Acetate tow is made of natural wood pulp, which is processed into cellulose acetate sheets through acetification. It is processed through dissolution, filtration, spinning, curling, drying and other production processes. It is a precision filtration material that can be used to make cigarette filters, ink pen refills, diapers' water-absorbing layers and non-woven fabrics for facial masks. Acetate tow is a regenerated cellulose with a fiber cross-sectional shape of "Y". The fiber has a large surface area, good filtration performance and good moisture absorption and adsorption. It is a "Y"-shaped fiber with a large surface area, good filtration performance and good moisture absorption and adsorption.
Diacetate fiber tow is a polymer material made from natural cellulose (wood, cotton linters, etc.) through acetification to diacetate cellulose and spinning. This material has a Y-shaped single-filament cross-section structure and has excellent hygroscopicity, air permeability and adsorption properties. It is mainly used in the manufacture of cigarette filters and can effectively intercept harmful components in smoke. Its chemical properties are stable, but the ester bond is easily destroyed by strong acids and alkalis. It also has thermoplasticity and good processability.
Core Features
Filtration efficiency: The fiber density and Denier per filament can be adjusted to control the tar retention rate (usually 8-15mg per piece).
Suction resistance performance: It affects the smoothness of smoking. It is necessary to balance the filtration effect and the comfort of suction.
Forming stability: High elasticity and compressive resistance ensure the integrity of the filter rods during high-speed production.
Safety and environmental protection: Complies with international standards such as FDA and EU, has no toxic residues, and some products are biodegradable.
Production Process
Spinning: Dissolve cellulose acetate and spin it into fibers.
Curling processing: Increase fiber fluffiness and enhance filtration efficiency.
Ribbon forming: After the fibers are combed and laid, a uniform filament ribbon roll is formed.
Slitting and packaging: Slitting into different widths as per customer requirements (such as 3.2Y/35000, 5.0Y/25000, etc.).
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.
