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).
1.1 The intent of this guide is to assist individuals and laboratories conducting examinations of fabrics and cordage. It is not designed as a detailed methods description or protocol for the analysis and comparison of fabric and cordage evidence, but as a guide to an acceptable procedure to strengthen the usefulness of the analytical method.
1.2 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.
