Shielding Textiles as Everyday Clothing: Design, Fit and Trade-offs

Conductive textiles are not new. They have been used for decades in EMC test facilities, in industrial enclosures, in military and aerospace applications, and in electrostatic-discharge control for electronics manufacturing. What is relatively new is the attempt to make them work as ordinary clothing.

That turns out to be a genuine engineering problem, and it is worth understanding before you buy.

The core trade-off

The properties that make a textile shield well — high conductive fibre content, dense weave, continuous conductive surface — are broadly the opposite of the properties that make it comfortable: light, breathable, soft, drapeable, and tolerant of laundering.

Every shielding garment sits somewhere on that trade-off. A dense industrial shielding cloth performs better and is unpleasant to wear. A soft, breathable blend is comfortable and attenuates less. Anyone claiming to have eliminated the trade-off entirely is describing marketing, not textiles.

What a good manufacturer does is choose a sensible point on that curve for the garment's purpose, and tell you where it landed.

Why fit affects performance

This is the part that is least intuitive. A garment is not a sealed enclosure, and its attenuation in real use depends heavily on how it sits.

• Coverage. Shielding fabric affects the area it covers and nothing else.
• Gaps. Openings at the neck, cuffs, hem and front closure pass signal. A fastened jacket performs differently from an open one.
• Contact and drape. Fabric held away from the body behaves differently from fabric against it, particularly at higher frequencies.

This is why we publish fabric-level test data and then tell you plainly that a finished garment does not perform as the flat fabric does. Both facts are true and you need both.

Durability is the real quality signal

Conductive coatings degrade with wear and washing. The meaningful question about a shielding garment is not how it measures new, but how it measures after a year.

That comes down to construction: whether the conductive fibre is woven throughout or applied as a surface coating, the density of the conductive content, the quality of the stitching at stress points, and whether the garment was designed to be laundered gently.

It is also why our care instructions are specific rather than generic. Cold water, neutral detergent, no bleach, no fabric softener, no chlorine, air dry, no iron — each of those protects the conductive layer.

Where the range sits

Our Body Guards range covers tees, wraps, briefs, headwear and outerwear, built from conductive silver-fibre textiles and cut to be worn normally rather than to maximise a laboratory number. Test documentation is available for any of them on request.

If what you actually want is full isolation of a device rather than area coverage on a body, a sealed Stuff Guard is the right product and a garment is not.

We make no health claims for our products. What we sell is measurable shielding performance and the documentation to prove it.
