Construction

Machine made rugs are produced by electrically powered looms that are often controlled by computers. A machine made rug is constructed very differently than a handmade rug. For instance, some machine made rug will have a very uniform appearance. They are often made with synthetic materials such as polypropylene, polyolefin, a blend of synthetic and natural materials or all natural materials. Most machine made rugs will have a fake fringe attached to the ends, whereas in a hand-knotted rug, the fringe is actually a part of the rug and is made of the warp threads that run the length of the rug. These warp threads are tied at either end so the rug will not unravel thus creating the fringes. In machine made rugs the binding is machine stitched unlike in most handmade rugs where the edges are part of the rug made of warps and wefts sometimes this is reinforced with threads known as binding or selvage.
