Description: This is about 360 yards of conductive thread spun from stainless steel fiber and wound on a spool. You can use it as a creative way to connect various electronics onto clothing projects. This large spool is a great way to get into wearable electronics without a large upfront cost and a large enough quantity to not be afraid of making a few mistakes. 

What sets this thread apart from the other conductive thread that we carry is the fact that it's actually spun from stainless steel fibers (as opposed to plated silver) and doesn't have a Nylon core. This means that while it may not be easy to solder to, because it's stainless, it also won't burn up when you touch it with a soldering iron. Also, it's somewhat 'hairy' and can be slightly more difficult to work with in close, fine conditions than the other thread. Our resident E-Textiles expert suggests waxing the thread for hand sewing, as this should take care of any 'hairy thread' issues. Since waxing is impractical in machine sewing applications, avoid sewing close connections by machine as the 'hairs' could potentially short across small distances.

  • will this thread heat up so that it could be used with thermochromic paints?

    • Anything heats up if you put enough current through it (as long as it is not at near absolute zero temperatures). The question is how much current is required to get it to heat up to a noticeable value. So what the resistance is would be a good question that I would also wonder. Are there any data sheets on this?

      • The resistance is 28Ohms/ft. If you double up the thread, that cuts the resistance in half.

        • Simply doubling up the thread won’t work. 2X the tread means more current needed to heat up the thread, I’m not sure how much more current though.

  • Is there a data sheet for this? I’m interested in the current limit.

  • I wonder if this would work for creating lighting stikes if you tie one end to your model rocket?
