Antioxidant, UV Absorber, OBAs and Pigments for PAN Fiber
PAN fiber is an abbreviation of Polyacrylonitrile fiber. Polyester, acrylic, and polyolefin dominate the synthetic fiber market. By volume, they account for approximately 98% of synthetic fiber production, with polyester alone making up more than 70%.
Features: poor abrasion and fatigue resistance, good weather resistance, good chemicals (Inorganic acid, peroxide) resistance.
Main Application: widely used in replacement of wool to make carpet, outdoor textile.

Pigment For PAN Fiber
There are two methods for coloring PAN fiber spun-dyeing;
- The first is pigment resolve in the dispersion which needs pigment to be solvent resistance; the other is concentration which polyacrylonitrile as a binder, pigment compatibility with polyacrylonitrile resin.
- Pigment need to be acid and alkali resistant.
- Pigment provide light resistance for colored fiber.
