THE ELECTRICAL AND PHYSICAL EFFECTS OF YARNS CONTAINING METAL WIRE ON KNITTED FABRIC

Abstract

The textile industry is developed with the proliferation of technological developments and the functionalization of products about conductive textile structures day by day. Many applications could be seen including metal yarns and knitted or woven fabrics containing metal wire. This paper reported analyze that fabrication method, physical, electrical and electromagnetic shielding (EMSE) properties for knitted fabrics with single and double folded yarn, which has stainless steel wire. Polyester /Stainless steel wire (80/20) yarns were used in single (Nm 50/1) and double (Nm 50/2) folded structure. These yarns were produced as single jersey knitted fabric in sock machine. The fabric structures were formed by using conductive yarns containing metal wires as upper yarn, 70/20 denier lycra white yarn as lower yarn. The physical properties including tensile, twist, and evenness of metal yarns were analyzed. The properties such as pilling, abrasion, conductivity, EMSE of single jersey knitted fabrics were measured. Knitted fabric with double folded yarns was better pilling, abrasion, EMSE, surface, and volume resistivity values compared to fabric containing single folded yarns. The density of metal yarn in knitted fabrics was directly effective on the pilling, abrasion, conductivity and EMSE results. Knitted fabric with double folded yarns was appropriate to structure for using in EMSE applications and electronic textiles.
