Yes, modal fabric blends are machine washable and dryable. However, it is important to follow the care instructions for the most delicate fibers in order to keep your garment looking its best. Ironing techniques should be used on woven fabrics while knitted varieties usually resist wrinkling.
Using a mesh washing bag with a gentle cycle setting is recommended when caring for these garments along with avoiding chlorine bleach and using oxygen bleach instead if needed to brighten colors. Fabric softeners can be used but may cause color fading over time so pre-treating stains is highly encouraged as well as regular garment maintenance such as removing clothing from washer and shaking out wrinkles before drying at low or medium-high temperatures depending on desired results.
