What Type of Fabric Is Modal?

Modal is a type of rayon, or wood pulp-based textile material, made only from beech trees. Though modal and other types of rayon begin as plants, they are so heavily chemically processed that they cannot be listed as natural fibers.

Common modal items include undergarments, bedding and towels, as the fabric tends to resist shrinkage, be very absorbent and create fewer pills due to friction. Like cotton, 100 percent modal pieces can typically be machine washed, though full-strength bleach may weaken the fibers. To keep items looking crisp, they should be removed from the dryer while partially damp and ironed at a moderate temperature.
