There are some Youtube videos out there on synthetic braided ropes, crazy to watch. I tried making braided jute rope apart of my repertoire at BastardRopes.com but its just not time/cost effective, but it would increase the strength I imagine, but never had it tested.

But I was referring to solid braided nylon 1/4(6 mm) rope not twisted nylon.
My bad didn’t clarify. But no they didn’t even have an outter sheath like you’d find on climbing ropes that are often used today.

Theres tons of really useful information on the construction and production of nylon rope rope twisted and braided. The history is fascinating. What’s less fascinating is the addition of poly fiber to nylon rope a few years ago. Unrelated but still annoying.

Cheers to all,
