Viscose fabric or Viscose Rayon has a silk-like aesthetic with superb drape and feel and retains its rich brilliant colours so ideal as a curtain fabric or drapes. Viscose material with its cellulosic base contributes many properties similar to those of cotton or other natural cellulosic fibres. Rayon is moisture absorbent (more so than cotton), breathable, comfortable to wear, and easily dyed in vivid colours. It does not build up static electricity, nor will it pill unless the fabric is made from short, low-twist yarns. Rayon is comfortable, soft to the skin, and has moderate dry strength and abrasion resistance. Like other cellulosic fibres, it is not resilient, which means that it will wrinkle. Rayon withstands ironing temperatures slightly less than those of cotton. It may be attacked by silverfish and termites, but generally resists insect damage. It will mildew, but that generally is not a problem. One of rayon's strengths is its versatility and ability to blend easily with many fibre, sometimes to reduce cost, other times for lustre, softness, or absorbency and resulting comfort. Rayon has moderate resistance to acids and alkalis and generally the fibre itself is not damaged by bleaches; however, dyes used in the fabric may experience colour change. As a cellulosic fibre, rayon will burn, but flame retardant finishes can be applied.
