Today’s portfolio of commercially available biosynthetic fibers includes PLA (Polylactic Acid), partially biobased PTT (Polytrimethylene Terephthalate), partially biobased PET (polyester), PA11 (Nylon/Polyamide 11) along with a number of bio alternatives to PA6,10, PA10,10 and PA10,12.
Companies are also working on developing new technologies for commercially producing biobased aromatic chemicals – the basic building blocks for making both nylons and polyesters for apparel – from renewable feedstocks. Successful scale up and commercial production of these biobased chemicals would enable future production of 100% bio based synthetic polymers.
