Shielding fabric Köper

Shielding fabric for bedding and clothing, OEKO-TEX Standard 100.

Finest copper threads are coated with silver for optimal compatibility. To exclude electrical conductivity and prevent oxidation, the metal thread is covered with polyester. Now the whole is covered with cotton and the resulting yarn is twisted with a second, pure cotton yarn.
The shielding effect of the ultra-fine metal mesh in the fabric prevents electromagnetic radiation from penetrating.

The extra dense fabric is very durable.
