  • the only shielding material world-wide which incorporates high textile properties
  • effectively protecting from electrical fields and electromagnetic interference (electro smog) 
  • woven with yarns that contain a very thin silver coated metallic yarn in the core
  • available in cotton or polyester
  • very fine, translucent, washable, soft and decorative (dyeable and printable)
  • easily processable for the most diverse applications

Swiss Shield offers optimal protection everywhere where humans, data or equipment should be protected against electrical fields and electromagnetic rays.

Swiss Shield conductive spun yarns for EMI protection


Swiss Shield yarns are available in a wide count range, from very fine to extremely coarse.

Different base materials, such as polyester, polyamide or aramids, can serve whereas customer can choose the conductive element between metals like gold, silver, copper or any other electrically conductive type. Furthermore, an insulating surface can be optionally chosen aswell.


Swiss Shield yarns form the base for the production of Swiss Shield textiles with specifically variable characteristics.

Swiss Shield textiles are available in grammages of between 40 gr/m2 to 250 gr/m2 and provide shielding from a few dB to over 80 dB. Swiss Shield textiles are as simple to process as normal fabrics.
