Curious about bamboo fiber production, I Googled that for info. Here are a couple of excerpts from just one site: "Bamboo cultivation requires zero pesticides or chemical fertilizers to achieve its amazing growth rate and renewability. Hence, it is inherently organic. In addition, bamboo requires much less land and water (as a ratio to usable fiber produced per acre), than cotton, organic cotton, and other alternative fibers." "Chemicals are used to get cellulose (viscose) from bamboo, but by far the principle chemical used is sodium hydroxide (i.e., lye). Sodium hydroxide is one of the most widely used chemicals in the world and has no negative effect on the environment or the health of humans. Sodium hydroxide is routinely used in the processing of cotton into fiber, including transitional and organic cottons, and is approved for use on textiles by the Global Organic Textile Standards (
www.global-standard.org) and the Soil Association (
www.soilassociation.org). Sodium hydroxide does not remain as a residue on clothing as it easily washes away."
