Why bamboo viscose is not antibacterial

Short answer: The fibre does not kill bacteria. It moves the moisture away from the skin, and drier skin gives the bacteria less to live on. That is an indirect effect.

The difference matters

An antibacterial treatment kills bacteria. Moisture transport removes what they live on. The result resembles each other, but the mechanism is different. See facts about bamboo.

That is why the effect can disappear

If the fabric saturates with moisture, or fabric softener lays a film on it, the effect stops. An antibacterial treatment would not do that. See washing and care.

What it means in practice

In socks and underwear the difference is clearly felt, because it involves moderate moisture over a long time. See bamboo underwear for men.

With heavy sweating

With very heavy sweating the fibre saturates, and the advantage disappears. Then you have to change. See bamboo underwear for women.

Be careful with claims

Claims about antibacterial properties in textiles are regulated. We stick to what can be explained. See advantages of bamboo viscose.

Frequently asked questions

Is bamboo viscose antibacterial?

No. It moves moisture away from the skin, and dry skin gives bacteria less to live on.

Why do bamboo socks smell less then?

Because the foot is kept drier, not because bacteria are killed.

Can the effect disappear?

Yes. On saturation, or if fabric softener lays a film on the fibres.
