Where to buy Kevlar monofilaments?

[geneiusxie]

I need to get a spool of a single Kevlar 49 fiber (I can use Kevlar 29 if it's my last option)
Does anyone know any suppliers? If I can't get a single Kevlar fiber on a thread, does anyone sell extremely thin threads on spools of the stuff?

Also, does anyone know where to get carbon fiber in single filaments? I want high strength (around 4900MPa) something like Hexcel AS4 at least.

Also, where can I get nylon, polyester, and Vectran HT and HM monofilaments? (Or at least, extremely thin threads like, >0.05mm thick)
