Paper has been widely used as convenient vehicle for the acquisition, storage and dissemination of human knowledge. Functional papers are used in specific purpose such as: water proof paper, carbon paper, electrical paper, friction glazed paper, magnetic recording paper or tape, marbled paper, mold and insect resistance paper, tracing and oiled papers, wax coated paper etc. Unfortunately, and depending upon natural and environmental conditions, paper, especially that prepared from non-wood fibrous materials (Agro-fibers) is subject to attack from several sources known to damage paper and cause deterioration in its properties. The agents which cause deterioration in paper are broadly classified as biological agents, physical agents and chemical agents. Functional paper must have durability (permanence paper). Most permanence papers are made from cotton or mixed with linter fibers for obtaining strength and durability. In this book I will focus on presenting approaches for enhancing the durability of paper sheets and accept it valuable properties, e.g., enhancing the forgery test for reappearing the writing in burnt documents.
