A new rotor-wrapping-twister is used to produce new yarns comprising stainless steel filaments, polypropylene nonwoven tapes, and reinforcing filaments. Rapier looms are used to weave commingled fabrics from these yams. The electrical properties of thermo plastic commingled laminates are investigated for the commingled fabrics and for lami nates heated at 170°C for 60, 90, 120, and 150 seconds. In this study, 3.65-4.89 wt % stainless steel filaments are used to determine the conductivity of the thermoplastic commingled laminates. The surface resistivity of these laminates is in the range of 10 3 to 10 5 ohms/square. The shielding effectiveness is in the range of 30 to 60 dB. The electromagnetic shielding effectiveness of these laminates is sufficient to enable them to be used as electromagnetic shielding materials.
