Modal is a manufactured cellulose fiber that was first developed in Japan in 1951. As a fiber in the rayon family, it is known for being stronger and more stable than other types of rayon fiber. Modal is manufactured in a modified solvent spun process that is a bit different than the viscose process. In general, manufactured cellulose fiber is less durable than synthetic fiber. However, manufactured cellulose fiber has the potential to be engineered as a performance fiber depending on the application. Modal is commonly used in the apparel industry. It is also often blended with synthetic fiber to increase the strength and keep the luxe feel for use as upholstery, wallcoverings, and carpet applications.
