چکیده
|
This communication describes the mechanical properties of the single yarn polyester composite (pc) of cotton fiber with special reference to the effect of unevenness in the structure of yarn. unevenness % (u) and coefficient of variation (cv) in mass of spun yarn were measured. scanning electron microscopy was carried out to understand the effect of unevenness on physical structure of fibers in the yarn which affect not only the mechanical properties of yarn but also the composites reinforced with them. results also showed that decrease in 2.15 % of u in the yarn structure causes an increase of 25.18% in ultimate stress and 30.71% decrease in stiffness of composites.
