Fiber forensics definition A fiber is the smallest unit of a textile material that has a length many times greater than its diameter. Fibres are probably the most abundant form of trace material. Identifying rare or unusual fibers at a crime scene has increased in significance, as it may place a suspect at the scene of the crime. The processing of fibre evidence in the forensic science laboratory can be divided into recovery, identification, comparison and evaluation. The latter examination consists of determining whether the questioned fiber has the same chemical, microscopic and optical properties as a known sample. Find out how NCFS conducts research and develops methods for fiber analysis and identification. They can be used to provide evidence in a wide variety of criminal cases. Forensic fiber tests are used to identify the type of fiber and to distinguish between natural and synthetic fibers. Fibers can occur naturally as plant and animal fibers, but they Fibers are one of the several pieces of forensic evidence known as trace evidence. They also help in determining the chemical composition of fibers and identifying any dyes or treatments that have been applied to the fibers[4].

The most common sources of transferred fibers are clothing, drapes, rugs, furniture, and blankets. Forensic fiber examination includes both physical match of fabric or cordage based on damaged or cut edges and individual fiber comparisons. Fibers are gathered from a crime scene using tweezers, tape, or a vacuum. Learn about forensic fiber examination, which involves comparing fibers based on their physical, chemical and optical properties. Fiber Evidence.
