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
Waterproof fabric some garments made from fabrics that exceed 20 000 mm have leaked through zips, hoods, and seams. Fabric head ratings do not totally specify water resistance of a garment, as it does not test closures such as zips. In addition, the breathability of nearly all waterproof/breathable fabrics is very dependent upon weather conditions, especially temperature, humidity and wind. Fabric construction which directs water away from the body, rather than membranes, coatings or laminates, can be used to keep the wearer dry. This means that perspiration can be moved away from the body more effectively, as both liquid water and water
