Viscose is a cellulose fiber from purified wood pulp which was chemically treated and extruded through a spinneret. It was developed in Britain in the beginning of the twentieth century and was originally used in filament form for hosiery, satin linings, and dresswear. Now it is generally used as spun staple in surgical dressings, knitted underwear, bedsheets, dress fabrics, etc. -- AATA
