An area rug created on a large mechanical loom, strung with a jute warp and woven using nylon, polypropylene, or wool. Computer-operated machines produce a number of styles in various sizes from a predetermined set of colors. More than 40 shades can be achieved in a single area rug, although they commonly include 6 to 12 colors. Machine-made rugs are high in design definition, and though they are not hand-woven, the mechanistic appearance of ornamentation is not obvious.
