Finishes and coatings are often applied to textile mate rials in order to alter their physical characteristics by changing the nature of the surface and, therefore, the interaction between elements of the structure. Sometimes these have adverse effects such as, for example, a loss in tearing strength. Various microscopical techniques are described and illustrated which can be useful in examining the distribution of the added material, its penetration into the structure, and the nature of the interaction which exists between the finish or coating and the fibrous substrate, as well as between fibrous elements within the structure.
