Nylon is the strongest of the man made fibres in common use. It has excellent shock absorbtion, is not affected by wide variations in temperature, and is very elastic, stretching up to 46% before breaking. Due to its high stretch, however, it is prone to internal stretch abrasion (which is caused as the fibres scissor over one another as the rope extends and contracts) with hard use. Nylon is 1.14 times more dense than water and therefore sinks. Nylon makes an excellent anchor warp and light towing rope. It has other applications where a high strength shock resistant rope is required. Nylon rope has a shiny white appearance and when new, an oily feel. |
