1. Microscopic analysis: This involves examining the physical characteristics of fibers under a microscope, such as color, shape, and texture.
2. Chemical composition analysis: This involves determining the chemical makeup of fibers using techniques such as infrared spectroscopy, mass spectrometry, and chromatography.
3. Thermal analysis: This involves studying the behavior of fibers when exposed to heat, such as their melting point and decomposition temperature.
4. Solubility tests: This involves testing the solubility of fibers in various solvents to help identify the type of fiber.
5. Dye analysis: This involves testing the fibers for the presence of dyes and pigments, which can help identify the type of fiber and potentially link it to a specific source.
6. Burn tests: This involves burning a small sample of the fiber and observing its behavior, such as flame color, odor, and residue left behind, to help identify the type of fiber.
7. Microspectrophotometry: This involves using a microscope equipped with a spectrophotometer to analyze the absorption and reflection of light by fibers, which can help identify the type of fiber and any dyes present.
