Description

A generic name for a modified rayon fiber that has high tenacity and high wet modulus. Modal fibers were initially developed in the 1930s for industrial uses in tires, conveyor belts and hose pipes. Changes in the rayon processing, such as the spin conditions, chemical solutions, and stretching sequences, produced rayon fibers with increased crystallinity, and thus, greater strength. Additional developments in Japan in 1951 by S. Tachikawa led to the production of a modal fiber with high wet modulus called polynosic. Modal fibers are dimensionally stable and do not shrink or get pulled out of shape when wet like many rayons. They are also wear resistant and strong while maintaining a soft, silky feel. Modal fibers have found a wide variety of uses in clothing, outerwear and household furnishings. They are often blended with Cotton, Wool, or synthetic fibers.
