Intimate apparel and underwear maker Delta Galil has improved its RealCool Cotton fabric technology so that it is now more eco-friendly.

The fabric, which was launched in 2005 and combines wicking properties with the breathable comfort of cotton, is now treated with anti-bacterial and odour-repelling agents that are said to reduce the carbon footprint of clothing throughout its lifecycle.

By preventing the growth of bacteria, RealCool Cotton clothing requires less laundering and lower wash temperatures - thus reducing CO2 emissions.

"Underwear and hosiery are typically laundered at higher temperatures," says Esti Maoz, chief marketing officer at Delta Galil.

"The new treatment introduced in RealCool Cotton will allow the consumer to use more moderate temperatures, and at the same time extend the life of the product - both helping to protect the environment."
