Contains reference spectra of commercially available synthetic fibers measured by FTIR/Microscope. The spectra were measured on 440 fiber and yarn samples, and multiple spectra are provided for two or more components in a yarn. The database includes chemical classification, trade name and manufacturer identification. The spectra were measured on the Reference Collection of Synthetic Fibers assembled by Collaborative Testing Services Inc., Herndon, Virginia, U.S.A. The spectra were measured by Dr. Eileen J. Carnahan, Micro-Scan Services Inc., Schenectady, New York, U.S.A. All databases undergo the Sadtler Data Review Protocol to provide you with the highest standard available in spectral data today. These rigorous qualifying procedures start at data acquisition and continue throughout the database development process.1.) Purity checked by another spectral technique. 2.) Chemical and physical properties listed. 3.) Chemical composition defined. 4.) Chemical structure included. 5.) Sampling technique listed. 6.) Databases created specifically for searching. 450 Spectra; Sadtler Product Code: 4364
