A wearable article made from a nonwoven fabric that includes a plurality of coated fibers. The coated fibers have an exterior surface and a coating composition on at least a portion of the exterior surface. The coating composition includes an aminofunctionalized silane and a dialdehyde, where the weight percent of the dialdehyde in the coating composition is greater than the weight percent of the silane in the coating composition. The wearable article can be a wrap, brace, support, compression hosiery, bandage or compress. When worn, the wearable article is initially flexible but becomes rigid and stiff when the coated fibers experience a sudden force or impact. The wearable article does not include a fluid.
