Teijin Cordley Develops Antibacterial and Antiviral Artificial Leather
Tokyo, Japan, September 28, 2021 --- Teijin Cordley Limited, the Teijin Frontier Group's
high-grade artificial leather business, announced today that it has developed a new
antibacterial and antiviral (*1) artificial leather incorporating long-lasting antibacterialagent.
(*1) antibacterial and antiviral: not effective against all bacteria and viruses.

Teijin Cordley will commence sales of the new artificial leather in October this year; initial
versions will be designed for the manufacture of children’s satchels; subsequent versions
will additionally be suitable for sporting goods such as shoes and leather balls. The sales
target is 30,000 meters in fiscal 2021 and 580,000 meters in fiscal 2024.

Antibacterial and antiviral artificial leather

Leveraging Teijin Cordley’s unique surface treatment technology, the new antibacterial
and antiviral artificial leather can be treated with the same process as conventional
artificial leathers such as natural-like, enamel and nubuck artificial leathers, and can beused in a wide range of applications. In addition, products using the new leather material
can be classified as “environmentally friendly”, as it is created using recycled polyester
raw materials. The long-lasting antibacterial agent on new artificial leather’s surface has
led it acquiring SIAA (*2) antibacterial processing and SIAA antiviral processing
certification.
(*2) SIAA: The SIAA brand mark is borne on products under quality control and information disclosure by theguidelines of the Society of International sustaining growth for Antimicrobial Articles

The technology in the long-lasting antibacterial agent was originally developed to control
the growth of microorganisms such as mold in the confined spaces of submarines, and iseffective against various kinds of bacteria, mold and viruses. In addition, it has thepotential to treat a variety of materials such as fibers and hard materials, and has beenused in applications including apparel, rush products, and humidifying filters for airpurifiers.
The spread of COVID-19 has enhanced general interest in infection control in daily life,
and the need for antibacterial and antiviral processing is increasing. There is also
increased focus on the need for hygiene measures during sporting events. Antibacterial
and antiviral processing technology for general textile products has been developed forpractical use; however, it is difficult to maintain the antibacterial and antiviral properties
when these are processed into artificial leather.
