Question

What characteristics would you use to identify a synthetic fiber versus an animal fiber

Answer 1

Synthetic fibers are usually composed of very smooth filaments. Animal fibers can be identified using the criteria described in Chapter 5, “Hair.” Synthetic fibers are extruded when they are hot; this means that they are forced out of a spinneret, which is a nozzle like a showerhead; and then they are wound or woven.
