MtlBiker Report post Posted March 17, 2021 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. Quote Share this post Link to post Share on other sites

kgg Report post Posted April 14, 2021 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. kgg Quote Share this post Link to post Share on other sites
