BLACK-JERSEY fabric EMF shielding is a compact cotton fabric with high silver content for HF+LF shielding. Typical application to sew articles of clothingDue to the jersey-typical elasticity perfect for close-fitting laundry. Actually, our best and most stable apparel fabric.

  • Very high screening attenuation for a fabric with such a high cotton content.
  • Textile characteristics: Easy to sew, wash and iron.
  • Quality grade: Very high

Silver products

  • Silver fabrics have a limited durability, depending on the frequency of movement.
  • Our silver fabrics do not contain any nano silver, but a thick metallic silver coating.

Attenuation | Grounding

  • This product shields high frequency electromagnetic fields (HF). The indicated dB-values apply to 1 GHz, view chart for other frequencies. Laboratory report ranging from 40/600 MHz to 40 GHz according to standards ASTM D4935-10 or IEEE Std 299-2006, view report above.
  • This product without an electrically conductive surface does not shield low-frequency alternating electric fields (LF).

Additional Information

Shielding attenuation HF

This product shields high frequency electromagnetic fields (HF). Unless otherwise stated, the indicated dB-values apply to 1 GHz. Measurement from 600 MHz to 40 GHz according to standards ASTM D4935-10 or IEEE Std 299-2006.

Laboratory & expert report of shielding attenuation up to 40 GHz

We have already invested in our own professional EMV laboratory years ago. We not only use it to create our laboratory screening reports but also to check each batch daily. Additionally, we have all our products checked by an independent, well-respected expert. Double checked for twice the safety. Please find the reports above in Data Sheets.
