Making
bamboo fiber constitutes using chemicals to process the bamboo pulp
into fiber. The process is similar to making rayon. Without outside
quality control, there's really no way of knowing if the bamboo fibers
are free of these chemicals, and/or that these factories are running a

process, and if you choose to buy bamboo fabric made from another
factory, you should make sure that they are certified.
