Viscose rayon fabric as popularly known is from viscose (cellulose xanthate) fibers. It is cellulose ester obtained by treating cellulose with caustic soda. The International Organisation for standardisation prefers the name viscose to rayon (regenerated cellulose). The name viscose was derived from the word viscous, which describes the liquid state of the spinning solution. |

In burning test, rayon mostly resembles cotton. It ignites rapidly, sometimes faster than cotton, burning with a large bright flame.
Care
Usually require dry cleaning for better result. High wet modulus, high wet strength and polynosic rayons, will normally machine wash and tumble dry satisfactorily. Avoid spilling acid and alkalis on viscose.
The low wet strength of untreated viscose is likely to cause shrinkage and loss of body if fabrics made of these fibers are machine washed or hand washed. Viscose yarn is moisture sensitive, so it should be protected from moisture.
It is one of the most misunderstood fiber. It is nor a natural fiber and neither a synthetic. It is a fiber formed by regenerating natural materials into a usable form.
