Antibacterial Bamboo – What Does the Research Say?

Short answer: Raw bamboo contains substances that inhibit bacteria, but some of that effect is lost when bamboo is chemically turned into bamboo viscose. On the other hand, bamboo viscose moves moisture extremely well, and dry fabric gives bacteria poor conditions. That is why many people find that bamboo clothing smells less than cotton and polyester, even though it is not a disinfecting material.

What does antibacterial bamboo actually mean?

The bamboo plant survives in nature without pesticides, and part of the credit goes to a substance called bamboo kun, which inhibits bacterial growth. That is the property people usually point to when bamboo clothing is called antibacterial. But your clothes are made from bamboo viscose, where the plant has been dissolved and spun into new fibres, and here the picture is more nuanced.

What does the research say about bamboo viscose?

The studies point in different directions. Some find a small bacteria-inhibiting effect in bamboo viscose, others almost none. The honest answer is that the difference in practice comes from moisture handling: bamboo viscose carries sweat away from the skin, and bacteria do not thrive in dry fabric. You can read more about the mechanism in our post on bamboo and temperature regulation and about the difference between the fibre types in bamboo lyocell vs. bamboo rayon.

What does it mean for you day to day?

In practice it means less odour in socks and underwear, because sweat does not linger in the fabric. You notice it most clearly in bamboo socks for men and bamboo socks for women, and in bamboo underwear for men and bamboo underwear for women. Expect fresh clothes, not a medical product.

Frequently asked questions

Is bamboo clothing antibacterial?

Partly. Raw bamboo inhibits bacteria, but the effect is reduced in bamboo viscose. The main reason for less odour is that the fabric keeps your skin dry, so bacteria grow more slowly.

Does bamboo clothing smell less than cotton?

Yes, that is what most people experience. Bamboo viscose carries sweat away from the skin, and dry fabric means less bacterial growth and therefore less odour.

Can bamboo clothing replace good hygiene?

No. Bamboo clothing can help keep you fresh for longer, but it does not replace washing both your body and your clothes daily.
