Static electricity in clothes in winter

Short answer: Static electricity builds up when the air is dry and two materials rub against each other. Natural fibres such as bamboo viscose take up moisture and therefore become static less often than synthetics.

Why it happens in winter

Indoor air is dry when the heating is on. Dry fabric cannot lead the charge away, so it builds up instead.

Synthetics are worst

Polyester and nylon take up almost no moisture and therefore become the most static. Bamboo viscose takes up moisture from the air.

The layer closest to the skin

If the innermost layer is natural, less happens. See bamboo vest for women.

The slip

A smooth slip between dress and tights stops most of the clinging. See bamboo slip.

Moisture in the room

Slightly higher indoor humidity reduces the problem noticeably. The drying rack with wet laundry actually helps.

Not fabric softener

Fabric softener is marketed against static, but it lays a film that reduces moisture transport. See antistatic clothes.

General washing

The rest of the rules are in the washing guide.

Bedding and nightwear

Static is also felt in bed, where a synthetic sheet can give sparks in winter. Bedding in natural fibres takes up moisture and does not. See bamboo bedding.

Tights

Tights in synthetic material are the most common reason a dress clings. See bamboo tights for women.

Frequently asked questions

Why does the dress cling in winter?

Because the air is dry and tights in synthetic material become static.

Does fabric softener help?

It dampens it, but lays a film and reduces the moisture transport of the fabric.

What is the easiest solution?

A smooth layer in between, for example a slip.
