Development of Bio-based Nylon for use in Textile and Plastics Applications
Ajinomoto and Toray have announced that they will start a joint research for manufacturing bio derived nylon. The nylon will be manufactured from 1,5-pentanediamine (1,5-PD) from the amino acid lysine produced from plant materials by Ajinomoto by way of fermentation technology. Lysine is one of the nine essential amino acids which can not be synthesized by the body and food and other sources are the only mean to obtain it.
The manufacturing process will involve decarbonization of the amino acid lysine through enzyme reaction to make the 1,5-PD, which Toray afterward will polymerize with use of dicarboxylic acid.
The new material is expected to feature same strength and heat resistance as conventional nylon fiber made from petrochemical derived hexamethylenediamine. Furthermore, it is also capable of absorbing and desorbing 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.
