One reason for using bamboo fibre is, of course, that it’s deemed to be natural and renewable. True, in a sense, but the processing involves lots of energy and petrochemicals. Of course, improvements are possible, and it’s hard to argue against something that grows like this without fertiliser or insecticides (in my case).
I’d rather look at bamboo fibre as a competitive product. What are the undies like? They’re soft, cool in summer, warm in winter, ventilate and evaporate well, and tend not to smell. Bamboo fabric is also classed as non-allergenic, though I’d be amazed if dust mites don’t manage to live in it, here in Eastern Oz, the dust mite capital of the universe.
My undies are mostly moso, but when made into towels, outer garments, socks etc bamboo is mixed with other fibres in different proportions. Bamboo charcoal fibre, a product of nanotech, is becoming popular: sounds interesting, if a bit hyped.
If I did have scientific and technical capabilities, I’d hang with these guys. Love their work.
