Rayon Thread
Rayon embroidery threads are currently the most popular threads used in embroidery machinery. They perform consistently well in high-speed embroidery machinery with very little breaking or fraying. Rayon is a high sheen thread, and often used as a lower cost alternative to silk threads.

Most Rayon embroidery threads are available in 40wt, though 30wt can be found without effort. A wide range of colors and shades are available, including variegated colors.

Though some brands can be, rayon embroidery threads are not generally colorfast. It is best to avoid using any bleaching agents, including those made for colors.

Stitches sewn with rayon threads are very smooth and consistent, leading to a higher quality embroidery project.

Rayon threads do deteriorate over time, so attention should be paid to how it is stored. In low humidity regions, rayon threads can be stored in the refrigerator to extend thread life for a long as possible.
