A polymer is composed of many repeated units of monomers. What is polyester, cotton
and silk composed of?
Answers
Answer:
The main difference lies in the way these materials are produced. Silk is a naturally made animal protein fibre, whereas polyester is an industrially produced fibre made from petroleum, so it is essentially plastic. It can be mass-produced and is a lot cheaper than silk because of this.
Answer:
Polyester (polyethylene terephthalate) is derived from a chemical reaction involving petroleum, air, and water. This artificial fiber is comprised of purified terephthalic acid (PTA) and monotheluene glycol (MEG). Polyester is thermoplastic, meaning it can be melted and reformed
Cotton is made from the natural fibers of cotton plants, which are from the genus Gossypium.
The protein fiber of silk is composed mainly of fibroin and is produced by certain insect larvae to form cocoons.
