چکیده
The effect of twi st on the performance of polyethylene naphthal ate, dimensionally stable polyester and high-tenacity polyester cord yarns has been studied. h is observed that the twi st has a very important effect on the tensile properties, creep properties and fracture mechani sm. An increase in the twi st leve l increases breaking elongation and creep rate but decreases break ing strength. Breaking mechanisms are also affected by the twist level. However, it is found that the material has the most important role on the cord performance.

متن کاملPretreatment dependence of mechanical and surface properties of cotton ring- and OE rotor-spun yarns
The variations in the mechanical and surface properties of cotton ringand OE rotor-spun yarns on exposure to different chemicals during wet processing have been studied. It is observed that the structure and yarn twist are the dominant parameters in determining the accessibility of chemicals during wet processing. The most distinct outcome of alkaline scouring of cotton yarns, in comparison to ...
