Polymers are materials comprised of long molecular chains. Most polymers are carbon based and have relatively low melting points. Polymers have a very wide range of properties which allow for their extensive use in society. The image is of Styrofoam packaging peanut. There are many SEM-image sites on the Internet.
Synthetic fabrics are man-made copies of natural fabrics.
