Figure 1: Three common polymer structures. The linear, branched, and network architectures are represented (from top), respectively, by high-density polyethylene (HDPE), low-density polyethylene (LDPE), and phenol formaldehyde (PF). The chemical structure and molecular structure of highlighted regions are also shown. A step-by-step diagram shows the wet spinning process for polymeric fibers, beginning with a polymer solution pumped through a filter into a spin bath, forming fibers via a spinnerette. The fibers move through stages labeled coagulating, stretching, washing in a wash tank, applying fiber finish, and drying on heated drum rolls. The finished fibers are either wound into a take-up package or cut into pieces. Arrows and labels indicate solvent diffusion and each stage of the process.
