Loading... Please wait...Dupioni Silk (meaning double) is produced when two or more silkworms spin their cocoons closely together. These slightly tangled cocoons produce filament that is rough & uneven and is woven to create a fabric with pronounced irregular slubs at random intervals. It has a nice, crisp hand, and is often cross-woven with a different color for a shimmering effect. Silk Dupioni is an upgraded fabric choice.
