Regenerated fiber is a type of textile made from natural materials that have been chemically processed to create fibers. Common sources include cellulose from wood pulp or cotton. The process involves dissolving the natural material and then re-spinning it into fibers, which can be woven or knitted into fabrics. Examples of regenerated fibers include viscose, lyocell, and modal. These fibers are often valued for their softness, breathability, and ability to mimic the feel of silk or cotton. Regenerated fibers are also considered more sustainable than synthetic fibers, as they originate from renewable resources.
