Formerly known as man-made fiber, manufactured fiber is defined as “any fiber derived by a process of manufacture from any substance which, at any point in the manufacturing process, is not a fiber.” (Textile Fiber Products Identification Act, 1960)
Manufactured fibers include those regenerated from natural materials, synthetic fibers and inorganic fibers.
Inorganic fibers include ceramic, glass and metallic fibers.
