Abstract

The physical, chemical, and mechanical properties of nonwovens governing their suitability for use depend on both the fabric's composition and structure. The composition in this context refers to the fibre content as well as any chemical binders, fillers, or finishes present on, or between the fibres in the fabric. The structure relates to the architecture and dimensional properties of the fabric, including the way in which the fibres are arranged. This chapter focuses on how nonwovens are tested and characterised and explores the influences of fabric structure on the physical and mechanical properties of fabrics. Some of the models that have been developed to describe the relationship between nonwoven fabric structure and physical properties are also introduced.
