Yarn Strength
- Jan 06, 2018 -

Yarn strength is an indicator of yarns' tension. There is absolute strength and relative strength. The absolute strength is breaking strength; it refers to the force the yarn can bear from stretching to break. It has the single yarn strength, plied yarn strength and skein strength; this can be Newton, Diane, Chris, kg force or pounds force.

Relative strength is: (1) breaking strength, the external force on the unit area of yarn when tensile yarn is broken; (2) specific strength, when tensile yarns are broken, the external force that a unit of fineness can bear; (3) breaking length, the length of the yarn when the yarn weight equals its breaking strength. (4) quality index, an indicator of the relative strength of the yarn.

Yarn strength is one of the most important routine inspection items in textile production.
