WebFilament yarns are sometimes twisted to a fairly high level to break up the luster of the yarn or to impart some other attribute to the yarn for effect purposes. However, high twist levels reduce the tenacity of the yarn and make the yarn leaner (i.e. have a smaller diameter). Another use of twist in filament yarns is to create texture. Tenacity is the customary measure of strength of a fiber or yarn. It is usually defined as the ultimate (breaking) force of the fiber (in gram-force units) divided by the denier. Because denier is a measure of the linear density, the tenacity works out to be not a measure of force per unit area, but rather a quasi-dimensionless measure analogous to specific strength. A tenacity of corresponds to: Mostly Tenacity expressed in report as cN/tex.

WebJun 10, 2014 · The super high tenacity fibres are used essentially for spinning 100% polyester sewing threads and other industrial yarns. The higher tenacities are obtained by using higher draw ratios and higher annealer temperatures upto 225 to 230 degree C and a slight additional pull of 2% or so at the last zone in annealing.
