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.

Whilst a common application of tension fabric buildings is for temporary use, they are not exempt from regulatory requirements including compliance with building
