Breaking tenacity

Breaking tenacity is a term used to describe the tensile stress at rupture of a fibre, yarn, cord, or filament, expressed as the following: Newton per Denier or Tex measured in gram or force. The breaking tenacity is calculated from the breaking load and linear density of the unstrained sample or achieved directly from tensile testing machines, which can be suitably adjusted to indicate tenacity instead of breaking load for samples of known linear density. Breaking tenacity expressed in gram or force per Tex or Denier is numerically equal to breaking length expressed in kilometres.
