Toray will commercialize this textile in November 2020 for diverse applications needed to control unpleasant odors. They include use in innerwear, dress shirts, denim, chinos, and other regular apparel, as well as futon covers, sheets, and other bedding, and in work, service, medical, and school wear, and other uniforms. Toray targets initial sales of around 200,000 meters in fiscal 2021, increasing to 500,000 meters in fiscal 2025.

The company developed MUSHON with the Japan Aerospace Exploration Agency in 2008 to deodorize ammonia from perspiration. This material has won accolades for its performance in regular innerwear, uniforms, sportswear, and other items. MUSHON 4X augments the deodorizing capabilities MUSHON with odor suppression.

A rising number of sweltering summer days has increased the need to control and eliminate perspiration odors. Toray used its Technorama GII and Technorama GIII weather simulation chambers to reproduce a range of temperature and humidity conditions and reconfirm and assess odor causes. This work revealed the oxidative decomposition of sebum as an odor cause.

MUSHON 4X overcomes ammonia odors. It prevents stains by stopping sebum from accumulating in fabric. It suppresses the growth of bacteria causing mildewy odors. It also acts as an antioxidant in inhibiting the oxidative decomposition of sebum. Toray’s nanotechnology -based post-finishing treatment made it possible to deliver these benefits without harming washability. This general-use textile is suitable for diverse applications and can combine with sweat-wicking and stretch fabrics to enhance wearer comfort.
