Unusual item used as fabric

So, I was researching about fabric online and I found some weird shit. Among all I have found the most unusual item used as fabric is Fish Mucus.

There is a creature in the ocean known as the hagfish, and it secretes mucus/slime, which it uses to slip away from predators if captured. Not technically a fish, the hagfish has been around for about 500 million years, possibly due to the benefits their slime offers. Now those benefits extend to humanity. Douglas Fudge, a researcher at the University of Guelph, and his team have isolated threads from the hagfish’s slime and documented that it’s 10 times stronger than nylon. While it’s not yet commercially available, the slime is considered a far more economical fabric than other animal byproducts.
