This book presents a comparative study of twin types of banknotes ـــــ paper and polymer. In undertaking this study, the author has made several experiments. The detail is provided in twenty-six chapters.
Chapter one provides an introductory discourse. The study explains the difference between paper as piece of cotton and polymer. Chapter two deals with the pulping process from the trees and transforming the wood into a fibrous mass. Third chapter discusses the manufacturing process. Chapter four demonstrates the initial commencement of polymer processing. It explains that banknotes are made of dual axis polypropylene. Chapter five presents the security features in banknotes through four components ـــــ the substrate features, the ink features the design features, and security in machine readable features. Chapter six reviews the subject of hygiene. It discusses the possibility of germs and microorganisms to accumulate on the paper notes. Polymer banknotes are cleaner because of their non-porous basic material. Chapter seven discusses the environmental impacts of polymeric banknotes. The disposal of Polymer banknotes causes no environmental problems, and they can be easily recycled into other useful plastic products. Chapter eight provides a presentation of chemical and physical analysis of papers and polymer banknotes. Raw material, composition and weight are included in the presentation. Chapter nine reviews the mechanical properties of paper and polymer banknotes in terms of multiple factors ـــــ tensile strength and breaking length, burst strength, tear resistance and tear initiation, and folding endurance.
Chapter ten deals with aging of banknotes. This is done through the study of the effect of temperature. Chapter eleven offers a thermal analysis of banknotes against temperature effects. In chapters twelve through twenty-six, a group of tests on two types of banknotes are conducted and their results were compared.
