| Research Abstract |
We developed a novel differentiation technique for most textile fibers using terahertz (THz) transmittance spectroscopy. As demonstrations, several kinds of plant-derived fibers, animal fibers, and artificial fibers were milled at 77K, and were examined by THz spectroscopy in the range from 0.5 to 10 THz. Absorption spectra of a majority of textile fibers are distinguishable by THz spectroscopy, even for fibers in the same category or species. The advantage of this technique is its sensitivity to the structural differences of the fibers, even if they consist largely of the same components. As an example, the THz spectra of cellulosic fibers in the category of plant-derived fibers and regenerated cellulose fibers showed an identifiable character.
