Natural polymers. Polymers are very common in nature; some of the most widespread naturally occurring substances are polymers. Starch and cellulose are examples. Green plants have the ability to take the simple sugar known as glucose and make very long chains containing many glucose units.atural polymers.

Polyamide occurs both naturally and artificially and is used in the making of a variety of materials. Naturally occurring polyamides are wool and silk which are nothing but proteins, while artificially manufactured polyamides are nylon, sodium poly(asparate) and aramids.As far as Polyamide Fabric is concerned, it is generally sold as nylon in all parts of the world.ylon is light-weight, but at the same time, a strong fabric. The fibers that are used to make nylon are smooth and non-absorbent, meaning anything that is made up of nylon dries up easily and quickly. Nylon is also dirt resistant and is not affected by any chemicals or sweat.
