Manufacturing Technique and Physical Property of Metal Wires/ PP Nonwoven Selvedges Complex Ply Yarns and Knitted Fabrics

Abstract:

In this study, nonwoven selvedges served as core yarn which was wrapped with stainless steel wires. Core yarn was added with functional materials such as stainless steel wires or copper wires or both. Functional polypropylene nonwoven selvedges (PNS) complex ply yarns were made using a rotor twister machine. The wrapped density of stainless steel wires was changed as 0.5, 1.5, 2.5, 3.5 and 4.5 turns/cm and the speed of rotor twister was set at 8000 rpm. Shown in the mechanical property test of complex ply yarn, when speed of rotor twister was at 8000 rpm; wrapped density was 2.5 turns/ cm; and functional materials were copper wires and stainless steel wires, complex ply yarns made of polypropylene nonwoven selvedges (PNS) had the maximum breaking force as 47.76N and maximum breaking elongation as 47.93%.
