Question

what about the synthetic fabres and plastics​

Answer 1

Answer:

Polyester (Poly + ester) is made up of the repeating units of a chemical known as an ester. Plastic is also a sort of polymer like the synthetic fiber. ... There are some plastics, which when molded once, cannot be softened by heating; therefore, these are known as thermosetting plastics. E.g. Bakelite and melamine.
