One of the key properties of Rayon Viscose Chiffon fabric is its lightweight nature. It is incredibly soft to the touch and has a smooth, luxurious feel. The fabric drapes beautifully due to its fine threads, creating an elegant and ethereal look. Rayon fibers are highly breathable, making chiffon fabric ideal for warmer climates or seasons. Rayon viscose is a synthetic fiber derived from wood pulp, making it a semi-synthetic fabric. To create Rayon Viscose Chiffon fabric, cellulose fibers from wood pulp are dissolved in a chemical solution and then extruded through fine holes called spinnerets. The resulting viscose fibers are processed and spun into yarns. These yarns are then woven or knitted into chiffon fabric using various techniques. The 45S specification refers to the fineness of the yarn used, with 45S being finer and more delicate.
