I make my own hemp, jute, bamboo-silk, and cotton ropes (I have a few others in the works but they are in the testing phase so coming soon), and when I vend at events I offer dyed nylon rope.
I’ve found after testing the different materials (natural vs. synthetic that is; testing each type of material against each other is another another post entirely) and… asking a few different people from different engineering backgrounds what could be attributed to the failure of synthetic vs. natural ropes that tend to be twisted in their construction vs. synthetic that tends to be braided.
Basicly the braided nylon rope allows for a more even wear and tear over the material over the life of the rope.
This information was brought to me by some friends at the United States Army Corps of Engineers and a mechanical engineer that I keep on staff here at Bastard Ropes. So if Ive butchered the re-telling of this info…oops.
