Clothing and yarn made from the fiber, Bambu, is gaining popularity as an environmentally friendly alternative to cotton. The fiber is made from the renewable plant, bamboo.
As a botanist, I know that that bamboo doesn't have the kind of plant fibers (aka "natural fibers") that are present in hemp, cotton, or linen. These are individual cells that can, in some cases be many inches long:
Clearly there is VERY LITTLE DIFFERENCE between Bambu and good old fashioned Rayon!! Rayon (aka Viscose) is made from wood chips. In both cases, the chopped plant material is boiled in lye until it literally dissolves. Then the liquid cellulose that results is forced through spinnerets like this. You can read more about the process, here.
As best I can tell, there's nothing organic about this fiber! So don't be Bambu-zled!!
