Structure of Spun Yarn and Its Mechanical Non-linear Property in Initial Tensile Deformation

Static Failure Mechanism of Staple Yarns: A Critical Review

“…They explained that the cotton fibers fail first because of its low strain to break. The studies on blended twisted yarn by Machida [29], Monego et al [30] and staple yarns at small extensions by Carnaby et al [31] and Narota et al [32] explained that the stressstrain curves of ring spun yarns can be divided in to at least three regimes: an initial non linear regime, and a secondary linear regime and a third low average tangential modulus regime with load undulation. The initial two zones reflect the cooperative contribution of the cotton and polyester fiber stress-strain behavior; the third regime reflects the stress-strain behavior of the polyester fiber accompanied by multiple breakages of cotton fibers.…”
