For anyone involved in the procurement or development of cigarette filters, a deep understanding of the technical specifications of Cellulose Acetate Tow is essential. These specifications, particularly denier and tenacity, directly dictate the performance characteristics of the final filter rod. As a seasoned manufacturer and supplier of industrial-grade Cellulose Acetate Tow, we often guide our B2B clients through these critical details. This article serves as a technical primer, explaining what these specifications mean and why they matter when you are looking to buy high-quality material.

Denier is a unit of linear mass density for fibers. It measures the mass in grams per 9,000 meters of fiber. A lower denier indicates a finer fiber, while a higher denier means a coarser fiber. In Cellulose Acetate Tow, denier is often expressed as 'Y' (e.g., 2.5Y, 3.0Y), which refers to the denier per filament. The total denier of the tow (e.g., 30,000, 35,000) is the sum of the deniers of all filaments bundled together. The combination of filament denier and total denier influences the tow's bulk, softness, and filtration efficiency. For example, a higher total denier tow generally results in a more voluminous filter rod, which can affect draw resistance and filtration capacity. Understanding these relationships is vital when selecting the right specification from a manufacturer.

Tenacity, measured in grams per denier (g/d), refers to the tensile strength of the fiber. It indicates how much force the fiber can withstand before breaking. For Cellulose Acetate Tow used in cigarette filters, adequate tenacity is crucial to ensure the fibers do not break or degrade during the high-speed manufacturing process of filter rods. Our product, with CAS No. 9004-35-7, is manufactured to meet specific tenacity requirements, typically expressed as a minimum value (e.g., ≥7 N/Ktex). This ensures the tow can be processed reliably and consistently, leading to durable filters.

Other important specifications often encountered when sourcing Cellulose Acetate Tow include moisture content (typically kept below 6% to prevent processing issues), oil content (within a specified range like 0.8%-1.5% to ensure proper fiber lubrication), and TiO2 content (used as a brightener, usually around 0.5% or higher). Coil number and section figure of fiber are also critical quality indicators. As a manufacturer, we meticulously control these parameters to ensure our Cellulose Acetate Tow meets the rigorous demands of the industry. When you buy from us, you can trust that these specifications are consistently met, providing you with predictable performance.
