HF (High frequency)
* Highly effective protection against electromagnetic radiations.
* Prophylaxis against electrical smog.
* Assistance by sensitivity and complaints.
* Pleasant awakable fabric.
* Permanent effect.
For optimal compatibility, finest copper threads are coated with silver. In order to prevent oxidation and electrical conductivity, the metal yarn is first coated with a polyester yarn and then coated a second time with a pure cotton yarn. Finally it is plied with another pure cotton yarn. It achieves a shielding attenuation max. ~45 dB (>99,99 %). The tight fabric is very hard-wearing.
Pollutant-examined after ÖKO Tex standard 100.

Width: 150 cm / sold by metre or in entire rolls
Composition: 97% cotton, 3% metal (silver coated yarn of finest copper)
Colors: light blue
Colour-fast and washable

Professor Dipl. Ing. Pauli of the university of the German Federal Armed Forces
in Munich, tested the screen absorption in relation to electromagnetic waves.
The fabric can be washed at 30° C on a delicate program without spinning. No tumble-dryer. Too high mechanical stress could lead to thread breakage. With the recommended treatment there is no reduction of screening even after 30 washing cycles.
