Bamboo viscose versus microfibre
Short answer: Microfibre is extremely thin synthetic fibre that dries quickly. Bamboo viscose feels softer against the skin and sheds no plastic in the wash.
What microfibre is
Microfibre is polyester or polyamide spun into very fine threads. The large surface area makes the fabric efficient at moving water, which is why it is used for cleaning cloths and sportswear.
In clothing next to the skin
Microfibre can feel soft but does not let air through in the same way. Many people find it clammy after an hour. Bamboo viscose takes moisture into the fibre and feels drier. See bamboo underwear for women.
Odour
Microfibre holds skin oils and starts to smell quickly. That is why sportswear in microfibre often has to be washed after every use. See bamboo t-shirts for women.
Microplastic
Microfibre sheds plastic fibres in every wash. Bamboo viscose is cellulose and sheds no plastic. See bamboo clothing for women.
Frequently asked questions
Is microfibre better for towels
For travel towels yes, because they dry fast and pack small. At home bamboo is softer.
Why is microfibre used in sportswear
Because it dries quickly and weighs little. The drawbacks are odour and clamminess.
Can microplastic from the wash be reduced
A laundry bag that catches fibres helps, and fewer washes at lower temperature also makes a difference.
