In the process of rope production, the fibres are mechanically doubled,
twisted and braided in several stages. In this way the fibres finally
attain a condition of mechanically induced stress. A long-term
storage leads to retardation and relaxation. This means that stress
in macromolecules is “relieving”. This phenomenon is not harmful,
on the contrary it is connected with an improvement of dynamic
properties. Research works showed that the results of tests of dynamic
performance of ropes that had been (optimally) stored for several
years were often better than values measured immediately after
production.
