*Note: To purchase a custom length of fabric, place an order for multiple quantities of the 1ft option. The amount ordered will be cut as a single piece unless specified otherwise.
SILVER-TWIN is a compact cotton/silver fabric for the protection against high-frequency (HF) radiation. Typical application as curtain, to sew clothes, handy bags, etc..
Special feature: The frontside is made of white cotton, while the backside is densely woven with a silver thread. Despite the extremely high attenuation due to the dark silver threads on the backside, this fabric has a light gray frontside!
- Maximum high screening attenuation, even at very high frequencies!
- Excellent cost/performance ratio
- Contactable (groundable) to shield LF electric fields
- Textile characteristics: Washable, easy to iron and process
- Quality grade: Very high
Order quantity: This product is cut off according to your specifications, a return or revocation are not possible.
Screening attenuation: All stated attenuation values apply at 1 Ghz. Measurement to ASTM D4935-10 or IEEE Std 299-2006 or IEEEE Std 1128-1998 or ASTM A698/A698M-07. You find the test report above under "Report screening attenuation".
Grounding: Electrically conductive. Can be contacted and grounded to shield electric fields (LF). We recommend a plug GP or GD, with a plate GM or GS, plus a cable GC.
Fabric care: Washing at gentle cycle 30°C | Ironing without steam at degree 1 | No drying in tumble dryers | No bleaching | No chemical dry-cleaning | For allergy sufferers: Every new fabric smells, wash before its first usage!
Silver products: 1) Silver fabrics get stainings over time and often have them right from the start! If you don’t want to accept stainings or discoloration, please choose fabrics from Swiss-Shield®., 2) Silver fabrics have a limited durability, which depends on the frequency of movement., 3) Our silver fabrics don’t contain nano-silver, but a thick pure metallic silver layer.
Fabric quality: We only sell top quality fabrics! However, due to the high production costs and in favor of a reasonable retail price, tiny defects (e.g. a flaw in weaving) are no reason for complaint. We appreciate your understanding.
