Slow down!. Speed and fancy thread don't mix!
Yenmet thread is strong and smooth running.
Yenmet is made with a nylon core, wrapped (not twisted) with metallic and coated with polyester.
Treat this thread like any other polyester thread (like Isacord)
Yenmet Metallic Thread is specifically designed for today's high speed industrial embroidery machines.
Yenmet metallic thread has been developed to run similar to regular embroidery threads at high production speeds without breaking, tangling, or shredding Yenmet like an 80/12 embroidery titanium needle.
Another tip for using the metallic thread is to slow down the speed of the embroidery machine. It may also be necessary to reduce the needle tension. Stitch out a sample first, before adjusting the tension. Also try placing a thread net over the thread spool, so it stops the thread from sliding and tangling when it is pulled from the spool.
