Mukilteo

The Japanese yarn manufacturer that supplied Mukilteo's yarns developed a new viscose1 production method to turn the bamboo into yarn that has a substantially lighter environmental footprint than previous viscose production processes. Manufacturing viscose requires the use of a sulfuric acid bath; so, although the resulting yarn is non-toxic (ours is Oeko-Tex 100 certified, and safe enough to eat), the waste could create an environmental hazard. Our manufacturer uses bacteria and enzymes to neutralize the sulfuric acid and thereby returns wastewater to the ecosystem that meets stringent Japanese drinking water standards. There is some outgassing of the sulfuric acid to the air, air pollution. As demand for our bamboo grows, our spinner will be able to afford to address this issue as well. All in all, even with the slight outgassing into the air, we believe bamboo is a very important addition to the world's textile set. A dedicated conservationist owns the small mill in Japan where thes
