Forensic Analysis of Textile Synthetic Fibers Using Different Spectroscopy Approach

Forensic medicine, an essential discipline in criminal investigations, meticulously examines evidence to exonerate individuals under suspicion. Fiber analysis, widely recognized within forensic science, plays a crucial role in this process. Despite its intricate nature, fiber analysis lacks the reliability of DNA analysis as a primary tool for perpetrator identification. This paper explores the practical application of fiber analysis in real-life scenarios, outlining a systematic approach. It begins with the identification of available fiber types, followed by a description of diverse identification methods and optimal timing for implementation. The report includes Microspectroscopy identification, rigorous comparison controls, and various sample analyses. While microscopic and instrumental analyses reveal the intrinsic composition of fibers, coloration scrutiny adds specificity, especially for fibers like cotton or wool. Challenges in forensic fiber analysis include minute sample sizes, a preference for non-destructive techniques, and complexities associated with modern dye formulations. Despite these challenges, forensic fiber analysis remains a valuable component in criminal investigations, contributing to the comprehensive understanding of evidence derived from crime scenes.
