Why ropes do twist?

Ropes are manufactured un way they are neutral, but when retired from the reel or the twist we must manipulate them carefully in order  to avoid twists.  To get a proper neutral rope ready to use follow the procedure shown in the image.

Twists are mainly caused by the descenders and the rappeling techniques.The speleology  devices make the rope follow a pulley path in the same two-dimensions edge.

When the rope path is three-dimensional (as the  figure 8 belay device or a dynamic knot) then the rope twists.

It is advised to fully stretch the ropes from time to time in order to keep the rope in a neutral shape.

How a rope should be cleaned?

The washing frequency is entirely dependant upon the rope use. It can be washed either by hand or either in washing machine.  The soap must have a neutral PH, as well as the softener if added (it can help the fibers to work better, as in clothes). If washed in a machine spinningnmust be absolutely prevented, in order to avoid twists.

Ropes should dry  in a  shadowed  and dry place (direct sunlight exposing  harms the fibers) avoiding direct heat sources and drying machines.

Where ropes should be stored?

Proper rope storage is essential. Their fibers might lose their properties if they get in contact with cleaning products, oils or batteries.  Be sure to store your rope in a dark, cool and  dry place to keep it from getting damaged by sun, moist and chemicals.

Should we soak speleology or rope access ropes before using them?

All korda’s rope are factory pre-stretched, and then the firs soakning and drying cycle is done. Then it is unnecessary to damp them before their first use.  Considering the fact that the most important shrinking occurs with the first contact with water, Korda’s users receive rope that will shrink less than expected during their life span.

What is the difference between the Dana Speleology version rope (white) and the Canyoning version (colors)?

Both versions have exactly the same mechanic structure.  Nevertheless the Canyoning version have light colors to be easily spotted underwater and the TOTAL DRY finnish applied is stronger.  In this way the rope absorbs less water and consequently has a lower weight gain. This treatment also improves  the rope aging process and the wear caused by the constant soaking-drying.

How do we know if a rope is certified?

To know if a rope is certified we must check inside the rope, in the core.  All certified ropes are made with an internal tape informing the manufacturer, the certification type, (dynamic, semi-static) the year of manufacture and the material. This is not manadatory in dynamic ropes but recommended to identify the year of manufacture.color cinta interior

Following the Korda’s color chart you caneasily identify the year of manufacture of your rope.

 

First uses of the rope

A brand new rope requires a major care and attention during its use.

The fibers are new and relaxed, then more sensitive to friction that can generate cuts and burns. With use and aging (especially if in each session it gets wet and then dries up) the fibers compact, gain tension and improve their resistance to abrasion.

As a manufacturer, Korda’s strongly advises to be very careful during the first uses, particularly the first 4-5 occasions.
