Focus on High-Performance Products
Polyester fibers have evolved as the Teijin Group's core business, in line with growth in the global market. Today, the Group boasts a wealth of products for applications in various industries, from apparel to industrial materials, such as those used in automobiles and aircraft.
Since its establishment, the Teijin Group has amassed a vast array of polyester-related technologies. By drawing on these technologies, together with its experience and expertise in all aspects of the polyester fibers business, from development to sales, we are advancing a business strategy that emphasizes high-performance products.
Spearheading Efforts to Address Environmental Issues
Harnessing our topflight polymerization technologies, we have developed the world's first chemical recycling technology for end-of-life polyester products. As part of our efforts to address environmental issues, we are actively developing and marketing environment-friendly products that capitalize on this technology in markets around the world.
We are also striving to expand sales of environment-friendly products, including "PURITY", a heavy-metal-free polyester material, and "BIOFRONT", a heat-resistant polylactic acid (PLA) fiber. "PURITY" is produced using a proprietary titanium-based catalyst that is completely free of heavy metals, which exert a considerable impact on the environment.
Innovative Technologies, Products and Systems
We are concentrating efforts on maximizing the innate advantages of materials to develop new applications, as well as high-value-added and groundbreaking products, that respond to the needs of customers in global markets. In particular, we are leveraging our strengths to develop environment-friendly products and revolutionary high-performance materials, as well as to build businesses centered on such consumer products as insect-repellant apparel and screen speakers.

Outline of Operations
Polyester Fibers
Valued for their strength, excellent chemical resistance and ease of care, polyester fibers now account for approximately 80% of all synthetic fibers produced worldwide. Often thought of as primarily for use in apparel, polyester fibers add value to a broad range of products, including mattresses, rubber reinforcements and filters, a fact that is reflected in the massive volume of these fibers produced worldwide.
"ECO CIRCLE" Closed-Loop Recycling System
"ECO CIRCLE" is a closed-loop recycling system for used polyester products that employs the world's first chemical recycling technology. With this technology, polyester is chemically decomposed and converted into new polyester raw materials of comparable purity to those derived from petroleum. We cooperate with registered participating apparel and sportswear manufacturers in Japan in the development and manufacturing of products made from recyclable materials and in the collection and recycling of these products at the end of their useful lives. Leading U.S. outdoor gear manufacturer Patagonia, Inc., has also adopted "ECO CIRCLE" for its garment recycling program, marking the first step toward expanding the network of companies worldwide participating in the "ECO CIRCLE" scheme.
In 2005, the "ECO CIRCLE" system received a Good Design Award in Japan in recognition of its innovative concept and potential for contributing to a recycling-oriented society.
Advanced Technology—Based Solutions
In addition to our polyester-related technologies, we are using nanotechnology to develop innovative products that anticipate emerging market needs. Among these are such groundbreaking offerings as "MORPHOTEX", a structurally colored fiber; Moisture Responded Transformable (MRT) fiber, a selfregulating fiber; and "BEWELL", a fiber with durable and antistatic properties.
The Teijin name is also associated with polyethylene naphthalate (PEN) fibers. Valued for their excellent strength and heat resistance, these fibers are increasingly in demand for automotive and other applications requiring these properties.
