This article shows that TMA is an excellent technique to characterize the expansion and shrinking behavior of fibers. Effects originating in the manufacturing process and subsequent processing steps can be detected and decribed. The TMA curves allow properties such as the glass transition temperature, the degree of shrinking and the melting temperature to be determined. Values of the expansion coefficients, Young's modulus and the force of contraction can be calculated and displayed as a function of temperature. The measuring system can also be used to condition fibers at different temperatures, or under different tensile forces or gas atmospheres.
