Any text on fiber examination starts with fibers, the basic units of a textile, and works its way up to fabrics and garments. macroscopically, hairs have a root, shaft, and tip. microscopically, the three main structures are the cuticle, the cortex, and the medulla. The present study entitled "characterization of natural and synthetic fibers for forensic purposes" was carried out at the department of forensic science, sam higginbottom university of agriculture technology & sciences, prayagraj. Fibers and hairs are abundant and easily transferred trace evidence that can link individuals or items to a crime scene or contact with a victim. textiles represent a major source of fibers and are either of natural origin or manmade synthetics. This document is an outline of fiber analysis methods intended for use by forensic fiber examiners. the particular methods employed by each examiner, laboratory, or both will depend upon sample size, sample suitability, laboratory equipment, and examiner training.
