fiber analysis
Thread evidence testing
Fiber analysis is the forensic examination of textile fibers to identify their origin, composition, and characteristics.
Crime labs compare fibers found at scenes—on clothing, carpets, or vehicles—to determine whether they match known sources: Fiber analysis linked the suspect's sweater to threads found on the victim.
The technique can identify fiber type, dye composition, and manufacturing characteristics.
