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
Fabric softener provide the advantage of increased ability of smaller particles to penetrate into the fibers. Manufacturers often use a mixture of cationic and non-ionic surfactants as an emulsifier. Another approach is a polymeric network, an emulsion polymer. In addition to fabric softening chemicals, fabric softeners may include acids or bases to maintain optimal pH for absorption, silicone-based anti-foaming agents, emulsion stabilizers, fragrances, and colors. Rinse-cycle softeners usually contain cationic surfactants of the quaternary ammonium type as the main active ingredient. Cationic surfactants adhere well to natural fibers (wool, cotton), but less so to synthetic fibers. Cationic softeners are incompatible with anionic
