Panox staple fiber/Preoxidized staple fiber

PANOX, also referred to as oxidized pan fiber, is an oxidized polyacrylonitrile (PAN) fiber renowned for its non-flammable properties. Unlike conventional fibers, PANOX does not burn, melt, soften, or drip when exposed to heat or flame. Recognized globally as an industry standard for non-combustible textile fibers, PANOX finds application across various fields as an effective safeguard against fire and heat hazards. With an impressive Limiting Oxygen Index (LOI) exceeding 45%, PANOX surpasses the combustion standards of other fibers, aligning with combustion class S-a as per DIN 66083.

PANOX is an excellent choice for textile processing, as it seamlessly integrates into standard textile machinery to produce needled or spun-laced nonwovens across a broad spectrum of weights. Its versatility extends to blending with other fibers like polyester, facilitated by specialized finishes that enhance its handling during textile processes. Nonwovens incorporating PANOX exhibit favorable finishing and coating properties, enabling the attainment of attributes such as oil and water repellency as well as adhesive characteristics. Thanks to its remarkable Limiting Oxygen Index (LOI) value, PANOX fibers boast non-flammability, offering end products exceptional fire resistance, impressive thermal stability, and effective thermal insulation.

Crimped PANOX fibers are made from continuous fiber tow. They are supplied with a special sizing that improves cohesion. Together with a carefully optimized crimp level, this ensures that carding processes run continually and reliably, with good productivity. Crimped staple fibers are available in a range of lengths to suit different non-woven processes and equipment.

Non-crimped staple fibers are used in compounding and molding applications to provide a textured surface appearance to interior components in automotive, rail, and marine applications. As well as improving the cosmetic appeal of these surfaces, the PANOX fibers also improve the fire protection and chemical resistance of these parts.
