Given rayon’s environmental and social impacts, you may think it’s a fabric to steer clear of. But, with technology progressing, new rayon fabrics are developed using sustainable processes and practices that include: 

Most dyeing factories do not have steaming equipment and directly press water to set. When the temperature is below 10 degrees (winter), creases are easy to appear on the fabric. The fabric will be set after being relaxed in the steam box, which will achieve satisfactory results. The heat setting temperature is preferably between 185 and 190℃, and the setting time is 45 to 60 seconds. If the setting temperature is too high, the fabric will turn yellow.
