret. After part of the solvent is evaporated in hot air, the filaments enter a coagulation bath and are solidified into shape.
Drawing and doubling: After drawing the monofilament to the required fineness, it is drawn into a tow and an appropriate amount of fiber oil is added to improve its antistatic and processing properties.
Rolling, cutting and packaging: Cut and package the tow according to requirements to make cigarette tow or other products of different specifications
Features
Natural source, renewable
Using natural plant fibers as raw materials, it has good ecological and environmental protection characteristics and has greater sustainable development potential than petrochemical synthetic fibers
01
High filtration efficiency
The tow fibers are tightly arranged and have a stable pore structure, which can effectively filter tar and particles in the smoke, meeting the modern cigarette industry's demand for low-harm.
02
Highly degradable Acetate fiber can be slowly degraded in the natural environment without causing "white pollution", and is an environmentally friendly material that can replace traditional plastic fibers.
03
Good skin-friendliness
The fiber cross-section is soft and round, and does not irritate the skin. It is suitable for textile and fabric processing, such as high-end underwear, ties, curtain fabrics, etc.
04
Excellent processing suitability
The finished tow fiber has high strength, antistatic, good moisture absorption and air permeability, and is suitable for high-speed winding machine operation and various dyeing and finishing processes.
05
Main application areas
Cigarette filter manufacturing
Currently, the filters of most cigarettes in the world are made of acetate fiber tow, especially in mid-to-high-end cigarettes. Different shapes of tow (such as Y-shaped and X-shaped) can be customized according to the needs of cigarette brands to improve the smoking experience and filtering effect.
01
Medical and industrial filter materials
Can be used for industrial purposes such as air filtration and liquid filtration, and also used in sanitary products such as disposable medical masks and high-efficiency filters
02
Textile Industry
In the textile field, acetate fiber can be processed into acetate filament or staple fiber to make fabrics with a silky feel, which are suitable for clothing, home textiles, curtains and other fields, and are especially favored by high-end clothing brands.
03
Non-woven fabric materials
The tows after opening and combing can be used to prepare biodegradable non-woven fabrics, which are the preferred natural materials for wet wipes, facial masks, feminine hygiene products, etc.
