kevlar cave line?

[tanto]

Is anyone using kevlar cave lines in case superior strength or abrasion resistance is needed?
Or, what's the best cave line for abrasion resistance?
Thanks.

Kevlar line is a very bad choice for caves and diving in general.
It's extremely hard to cut, when knotted it's hard to get out and will leave a burn if you let it slide through your hand.

OK, so which is the best for abrasion resistance?

[DR2K]

Cave divers normally use #24 braided nylon and wreck divers prefer # 36 braided nylon.
Safe and happy diving.

Exactly, and when it gets frayed change it. But it may take years.

If you need something stronger or more resistant than braided nylon, try a nylon kernmantle cord. It might also help to place some sort of pad at key rub points where the line come in contact with the rock. Obviously if you see it being worn through at the same spot...

You'll come out a lot cheaper in any case that's for sure, kevlar and spectra are not cheap to work with. There are a number of different kernmantle sheath/core combinations to provide different strength/abrasion resistance characteristics. For instance for a cave diving line you're not really concerned about it being load bearing (a person hanging off it) but you want good abrasion resistance.

Anyone have any good recomendations on materials and diameters? I believe polpropylene sheaths over a nylon core provide a good combo, but may be too buoyant.

Kevlar isn't compatible with lots of other lines. It's better to stick with braided nylon.

I've put 6 mm Kevlar kernmantle polyester cored stuff through a number of sumps. It is difficult to cut and knots tend to slip in it. Doen't make a good haul line either.

Or, what's the best cave line for abrasion resistance?

Stainless steel chain or wire.

You should ask the Germans about stainless steel wire

They now carry wire cutters to deal with the stainless wire left there by an early explorer. I hear that the wire is still intact, it just didn't stay attached to the tie-off points. It is now a hazard, like the rolls of barbed wire on a battlefield.
