Fiber Solution Systems Used in Real Manufacturing

Dope-Dyed Fibers

What it is

Carbon black is added directly into the polymer melt before spinning to permanently color the fiber.

Why it is used
Superior color fastness
No dyeing wastewater
Long-term shade stability

Common factory problems

  • Spinneret clogging
  • Fiber specks
  • Breakage during high-speed spinning

Key carbon black requirements

Ultra-fine dispersion
No agglomerates
Minimal spinneret wear
Stable color development
