Antioxidant, UV Absorber, Optical Brightener and Pigments for PET Fiber

PET fiber is an abbreviation of polyethylene terephthalate fiber. polyester, acrylic and polyolefin fiber dominate the market. By volume, they account for approximately 98% of synthetic fiber production, with polyester alone making up more than 70%.

Features: High fracture Strength, Stable form, Crease resistance.

Main Application: Carpet, leather, fishing net, etc.

Pigment For PET Fiber

  1. Pigment shall meet 285-300℃ for 10-30min without color change.
  2. For dyes, it should have good sublimation resistance, bleeding resistance.
  3. Pigment of azo, bisazo, multi azo, isoquinoline, thioindigo, quinacridone chemistry is not suitable for coloring PET fiber.
  4. Pigment shall provide PET fiber good light resistance and abrasion resistance.
