b. Semi-Synthetic Fiber
c. Natural Fiber
d. Artificial Fiber
Answer  Explanation 

ANSWER: Semi-Synthetic Fiber

Explanation:

  • Rayon is a manufactured regenerated cellulose fiber.
  • It is made from purified cellulose, primarily from 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 synthetic fibers of nearly pure cellulose.
  • Because rayon is manufactured from naturally occurring polymers, it is considered a semi-synthetic fiber.
  • Specific types of rayon include viscose, modal and lyocell, each of which differs in manufacturing process and properties of the finished product.
