ABSTRACT

This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book begins with polymer characterization methods. It discusses the importance of structural characterization of fibers and textiles using scanning electron microscopic techniques. The book focuses on the specifics of sample preparation and microscope operating conditions. It also focuses on analytical pyrolysis as a technique to identify and detects small changes in polymers, fibers and other textile auxiliaries. The book presents the scientific basis and application of conventional liquid chromatography for dye identification, separation and purification. It draws on characterization of durable-press finishes for cellulosic textiles using chromatographic and spectrophotometric methods. The book describes a technique based on the principles of gel-permeation chromatography. It provides an extensive background in basic colorimetry and describes the color measuring systems, as well as the developments in color measuring instruments. The book deals with characterization of chemical barrier performance of textile systems.
