Interpretive Summary: The examination of cotton fibers and common contaminants in fibers is presented. The examination was performed infrared microscope equipped with a high resolution array detector system. Infrared spectroscopy can provide us with information on the structure and quality of cotton fibers. In addition, small contaminants can be routinely identified given the spatial resolution provided by the array detector system. Examples of our ongoing efforts to use infrared maps of cotton fibers and common contaminants are presented.

Technical Abstract: The chemical imaging of cotton fibers and common contaminants in fibers is presented. Chemical imaging was performed with an infrared microscope equipped with a Focal-Plane Array (FPA) detector. Infrared spectroscopy can provide us with information on the structure and quality of cotton fibers. In addition, small contaminants can be routinely identified given the spatial resolution provided by the array detector system. Examples of our ongoing efforts to use FTIR imaging for cotton fibers and common contaminants will be presented.
