Strain characteristics of cotton yarns depending on the strain rate and methods of their manufacture

One of the main reasons for nonlinearity tension diagrams cotton yarns is variability their moduli elasticity and plasticity under strain. The changes in strain obtained from tensile confirm this. curve has ten parameters, values which depend on method yarn manufacture rate. Based results processing yarn, by carded combed systems ring rotor spinning (CD-carded ring-spun, OE-carded rotor-spun, CM-combed ring-spun), at rates 0,0033 s-1 to 0,033 s-1, these parameters were determined analyzed. Their quantitative qualitative dependence rate are shown.
