"From Filament to Fabric Silk seems to have played an important role in the development of loom and weaving technology. Traces of primitive looms and woven fabrics are found in excavations in Egypt, China, India and Peru (2500 to 400 BC)...The silk weavers of China innovated the use of heddle and draw loom, a revolutionary development over the primitive tribal loom. India invented a foot tradle for silk weaving, a technical innovation over the ancient loom."
