Some of the main properties of viscose fiber are a silk-like aesthetic, excellent drape and rich, vibrant colors. Additionally, viscose fiber is moisture absorbent, comfortable to wear and is easily dyed in most colors.
The cellulosic base of viscose fiber is very similar to that of cotton; it is breathable, doesn't build up static electricity, and rarely pulls. Also, it is actually better at absorbing moisture than cotton. Viscose, or viscose rayon, is soft on the skin and has a medium dry strength and abrasion resistance. One downside to viscose is that it is not resilient, meaning it tends to wrinkle easily.
Viscose typically can withstand ironing temperatures, although slightly less than cotton, and it is very versatile as it blends easily with other fibers. It does an average job of resisting acids and alkalis when compared to other fibers and does not get damaged by bleaches. Because viscose is a cellulosic fiber, it does burn easily. In fact, it's so easy to burn that the Flammable Fabrics Act was inspired by it, as rayon sweaters used to catch fire commonly in the 1950s.
Viscose fiber can mildew, although it is not common. It is also commonly targeted by silverfish and termites, but most times resists insect damage.
