| Zusammenfassung: | Fiber analysis is an important part of object examination. One type of examination relies on staining reagents. The two iodine-based staining agents that are central to this thesis are zinc chloride iodine solution (a form of the Herzberg Stain) and Graff’s C-Stain, which are commonly used in paper analysis. Here, they are tested regarding their applicability for the identification of synthetic fibers. Natural (viscose, acetate fiber, triacetate) and synthetic polymers (polyester, polyamide 6, polyamide 6.6, polyacrylonitrile) are stained with the reagents and documented photographically and in writing after 2, 10 and 30 minutes respectively. It can be concluded that some distinctions are easier to make with C-Stain than with the zinc chloride iodine solution. Acetate fiber and triacetate can be distinguished after one to two days, as acetate fiber (partially) dissolves, while triacetate does not. Both fibers dissolve directly in zinc chloride iodine, which makes it impossible to distinguish between them. It also seems possible to distinguish between polyamide 6 and 6.6 when using C-stain, but further Tests are needed to define this distinction. In summary, the experiments confirmed the potential of the C-stain for synthetic fiber analysis and provide a starting point for more in-depth investigations. |
