Silk  Polymer= protein  Monomer= amino acids (but less of a variety than wool) 3. Cotton  Polymer= cellulose (plant)  Monomer= glucose 4. Linen  Polymer= cellulose (flax plant)  Longer chains than cotton which makes it brittle  Monomer= glucose

1. Polyamides —linked by amino group Example: Nylon Stronger and more chemically inert than natural fibers Image from:

1. Polyamides—linked by amino group Example: Nylon Stronger and more chemically inert than natural fibers 2. Polyesters —linked by ester group Stronger linkage than polyamides Linkage can be linear (flexible) or cross- linked (rigid) Image from:

Polyesters—lined by ester group Stronger linkage than polyamides Linkage can be linear (flexible) or cross-linked (rigid ) 3. Spandex—structurally similar to polyamide Made of segments of polyurethane connected to long segments of polyesters Resulting spandex can stretch up to 600 times and recover original strength /
