The Identification of Acrylic Fibers by Polymer Composition as Determined by Infared Spectroscopy and Physical Characteristics
Acrylic fibers are now regularly encountered in the investigation of crime mainly due to their widespread use in the manufacture of outer clothing and carpets. Although acrylic fibers are easily recognized as a group, making a specific identification is particularly difficult. The sample available for identification and comparison in forensic science laboratories may be restricted to a few single fibers, a condition which imposes severe limitations on the value of existing identification schemes for acrylic fibers.
