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 103 to 105 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.
