An overview of the design and structure of industrial fabrics addresses the definition of industrial fabrics, the difference between industrial fabric design and apparel fabric design, and product categorization. Industrial fabrics provide structure, support, insulation, and protection. They are engineered for specific physical characteristics, whereas apparel fabrics are designed for aesthetic characteristics. Categories of industrial fabrics include electronic fabrics for computers, telecommunications, and automotive parts; composite fabrics for airframe structures, duct work, and brake linings; reinforcement fabrics for asbestos replacement and protective clothing; and filter fabrics. An example of a fabric design process, including formulae, is given.
