Thread size confusion... 30/3???

[MtlBiker]

I've only been sewing for a few months so obviously the stuff I don't know would fill a book but I'm really confused about the different thread size specs...

For a little project I want to do, I need a thread that's pretty resistant to high heat... won't be flames, but high heat.  I understand nylon and polyester wouldn't be good choices.  So I've found a Canadian supplier who lists Nomex thread, but I don't understand the spec they quote:

30/3, with 3,000m per spool.

I'm familiar with v69, 92 and 138.  But what's 30/3?  Is it comparable size/strength as v69, v92 or 138?

Thanks for any help.

Don't quote me,  but may be a 3 stand thread.

The thread size 30 / 3 is shorthand for 30 / 1x3 which is the same size as V92, Tex 90, Tkt 30 thread. It is constructed with 3 plies twisted together.

Thank you Keith!  There hadn't been any replies here to my post but you helped me figure this out by private email a month ago.

Cheers!
