Unit 2: CSI Unit Training Materials: Fiber Evidence

These flashcards cover key concepts related to fiber evidence in CSI unit training, including definitions of fiber types and characteristics.

Fiber

The smallest unit of a textile material that has a length many times greater than its diameter.

Natural Fibers

Fibers derived from plants and animals, such as cotton and wool.

Synthetic Fibers

Man-made fibers created using polymers made from petroleum products.

Cross Transfer

The phenomenon where fibers are transferred between a suspect's clothing and a victim's clothing, indicating possible physical contact.

Characteristics of Fiber Evidence

Includes type, length, shape of the fiber, spinning method, fabric construction, and dye composition.

Cotton

The most commonly used plant fiber in textile materials.

Wool

The most common animal fiber used in textile materials, primarily sourced from sheep.

Polymer

A substance composed of large molecules formed by joining together smaller units, used to create synthetic fibers.
