Natural fibre shibari rope friction test

This was made in order to settle some debate about the causes of failure of bondage rope. In another video, we were shown how synthetic rope could easily be cut using friction. In this example, the static part was cut due to the heat generated by friction. I wanted to test if my belief that natural fibre behaved differently was correct. The tests that I carried out with natural fibre produced quite different results with failure occurring on the moving part. With natural fibre, a higher speed is require to generate heat, so I assume most damage was due to abrasion. The looser the lay of the rope and the less dense, the faster the wear. The drier, the faster, with a lot of dust and squeaking due to lack of lubrication being created just before failure. I assume that the batching oil used in processing the fibre provided some residual lubrication which was quickly burned off by friction. Adding lubrication in the form of wax reduced friction and extended life. Jute wore faster than a very tight linen hemp with a high yarn count (40 per ply) by a factor of several times. This rope also exhibited greater strength during load tests. The ropes tested were: Asanawa, Osaka, Tossa and Amanawa (linen hemp).

It is very easy for friction and shock loads to induce failure, even with doubled rope and a light model. For safety advice, see www.esinem.com
