JERSEY is a high-performance textile that lends itself to many creations and provides excellent protection.
It is easy to work with and can be sewn on a domestic sewing machine or by hand.

For the machine, use a jersey needle and a nylon or polyester thread.

Technical characteristics and uses:

  • Composed of an elastane core, this woven fabric is coated with silver for excellent protection efficiency
  • 80% elastane, 20% silver. Width 1,45m.
  • it lends itself easily to lining and making any garment requiring elasticity: hats, T-shirts…
  • Metallic grey color. This fabric is not dyed, its color is naturally that of the metal on the nylon core.

Very appreciated for the protection of the sleep: It is enough to place a length of fabric under the mattress and one above your comforter. More practical and much less expensive than a canopy.

With use, “metallic” traces may appear, without affecting the protective qualities.

To preserve its effectiveness, be sure to respect the maintenance conditions.

Without nano particles.

Line Description

Elastic, comfortable and efficient.


Cleaning is quick and easy:

  • By hand, without rubbing or twisting

    • Leave to soak for a few minutes so that the fabric soaks in properly
    • Use very little soap or non-aggressive laundry product (organic product type)
    • Press the garment as you do for a sponge or a woolen garment
    • NEVER RUB: in case of stain, use a soft toothbrush, a little soap (gall soap in organic stores) and rub gently
    • NEVER TWIST to wring out but squeeze gently
    • Dry flat or on a line, pinched regularly. Avoid full sun.
  • In washing machine

    • Place in a small laundry bag (as for underwears)
    • Use a non-aggressive laundry product (organic product type)
    • Maximum temperature 30°
    • Gentle spin in a full drum
    • Dry flat or on a line, pinched regularly. Avoid full sun.

5G Protection

Our shields, and therefore our protective clothing against waves, have been designed from the start for protection over a wide spectrum of frequencies, covering the frequencies that are now those of 5G.

Protect against Waves Shield

The shield used is

  • 100% silver: silver is the best performing metal in terms of wave attenuation, which is why we do not use any other metal
  • Totally coated with silver (and non-woven with a metal thread), which explains its remarkable performance
  • Biocompatible (see Glossary)
  • Certified without nanoparticles
  • Tested to military standard ASTM D4935-10 and/or IEEE-STD-299-2006

The principle of attenuation of the electromagnetic wave is the principle of reflection. Grounding is therefore uselesssince it is only used to eliminate overvoltages and losses of electrical charges as well as electrostatic discharges.

50 db attenuation

Thanks to the high percentage of silver used in its composition, the very high performance shielding of this article greatly reduces exposure:

  • high-frequency waves emitted by cordless DECT telephones, WLAN (wireless local area network) or Wifi wireless networks, mobile telephony, bluetooth, etc.
  • to the PLC of the Linky meter
  • to radiation from low frequency electric fields 50H

This shielding has an attenuation of 50 decibels; in other words, its efficiency is 99.999% against high and low frequencies, a reduction of 100,000 times the power of the wave (access to tests).
