Nylon 6.6, Amni Soul Eco (Solvay Group, Brazil - contains data for yarn formation/spinning)

Amni Soul Eco is composed of an enhanced polyamide 6.6 formula, developed by the research efforts of the Rhodia-Solvay group, which enables garments to quickly decompose when they are discarded and left in landfills.In anaerobic landfills, its unique composition allows bacteria to gain access to and digest the waste materials, thus accelerating the biodegradation process to about 3 years, whilst other fibres take decades to decompose. Like other biodegradable products, once it is in the landfill, Amni Soul Eco®, breaks down into organic matter (biomass) and biogas; both of these can then be exploited as new environmental resources as well as being used to cogenerate electricity.
