Abstract

The IR spectroscopy is a versatile analytical method to identify chemical compounds and analyze their composition. This spectroscopic method is fast and provides a non-destructive analysis of the investigated materials. By this, the IR spectroscopy is an excellent tool for investigation of consumer textile products which are often produced from different types of synthetic and natural fibers. The current overview supports a broad overview of IR spectra from textile products from mono-materials and fiber blends. Further, a view on selected special and high-performance fibers is provided. The determined IR spectra are structurally discussed under consideration of the related chemical structures of polymers building up the fiber materials. The advantages but also the limits of this method for analysis of fiber materials, commercial fiber-based products and special fibers are presented. Overall, valuable spectroscopic data on polymers and fiber materials are supported. These data are helpful for people working in quality control, fiber identification and analytics. Finally, this current overview paper, is a useful educational tool to teach the composition of fiber materials, the chemical nature of fibers and related analytical methods.
