Toray, the Japanese developer of polymers, is planning to show a new polyamide fiber that can be produced from renewable resources at Ispo. It follows the company's announcement last June of the first polyester fiber that is 100 percent based on biomass. Toray will be categorizing its new fibers, fabrics and laminates as “hybrid engineering” at Ispo. Toray uses the castor plant for its biomass. Castor grows bountifully in dry areas, it can be harvested several times a year, and its resistance to pests means it requires less pesticides and herbicides than other crops.
