Smart textiles are intelligent garments with functionality integrated directly into the fabric. The key to stable operation is the electrical circuitry.
HC High Conductive threads for industrial embroidery machines.
In smart textiles, the use of hard traditional materials for electronic circuitry is often problematic as they are not flexible enough, tend to crack, are not washable and don’t feel comfortable on the skin.
Cutting edge manufacturing technology transforms Statex’s well known Shieldex yarn into a state-of-the-art embroidery thread with unrivalled machining performance. This polyamide thread with durable 100% silver plating around every single filament offers high conductivity and optimised contact points and circuit paths. Also suitable as sewing thread, it is the smart choice for innovative textiles in sportswear, workwear, medical, fashion, automotive, home textiles and many other e-textile applications.
HC threads can be hidden between two layers of fabric or smooth enough to be directly on the skin. This flexible yarn has been specially developed for all kinds of electronic application and can be used to create circuitry for sensors, actuators, heating, sound transmission or to attach LED sequins.
Heavy fully silver-plated dtex 235×2 embroidery thread with resistance < 100 Ohm/m. Suitable for robust circuitry and all applications where a very low resistance is required. Available on 1000m cones, recommended needle size 100/16 needles.

HOW TO CHANGE THE RESISTANCE OF TEXTILE CIRCUITRY
A changeable resistance is important for controlling the conductivity of textile wiring. This can be achieved by varying the number of stitches or the amount of thread used. The resistance drops when using more conductive material. In embroidery, this can be done by stitching several running stitches or by combining running stitches with an overlaid satin stitch. The use of conductive bobbin thread in combination with several running stitches can reduce the nominal resistance of the individual thread by up to 90%. The length of the textile circuitry, thread tension and stitch density also influence the resistance. For this reason, it is highly recommended to always run your own tests and measurements to find the perfect solution for your application.
