Process of complex core spun yarn containing a metal wire

Nearly all electrostatic dissipating yarns or fabrics are fabricated from a man-made carbon conducting core surrounded by a sheath of polyester or nylon, electroplated staple fiber, fabric or stainless steel staple fiber. Few electrostatic dissipating materials are spun from continuous, well conducting metal wires. This work uses metal wire as the core and fabricates the yarn using a ring-spinning machine. The copper and stainless steel wires were employed as core materials, and rayon and T/R (polyester/rayon) roving were used as cover materials. During the spinning process, the metal wire was fed from the front rollers and underwent drafted roving to spin yarn with a complex core. The guide device was designed and installed on the roller-weighting arm to increase the stability of spinning of the metal wire. Various parameters such as the core materials, the roving materials, the twist level and the count of the spun yam were changed to investigate how various parameters affect the tenacity and hairiness of the complex core spun yarn.
