No it is not.

Viscose rayon is a man-made fiber made from wood pulp though other materials may be used. It is basically modified cellulose. Viscose is very similar to cotton and silk. (Cotton is also made of cellulose). Viscose falls somewhere in between a natural fiber and a man-made one. The raw material for viscose is cellulose which is usually reacted with caustic soda and carbon disulfide. It is reformed as fibers by spinning this viscose solution in an acid bath. Viscose rayon has a silky appearance and feel, and also has the ability to breathe in a manner similar to cotton weaves.
due to hydrogen bonding no of molecular rearrangement in the structure is more than viscoce in viscose hydrogen bonds break up is more in terms of molecular arrangement so wet strength of cotton is higher than viscose fibre rajarahul28@gmail.com
(This fiber refers to Textile fiber)Natural fiber are naturally growing from Cotton plant.Man made fiber are polyster,rayon,viscose staple fiber. Its is a process of wood pulp chemically treated and processed to make a fiber equal to natural fiber with same qualities.viscose and cotton virtually have nodifference.But polyster have poor qualites compared to other in areas like thermal regain,moisture regain,softness,anti pilling,air premeabilty.
YES
Viscose is not considered a true natural fiber; it is a semi-synthetic fiber made from regenerated cellulose, primarily derived from wood pulp. The process of creating viscose involves chemically treating the cellulose to produce a fiber that resembles natural fibers like cotton or silk. While it originates from a natural source, the chemical processing involved means that it does not fit the strict definition of a natural fiber.
Staple
viscose dissolve in 40% sulphuric acid,but cotton in 70%.
Viscose and modal both are semi synthetic fibre, where the modal has more wet strength than viscose and have less shiny than viscose
Viscose is considered a semi-synthetic or man-made fiber. It is derived from natural sources such as wood pulp or cotton linters through a chemical process, resulting in a regenerated cellulose fiber.
Poly viscose is a blend of polyester and viscose (a type of rayon), providing a smooth and lightweight fabric. Poly cotton is a blend of polyester and cotton, offering a fabric that combines the durability of polyester with the breathability and comfort of cotton. Poly viscose is often used for drapey garments, while poly cotton is commonly used for casual clothing and workwear.
Viscose is a semi-synthetic fiber known for its softness, breathability, and drape. It has a similar feel to natural fibers like cotton and is often used in clothing, bed linens, and other textiles. Viscose is prone to wrinkling and can shrink when washed unless treated properly.
