Abstract
In this investigation the complex copper core spun yarn (Cotton Sheath and Polyester Sheath) of 179, 118, 98, and 84 tex count of copper core yarns were produced by Dref friction spinning machines and the count of 74 and 59 tex of copper core yarns (cotton sheath and polyester sheath) were produced by ring spinning machines with core attachments device for electromagnetic shielding yarn production purpose. The article reports the effects of the process variables on tensile properties of the copper core yarn as well as individual core and sheath components. Various parameters such as Spinning drum speed, the sliver material, core materials, and count of the yarn were changed to investigate how various parameters affects the tenacity of the complex copper core spun yarn.
