Standard Guide for Forensic Examination of Fibers

Importancia y uso:

5.1 Fibers are frequently encountered in casework, whether it be through the evidentiary item itself (for example, clothing, rope), or through the processing and collection of fibers from evidentiary items. Fibers can be exchanged between individuals, between individuals and objects, and between objects.

5.2 Fibers are subjected to a variety of manufacturing processes in order to produce textile materials for application in a wide range of industries (for example, automotive, clothing, home furnishing). Factors such as end use, current trends, and availability influence the type, color, and frequency of fibers incorporated into textiles.

5.3 Fibers exhibit a wide range of physical characteristics, including color, optical properties, spectral properties, and chemical compositions due to the manufacturing process, end use, and exposure to post-manufacturing changes (for example, exposure to various environmental conditions, chemicals, etc.). These characteristics and properties are observed, analyzed, and compared during a fiber examination.
