Answer:
Hey Mate Here is your answer !
Explanation:
Rayon is a manufactured fiber made from natural sources such as wood and agricultural products that are regenerated as cellulose fiber. The many types and grades of rayon can imitate the feel and texture of natural fibers such as silk, wool, cotton, and linen.
Rayon is not considered to be synthetic.[1] Technically, the term synthetic fiber is reserved for fully synthetic fibers. In manufacturing terms, rayon is classified as "a fiber formed by regenerating natural materials into a usable form".[2] Specific types of rayon include viscose, modal and lyocell, each of which differs in the manufacturing process and the properties of the finished product.
The raw material for viscose is primarily wood pulp, which is chemically converted into a soluble compound. It is then dissolved and forced through a spinneret to produce filaments which are chemically solidified, resulting in fibers of nearly pure cellulose.[3] Unless the chemicals are handled carefully, workers can be seriously harmed by the carbon disulfide used to manufacture most rayon.[4][5]
To safeguard the workers from the hazards of the chemicals, new technologies are now applied by the leading manufacturers of viscose to efficiently capture the emissions and recover and recycle the carbon disulfide.[citation needed] These technologies have significantly reduced the risks and have addressed the safety concern related to exposing workers to chemicals.
