Significance and Use

The construction, composition, and color of textiles as evidence in crimes are useful comparison characteristics for forensic examinations. Textiles appear in a variety of weaves, knits, and nonwoven constructions; a combination of fabric types can occur in any one textile. There is a vast range of colors in which textiles are offered in the marketplace. Therefore, the construction, composition, and color of a textile can aid the Examiner in including or excluding a textile for consideration in a forensic examination.

A comprehensive forensic fabric or cordage examination should consist of a complete characterization of the construction and materials used in the composition of the item (such as sewing thread).
