Raw silk is a silk fabric with linen-like plain weave and slightly nubby texture. The fibers are woven before any finishing processing is done, such as de-gumming, dyeing, breaking, steaming, pressing and lustering This creates a slightly nubby fabric with random flecks in a natural, off-white color. It has a somewhat rough texture and a gentle drape. The dyes disperses in a more random fashion that regular processed silks and creates a mottled effect.
