Among the natural fibers are cellulose, the primary structural component of plants and bacterial cell walls, animal fiber such as wool and silk and biochemical fibers. Plant fibers are composed of cellulose or similar compounds while animal fibers are composed of protein.
Cellulose the most widespread organic molecule on earth, is the major component of plant cell walls.
The polymer Dacron is the example of synthetic condensation polymers, also known as step growth polymers

The answer is bis(2-hydroxyethyl) terephthalate.
The monomer used to prepare the artificial fiber Dacron is bis(2-hydroxyethyl) terephthalate. This monomer is synthesized due to the esterification between ethylene glycol and terephthalic acid using water as a byproduct. Another way to produce the monomer is by doing a transesterification between dimethyl terephthalate and ethylene glycol. In this case, methanol serves as the byproduct.
