Abstract

In this chapter the basics of thermogravimetric analysis (TGA) are explained, and the use TGA in research and characterization of fibers is shown. It is explained how to use TGA for measuring the losses of low-molecular-mass materials during temperature increase and how to characterize thermal and thermo-oxidative stability of organic polymer–based fibers. The differences between thermal stabilities of bulk polymers and fibers are illustrated. It is demonstrated how to use TGA for determining the effects of crystallinity and molecular orientation on the thermal stability of fibers. Examples are given to describe the effect of flame retardation on thermal stability and various chemical treatments on thermal and thermo-oxidative stability of natural fibers.
