A plain weave, rather lustrous and crisp silk fabric with pronounced irregular ribs formed by slubbed yarns. The slubs are formed by the spinning of silk from a double (from which the name derives) silkworm cocoon, which can’t be unwound evenly in the reeling process, leaving thicker spots in the filaments. The slubbed ribs are usually horizontal (in the weft) but may also be vertical (in the warp). Doupioni silk is naturally an ecru shade but is often dyed in bright and/or iridescent colors.
As compared to its close relative shantung, doupioni silk is heavier in weight, with more pronounced slubs.
Uses: Blouses, dresses, skirts, suits, neckties
