It quickly replaced manila in a number of applications due to it’s superior strength, easy handling, and abrasion resistance as well as its resistance to most chemicals, ability to absorb shock loads, and longer life.
Contractors specify it for use in a number of fall arrest applications such as positioning lanyards and vertical lifelines, as well as in lifting applications such as cargo nets, slings, and tow lines which benefit from its strength, durability, and ability to absorb shock loads.
Nylon rope Specification Standards
While polyester and other synthetics have replaced ‘the original synthetic’ in some cases, especially where low stretch is important, it is still widely used in marine, industrial, recreational, climbing, and military applications, and is identified in a number of military specs:
MIL-C-17183B – a tubular (diamond) braided parachute cord.
MIL-R-1688F – a climbing rope used in mountaineering activities.
MIL-R- 17343D – twisted rope.
MIL- R-24050E -double braid rope (superseded by MIL-DTL-24050E).
MIL-C-43307B – solid braid – specified in a number of colors.
Please note: not all rope in these descriptions meet the above specifications, but can be produced to spec if ordered as such. A formal quotation is required here, as prices and quantity requirements may be higher and delivery times longer for these.
Relative ease of satisfying color requirements, especially for lower quantity orders, is one way nylon stands out vs. polyester : it can be dyed atmospheric pressure at not much above room temperature, while polyester requires temperatures well above boiling in pressurized vessels, generally with chemical assistance.
