What is the different between cotton and polyester, chemistry wise

Answer 1

Cotton is a natural fiber derived from the seed of the cotton plant, while polyester is a synthetic fiber made from petrochemicals.

Chemically, cotton is composed of cellulose, a complex carbohydrate made up of thousands of glucose molecules bonded together. Polyester, on the other hand, is composed of a long chain of synthetic polymers derived from petroleum-based chemicals.

In terms of properties, cotton is known for its softness, breathability, and ability to absorb moisture. It is also biodegradable and more environmentally friendly compared to polyester. Polyester, on the other hand, is more durable, wrinkle-resistant, and has better resistance to fading and shrinking compared to cotton. It is also less prone to damage from mold, mildew, and pests.

In summary, the main difference between cotton and polyester chemistry-wise is that cotton is a natural fiber composed of cellulose, while polyester is a synthetic fiber made of petrochemical-based polymers.
