This is Kitronik's very own Electro-Fashion® branded Conductive Thread and we think it is among the best conductive thread available. It is perfect for hand sewing and can also be used on the bottom bobbin of a sewing machine (this will require the thread to be wound on to the smaller bottom bobbin first).
Conductive thread can be used like conventional sewing yarn, however it electrically conducts allowing electronics to be integrated into textiles. This makes it ideal for use in a range of e-textile applications.
The thread is nano plated with silver to make it conductive. The conductive thread has a low resistance of approximately 40 Ohms per metre. This allows LEDs to be powered over quite large distances. Resistance does not vary significantly from one length of thread to the next, so you should be able to use this thread without concern for "dead" sections.
The conductive thread has a breaking strain of around 9.3 pounds (4.2 kilos). It comprises roughly 96 individual filaments, each coated with a micron-thick layer of natural silver. This plating of the yarn is done in Europe to ensure as high a quality finish as possible. In construction, 16 of these filaments are wound together to form an initial twist; two of these twists are then twisted together, and finally three of these twists are combined to form the finished thread. The conductive thread is approximately 18 denier. It is heavier than a regular sewing thread, but not as heavy as an upholstery thread. It can be sewn on most domestic sewing machines using either a regular needle or the next size up. This thread does not fray.
- No (or very low) fray.
- Conductivity = approximately 40Ω per metre.
- Count = 875 dTex.
- Strength 3000 cN.
- Elongation at break = 37%.
- Twist = 240Z-380S.
- 1 x Reel Electro-Fashion®, Conductive Thread, 50 yards / 45m.

Is this thread easily solderable?
Posted byon Thursday, 9 July 2015
You can't solder the conductive thread, it would just burn if you tried to solder it.
Hi, if I was to use this conductive thread and connect it to a small battery supply say about 900mAh or less...if I then touched the thread...would I get a small electric shock?
Posted byon Wednesday, 1 October 2014Hi, that depends on the voltage of the battery, but realistically the thread would burn up before allowing high enough voltages to give a shock.
Hi, I was wondering if you can sell your thread in any higher quantities than 50 yards? Also, would you be willing to send me a sample so that I can test the durability and heat resistance of your product, and compare it to the thread I am already using. Thank you for your time, I hope to hear back from you soon.
Posted byon Friday, 19 September 2014Hi, we may be able to sell it in higher quantities, it depends on how much you require. If you email me some details (how much you are looking for etc.) at firstname.lastname@example.org I will see what I can do.
Hello, what is the raw material of these yarns, it doesent look cotton to me, as mentioned above.
Posted byon Friday, 5 September 2014Hi, it is cotton. It's impregnated with silver though so it has a shiny grey appearance. It's still completely soft and feels like regular cotton.
If i used this thread to weave a wall hanging behind my bed with normal thread would it shield from EMF's from the walls electrics? How much of the conductive thread would i need to use for it to be affective in comparison to the other normal thread? thank you!
Posted byon Thursday, 19 June 2014It might work to some degree, aluminium foil would do the job better. Lower resistance and more homogeneous.
