Fiber identification is an important first step when developing the base for your textile product. Various laboratory methods are available to identify the structural, physical and chemical properties of a fiber, including microscopic, burn and solubility tests. Establishing the identity of the fiber helps the manufacturer to first understand whether or not it is suitable for its intended end use and, if so, what is the best way to take care of the fabric made with these fibers.

Tensile testing of yarns is used to determine the breaking force, elongation, and toughness properties of the yarn. Breaking tenacity, a ratio of the breaking force to yarn linear density is also a common property for evaluating the strength of a yarn material and for comparison and validation purposes. Tensile testing of yarn to determine properties such as breaking strength and elongation includes the use of a tensile testing machine and unique grips to hold the yarn.
