How to Choose Conductive Yarn for EMF & EMI Shielding
How to Choose Conductive Yarn for EMF & EMI Shielding Choosing the right conductive yarn for EMF and EMI shielding is rarely a straightforward decision. The market is crowded with silver-coated nylons, stainless steel blends, copper-nickel hybrids, and pure metal fibers — each with different conductivity, durability, and cost profiles. Pick wrong, and your fabric may fail shielding tests, irritate skin, or corrode after a few wash cycles. This guide breaks down the selection process into practical steps, covering fiber type, conductivity targets, textile compatibility, and certification requirements. It's written for product developers, procurement managers, and textile engineers who need a defensible, data-backed choice rather than a vendor's sales pitch. Key Takeaways Match fiber type to application: stainless steel for durability, silver for high conductivity, copper-nickel for cost balance. Specify shielding effectiveness in decibels (dB) — 30 dB blocks 99.9% of r...
