Technologies to Reduce WEC

For over three decades, Cotton Incorporated has been at the forefront of facilitating innovations that help make textile manufacturing more efficient and effective. The World of Ideas presents practical and effective technologies for reducing the use of water, energy, and chemicals (WEC) in cotton textile processing, which is best achieved in fabric preparation, dyeing, and finishing processes. Using these solutions, the cotton textile industry can reduce the WEC environmental footprint by at least 50%.
