T-shirts and static electricity

Short answer: Static builds up in dry air when two materials rub against each other. Natural fibres such as bamboo viscose absorb moisture and carry the charge away better than synthetic fabrics, so they cling less.

Dry air is the precondition

In winter the indoor air is dry, because cold outside air is warmed up and loses its moisture. Then the charge stays in the fabric instead of disappearing. When the air is humid, it fades on its own. This applies to every fabric, including the styles in women's bestsellers, but some materials are more prone than others.

Friction creates the charge

The charge forms when two materials rub against each other, such as a T-shirt against a jacket or hair against a jumper. The more different the materials are, the more charge builds up. That is why a synthetic outer layer over a T-shirt often causes more static than two layers of similar fabric. Swap one layer and feel the difference.

Moisture in the fibre helps

Bamboo viscose absorbs a fair amount of moisture from the air, and that makes the fabric less static than polyester. The moisture in the fibre carries the charge away before it builds. That is why a bamboo viscose T-shirt clings less often, even on dry winter days. See the qualities in Copenhagen Bamboo bestsellers.

Avoid the tumble dryer

Tumble drying makes the fabric completely dry and charged, because the clothes rub together in warm, dry air. When you take them out, they stick together and crackle. Air drying solves it for most people and is gentler on the fibres. Dry clothes indoors in winter to add moisture to the air. This goes for every women's bamboo sweatshirt too.

Fabric softener is a trade off

Fabric softener reduces static because it leaves a thin coating on the fibres. But the coating also makes the fabric worse at absorbing and moving moisture, which is exactly what makes bamboo viscose pleasant. Many also find the fabric becomes less soft over time. So try air drying and more humid air first.

Humidity at home

A bowl of water on the radiator, laundry drying indoors or a humidifier can raise the humidity in a room. That reduces static in clothes, rugs and hair. Air the room briefly and fully rather than leaving a window ajar all day. That way the room keeps its warmth and the air does not get needlessly dry.

Put the layers together

Static is often about the whole outfit, not just the T-shirt. If you wear a synthetic fleece or a polyester jacket on top, it can create charge whatever you have underneath. Choose layers of similar material, or an outer layer in natural fibres. Then the materials rub less against each other, and your clothes cling less.

A quick fix for everyday

If the T-shirt clings, dampen your hands slightly and smooth them down over the fabric. That carries the charge away at once. You can also touch something metal, such as a water pipe, before taking off a jumper, so you discharge first. These are small tricks, but they help on the driest winter days.

Frequently asked questions

Does fabric softener help against static

Yes, but it coats the fibres and makes the fabric worse at moving moisture. Try air drying and slightly more humid air first.

Why do clothes cling in winter

Dry indoor air and a synthetic layer somewhere in the outfit. Swap that layer for something in natural fibres and notice the difference over a few days.

Can static be removed quickly

Dampen your hands slightly and smooth them over the fabric. That carries the charge away at once, and the T-shirt hangs neatly again.
