Dupioni Dupioni Dupioni (also referred to as Douppioni or Dupion) 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. It is similar to shantung, but slightly thicker, heavier, and with a greater slub (cross-wise irregularity) count. Dupioni is often woven with differing colors of threads scattered through the warp and weft. This technique gives the fabric an iridescent effect, similar to but not as pronounced as shot silk taffeta. Dupioni can be
Fire-retardant fabric Fire-retardant fabric Fire-retardant fabrics are textiles that are naturally more resistant to fire than others through chemical treatment or manufactured fireproof fibers. The term "fire-retardant" as applied to organic (i.e., containing carbon) materials, is intended to refer to "reduced" fire hazard, as all will burn under certain circumstances. The tests used specified in building codes, such as NFPA 701, are more correctly "flame resistance" tests, which test a fabric's ability to resist ignition with the flame size and duration in the test conditions. The result is a comparative test, which provides a measure of the material's resistance to propagating combustion
