why is rayon called as semisynthetic fibre?
The synthetic fibers are those which are made by improving naturally occurring animal and plant fibers,
Rayon was the first artificial (man-made) fibre. It is a manufactured from cellulose fibre. It is produced from naturally occurring polymers it is neither a truly synthetic fibre nor natural fiber.
Thus it is a semi synthetic fiber.
Hope it helps.
Rayon is a manufactured regenerated cellulose fiber. Because it is produced from naturally occurring polymers, it is neither a truly synthetic fiber nor a natural fiber; it is a semi-synthetic fiber. Rayon is known by the names viscose rayon and art silk in the textile industry. It usually has a high lustre quality giving it a bright sheen.
