Kuraray Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; President: Yasuaki Wakui) announces the development and subsequent marketing of the TIRRENINA brand of next-generation, eco-friendly man-made leather, which combines the appearance and texture of natural leather with the superior functionality unique to man-made leather.
Amid heightening concern surrounding environmental issues, Kuraray introduced an innovative new process that does not utilize organic solvents in the production of TIRRENINA , succeeding in significantly reducing emission volume of organic solvents. In addition, Kuraray overcame the stiff texture often seen in water-based man-made leathers made with inorganic solvents, employing newly developed production processes and ultra-fine fibers to give TIRRENINA a texture, fullness and attractive appearance close to that of natural leather.
This year marks Kuraray's 40th year as the pioneer and top manufacturer of man-made leather, beginning with the study of natural leather and sales launch of CLARINO in 1965, a cutting edge material at that time. Kuraray's man-made leathers have received high marks and support in a variety of markets. CLARINO men's shoes gained notice when the "duck" television commercial advertising the shoes became the talk of the times. CLARINO schoolbags are loved by the many fans they have won over many years. AMARETTA is a variety of man-made leather with the look of high-grade suede, and is used in a variety of fields including apparel, interior and bags. Other man-made leathers include FLORISSIMO, a pressed soft material, and PARCASSIO, which incorporates some of the processes used on natural leather.
Kuraray has positioned TIRRENINA as next-generation, eco-friendly man-made leather, and will work to introduce this innovative new product on a global scale. We will continue to make advances in technologies related to fibers, nonwoven fabrics and finishing processes, and to provide highly original new materials with a pervasive presence in everyday life through wide applications in shoes, bags, sporting goods, apparel, interior and car seats.
