Synthetics include nylon, polypropylene
(silver rope), polyethylene (in both staple and monofilament construction) and
many described by their trade names (vinlon and kevlar). This type of rope when
new is very slippery and offers real risk if some of the traditional knots are
used. In addition friction can become a very serious wear factor for some
synthetics.
The “knots and lashings” we describe in this study have been used over a
decade or more in all types of construction and tie down work. When tied
correctly none have come undone under load or when the rope is loose.
Essentially, if a “loop” is needed in a rope it either has to be tied at the end
or along the rope. Accordingly, for reference purposes, we refer to the former
as end of line loops and the latter as mid line loops. Although these knots can
be used for natural fibre ropes, synthetic ropes specifically need these knots.
Bowlines, if left in an un-tensioned synthetic rope, have a tendency to come
loose. The double figure of eight will not. We are saying will not, not should
not. Enough of the nots let’s proceed to Knots.
We accept that, in addition to those we have listed, there are other different knots and lashings that will do the tasks required. However we have found those listed in this study are simple and the most effective.
