Forensic Examination of Fibres

Book excerpt: In order for forensic fibre examiners to fully utilize fibre and textile evidence during their analysis, they require not only specialised forensic knowledge but also in-depth knowledge of fibres, yarns and fabrics themselves. Production, both the chemical and physical structure, and the properties of these materials is required in order to determine the value of fibre evidence. This includes knowing production figures, fashion changes, sudden arrivals of new materials, dye variability, and numerous other factors that may have a bearing on the information obtained. Fully updated with the latest advances, Forensic Examination of Fibres, Third Edition continues in the tradition of the First (1992) and Second Editions (1999) as the premier text on the subject of forensic fibre analysis. The international team of contributing authors detail the recovery of the evidence—through the different stages of laboratory examination—to the evaluation of the meaning of findings. The coverage has been considerably expanded, and all material, has been revised and wholly updated. Topics covered include examining damaged textiles, infrared microspectroscopy and thin layer chomatography, and colour analyses. This edition also highlights the critical role of quality assurance in ensuring the reliability of the technical observations and results, and, in doing so, looks at the implications of supervisory managers and labs in the accurate and responsible analysis of such evidence. Features include: Outlining evidentiary process from collecting and preserving the evidence at the crime scene through the laboratory analysis of fibres Detailing the latest developments and emerging technologies including Kevlar and other such advances in fibre technology Coverage of a broad array of fibres both, natural (cellulose, protein, and mineral) and man-made fibres including synthetic, inorganic and regenerated Forensic Examination of Fibres, Third Edition is a much-needed update to the classic book, serving as an indispensable reference to crime scene technicians, laboratory forensic scientists and microscopists, students in police, forensic, and justice science programs.
