Ajinomoto and Toray to conduct joint research on biobased nylon

March 14/2012

(ajinomoto) -- Ajinomoto Co., Inc. ("Ajinomoto") and Toray Industries, Inc. ("Toray") have entered into an agreement to begin joint research for manufacturing the nylon raw material 1,5-pentanediamine (1,5-PD) from the amino acid lysine produced from plant materials by Ajinomoto using fermentation technology, and commercializing a biobased nylon made from this substance.

Biobased nylon is a type of nylon manufactured by polymerizing chemicals produced from plant materials. The biobased nylon that Ajinomoto and Toray will research and develop is produced from plant materials by decarbonating the amino acid lysine through an enzyme reaction to make 1,5-PD, which Toray then polymerizes with dicarboxylic acid.

The amino acid lysine is a core product of the Ajinomoto Group produced using fermentation technology. This biobased nylon fiber made from 1,5-PD is not only sustainable because it is plant-based, but also shows promise for development into highly comfortable clothing. For example, nylon 56 fiber manufactured using 1,5-PD is pleasing to the touch, yet has the same strength and heat resistance as conventional nylon fiber made from the petrochemical derivative hexamethylenediamine. It also absorbs and desorbs moisture nearly as well as cotton.


The two companies have already carried out successful test production of 1,5-PD using Ajinomoto's feed-use lysine, as well as test production of biobased nylon made by polymerizing 1,5-PD. They plan to further expand the scope of their collaboration to include development of production processes and evaluation of use in textile and plastics applications.
