Braided nylon fly lines

#1

Post by kevinhaney1 »

I've acquired a bunch of old braided nylon fly lines. Not knowing their history, I assume they were made to look like silk lines during the transition from silk to nylon in the 1950s? Since they look very much like silk lines, is there an easy way to tell the difference? And if one wanted to use them, do they require a line dressing to float like silk? And lastly, with nylon that old, would it be wise to use them at all?

Hi,
I'm no expert but I think there is a burn test. If you burn silk it burns like hair whereas nylon makes a hard plastic blob on the end. I believe dressing helps them float, but not sure if it is necessary.

Burn test is a good way to tell, you can dress them, they are typically "lighter" or less dense than silk of the same diameters.
You could use them, but I would not use them on "good fish".
Just my opinions.

The two greatest dangers to nylon, in order of significance, are ultraviolet light (UV) and heat. If they have been kept indoors in a moderately cool environment, they Could Be "good as new". You can use the same test that is used on old silk lines: simply pull off lengths convenient for you to pull as hard as you can between your hands "hand over hand" until you have pulled the entire line. If they have been weakened by either, they will break at the weakened spots. Think; Monofilament leaders, and you should be OK. As previously noted, the "burn test" is the simplest way to differentiate. Burned silk leaves ash, burned nylon a "plastic" ball.

Thanks for all of the information everyone. The one question I still have is do they need dressing to float?

I have used them, refinished them and yes you do need to dress them. As as stated burning is the easiest way to determine the difference. They fish very well, though they vary a quite a bit in specifications, as far as weight goes. Which is similar to the difference in silk lines. If you want to refinish them you treat them the same as silk.

So you really need to coat them with varnish? It just sounds like varnish and nylon would not mix well.

No, the lines just need to be treated (dressed) with a floatant such as Mucilin to make them buoyant. That is if the finish is still good.

Do nylon lines have a finish on them? If so what is it?

f you need to refinish the line you would use the same formula for silk, "Over My Waders" formula. To float the line while fishing you need to apply a floatant, Otter Butter or Red Muclin.

So what is the time period during which these braided nylon lines were made? And how do you tell if it needs a new coat of varnish rather than just dressing it with a floatant and going fishing?
