Dupion Silk, also known as Dupioni or Douppioni Silk, is created with the threads from two different silkworms, also called double palace silk. It has inherent lumps or silk knots within the yarn fabric. It is one of the purest silks in its natural form and one of the classiest and most luxurious silk fabrics available. Dupioni is a plain weave crisp type of silk fabric, produced by using fine thread in the warp and uneven thread reeled from two or more entangled cocoons in the weft. This creates tightly woven yardage with a highly lustrous surface.
