What Temperature Should I Iron Viscose?
It is recommended to iron viscose at a low to medium temperature setting, preferably below 150°C (302°F), with steam if possible. Ironing at high temperatures can cause the fabric to shrink, distort, or even melt. It is always best to check the care label of the garment or fabric before ironing, as some blends of viscose with other fibers may have different ironing requirements.
