Teijin Cordley develops antibacterial and antiviral artificial leather – nonwoven industry magazine

Teijin Cordley Limited, the high-quality artificial leather business of the Teijin Frontier group, has announced that it has developed a new antibacterial and antiviral artificial leather incorporating a long-lasting antibacterial agent.

Teijin Cordley will begin sales of the new artificial leather this month; initial versions will be designed for the manufacture of children’s schoolbags; later versions will also be suitable for sporting goods such as leather shoes and balls. The sales target is 30,000 meters for fiscal year 2021 and 580,000 meters for fiscal year 2024.

Taking advantage of 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, glazed and nubuck artificial leathers, and can be used in a wide range of applications. In addition, products using the new leather material can be classified as “environmentally friendly” because they are created from recycled polyester raw materials. The long-lasting antibacterial agent on the surface of the new artificial leather has led it to acquire the certification of SIAA antibacterial treatment and SIAA antiviral treatment.

Artificial leathers are made by impregnating a non-woven fabric substrate and coating with a resin such as polyurethane. Cordley artificial leathers have a layer of fibers with a random three-dimensional conformation which is very similar to that of natural leather.

Long-lasting antibacterial agent technology was originally developed to control the growth of microorganisms such as mold in confined spaces of submarines, and is effective against various types of bacteria, mold and viruses. . In addition, it has the potential to process a variety of materials such as fibers and hard materials, and has been used in applications such as clothing, urgent products, and humidifying filters for air purifiers.

The spread of Covid-19 has heightened the general interest in infection control in everyday life, and the need for antibacterial and antiviral treatment is increasing. There is also increasing emphasis on the need for hygiene measures at sporting events. Antibacterial and antiviral treatment technology for general textile products has been developed for practical use; however, it is difficult to maintain the antibacterial and antiviral properties when made into artificial leather.
