my washing line is a metal twist cable with a smooth plastic coating.
it will kink, after much effort,
and all knots I've tried in it simply spontaneously undo themselves.
I guess it's more like fishing line that's 5mm thick.
all I wanna do is make a permanent loop in one end to hang over a hook.
I'm not sure what you mean by "it will kink, after much effort",
but guess that you're saying that the line is INflexible, but can
be made to bend (and, yes, monofilament fishline can be like
this --and once so bent, can have "memory" of that bend and
not want to straighten, completely).
The angler's
"surgeon's knot", which we might otherwise
call a
"double overhand / strangle loop", should be one
that can be forced into the line and then stay tied. Similar
would be the
grapevine loop. (The s.l. and g.l. both use
strangle knots : the former is made by doubling the line
and then tying the knot (so one side will have the loop end
of the bight for your eye); the latter is, you could say, a
slipped
strangle with the tail tied off to its SPart with
the same knot, and those pull together, abutting, when
the is loaded.
But, as Knot4U suggests, knotting might not be the best
solution. I've not seen what he points to, but seizing an
eye into your line should be possible, using some suitably
fine & strong material, and maybe using those same
strangle knots for the binding (with multiple wraps,
not the basic one overwrap). This would probably be the
neatest, most material-efficient solution.
