Toray Industries, Inc. has developed the antiviral textile MAKSPEC V.

Toray Industries, Inc. has developed MAKSPEC V, an antiviral textile that delivers exceptional washability and comfort. This polyester material is the fruit of proprietary textiles processing technology that ensures the durability of antiviral processing while providing a soft and comfortable texture. The antiviral properties of MAKSPEC V reduce the lipid bilayer envelopes of viruses on the material.

Toray aims to propose an array of applications that take advantage of these features. These extend from service, medical, work, school wear, and other uniforms to sportswear, casual apparel, and fashion wear.

The company will commercialize MAKSPEC V textiles in January 2021. It targets 300,000 square meters in sales in 2022, rising to 1 million square meters in 2025.

Toray resolved these issues by using optimal antiviral agents and leveraging a proprietary fixation technique for polyester fibers. Because of its ability to reduce envelope strains, MAKSPEC V accordingly received certification under the SEK Mark program of the Japan Textile Evaluation Technology Council as an Antiviral Finished Textile Product.

MAKSPEC V also offers good commercial laundry washability, maintains textile softness for wearer comfort and enables the colorfastness needed for fabric in regular apparel.
