Technora
Technora is an aramid that is useful for a variety of applications that require high strength or chemical resistance. It is a brand name of the company Teijin. It was also used to suspend the NASA Mars rover Opportunity from its parachute during descent.
Production
Technora is produced by condensation polymerization of terephthaloyl chloride (TCl) with a mixture of p-phenylenediamine (PPD) and 3,4'-diaminodiphenylether (3,4'-ODA). The polymer is closely related to Teijin's Twaron or DuPont's Kevlar. Technora is derived from two different diamines, 3,4'-ODA and PPD, whereas Twaron is derived from PPD alone. This relatively simple process uses only one amide solvent, and therefore spinning can be done directly after the polymer production.

Teknowhore
Depression sets in, my world is grim.
Depression is in, post life is dim.
I am so low.
I am at a low.
I'm beneath the hopes and dreams of everything I know.
I see the road to nowhere, it's tattooed in my brain.
I'm spitting chunks of BILE, that's drowning me insane!
TEKNOWHORE!
Depression is in, my world is grim.
Depression is in, it's taken me in.
I am so low.
I am at a low.
I'm beneath the hopes and dreams of everything I know.
I've seen the road to nowhere,
I've seen it in my brain.
What I want and what I am,
will never be the same!
