Abstract

The present disclosure relates to patterned, flame resistant fabrics and methods of making them. Generally speaking, the fabrics comprise a plurality of high tenacity, flame resistant fibers, and a plurality of cellulosic fibers containing a flame retardant compound, and at least one color which is printed on the fabric to form the pattern. In a preferred embodiment, the flame resistant fibers are para-aramid fibers and the cellulosic fibers are rayon fibers to yield a strong, flame resistant fabric.
