Electrosmog shielding fabric sold by the metre for custom textile products
Electromagnetic shielding fabric is a textile containing conductive fibres that can be used to attenuate high-frequency electromagnetic fields. Fabric sold by the metre allows you to determine the required length and create a textile product suited to the intended application.
The documented widths of the fabrics in this category generally range from 150 to 300 cm. Wider versions can reduce the number of seams required for curtains and canopies, while narrower, elastic or denser materials can be used for garments and smaller sewing projects.
What can electromagnetic shielding fabric be used for?
Electrosmog shielding fabric for curtains, canopies and screens
Transparent or semi-transparent fabrics can be used to make curtains, net curtains and canopies. These materials create textile shielding while allowing part of the light to pass through. White and off-white versions can also be used in bright living areas and bedrooms.
Denser, less transparent fabrics can be used for screens, shielding covers, smaller storage covers and other textile surfaces. Some versions are also suitable for clothing, but the appropriate elasticity, texture and material composition must be selected for this purpose.
Transparent shielding curtain fabric for windows and canopies
Which electrosmog shielding textile allows light to pass through?
Transparent polyester voile and Trevira-based fabrics can be used for curtains and canopies. The documented versions are available in widths of 250 or 300 cm and provide shielding attenuation between 23 and 38 dB. These textiles are white and have a crease-resistant construction.
Semi-transparent cotton and viscose fabrics provide a denser surface. The documented 250 cm wide versions include materials with shielding attenuation of 38 and 42 dB. These off-white fabrics can also be used for curtains and canopies.
What are the differences between cotton, polyester and viscose fabrics?
Cotton, polyester and viscose electromagnetic shielding fabric
The polyester-based materials include wide, transparent and crease-resistant curtain fabrics. Cotton-containing versions are available in semi-transparent or opaque constructions, and several types provide a pleasant textile surface for curtains or garments.
Viscose-based semi-transparent fabrics are available in an off-white colour. One documented version may only be dry-cleaned. The cleaning method should therefore be considered together with the appearance and shielding value.
Opaque conductive textile for garments and smaller shielding products
When should an elastic electrosmog shielding fabric be selected?
Elastic cotton jersey is intended for garments. The documented version contains 83 percent cotton, is 150 cm wide and provides 40 dB shielding attenuation. Its elastic structure can be used for sewing projects where the finished textile must follow body movement.
A fully silver-plated elastic spandex fabric is also intended for garments. It is 160 cm wide and provides 51 dB shielding attenuation. Its silver-coloured surface and elastic construction differ from the appearance and texture of cotton jersey.
How should shielding attenuation be interpreted?
Shielding attenuation of shielding curtain fabrics
Shielding attenuation is a value expressed in dB that indicates the measured performance of the fabric against electromagnetic waves. A higher dB value represents greater documented attenuation. The value always applies to the specific material and the relevant measuring conditions.
- Transparent fabrics include documented versions with 23, 38 and 47 dB attenuation.
- Semi-transparent cotton and viscose materials include versions with 38 and 42 dB attenuation.
- Elastic garment fabrics may have documented values of 28, 40 or 51 dB.
- Opaque cotton and stainless-steel-containing fabrics include versions with 42 dB attenuation.
The dB value must be considered together with the intended use. A wide transparent curtain fabric and an elastic garment textile are designed for different applications and cannot be compared solely by their shielding value.
Selecting fabric by light transmission, colour and texture
Which shielding fabric suits the room?
In bright rooms, transparent white voile or Trevira fabric can be used where light transmission is important. Off-white, semi-transparent cotton and viscose materials provide a denser appearance, while grey, beige or silver fabrics create a more pronounced textile surface.
The texture of cotton-containing materials differs from polyester voile, viscose and fabrics containing stainless steel fibres. For garments, elasticity and the side that touches the skin are particularly important. For curtains, light transmission, drape and dimensions may be the main selection criteria.
Which widths are available for electrosmog textile shielding?
Electromagnetic shielding fabric from 150 to 300 cm wide
The documented fabric widths are 150, 160, 200, 245, 250 or 300 cm. The ordering unit is one linear metre, so each ordered unit consists of a one-metre-long piece in the full nominal width of the selected fabric.
When calculating the required quantity, the surface dimensions, hems, folds and seam allowances must also be considered. For curtains or canopies, the finished textile dimensions may differ from the simple width of the area to be covered.
Washing and cleaning shielding fabrics
How can conductive textiles be cleaned?
Cleaning requirements vary by fabric. Some cotton and stainless-steel-containing materials can be washed at up to 60 degrees Celsius, while certain viscose fabrics may only be dry-cleaned. The cleaning instructions of the selected fabric should therefore be checked before purchase.
Textiles containing silver or steel fibres may have specific care requirements. Unsuitable detergents, chemicals or cleaning methods may affect the material surface, so the finished product must always be cared for according to the instructions for the selected fabric.
When is a groundable shielding fabric required?
Selecting a groundable electrosmog shielding fabric
The fabric range includes both groundable and non-groundable versions. Grounding capability does not automatically follow from the fact that a fabric is conductive or contains metallic fibres. Only textiles specifically identified as groundable may be treated as such.
A grounding accessory specified for the selected textile is required to connect a groundable fabric. The electrical connection and commissioning must be carried out by a qualified electrician.
Making a shielding canopy, curtain or garment from fabric sold by the metre
Which electrosmog shielding fabric is suitable for which application?
- Transparent voile or Trevira fabric can be selected for curtains and canopies.
- Semi-transparent cotton or viscose can be used for denser curtains.
- Elastic cotton jersey and spandex fabric can be used for garments.
- Opaque cotton and stainless-steel-containing textiles can be used for curtains, garments or smaller covers.
- Groundable fabric requires the specified connector and grounding system.
The processing method must be planned according to the fabric's elasticity, transparency and material composition. The appropriate sewing technique and edge finish may vary by product.
What should be considered before ordering and processing fabric sold by the metre?
Ordering criteria for electrosmog textile shielding
Before ordering, determine the purpose, size and required light transmission of the finished textile product. Check the fabric width, shielding attenuation, colour, material composition, elasticity, cleaning requirements and grounding capability.
We recommend calculating the required quantity together with seam allowances, hems and any folds. This allows the cut fabric dimensions to match the planned curtain, canopy, garment or other textile product.
Frequently asked questions about electrosmog shielding fabrics
