Other Properties

Paper fiber type: non-woody/bast. Using transmitted light microscopy, bast fibers are identified by their prominent nodes, and long fibers. Width of the lumen varies with species. Appearance with Graff "C" stain: varies with species, but typically pinkish red due to high Alpha cellulose, nodes may stain red. Average dimensions of fibers: varies with species. Common pulping method: Soda. For specific paper fiber properties see: Flax, Jute, Hemp, Ramie, Abaca, and Sisal.
