MADRID – A new study has calculated and compared the manufacturing water footprint of five types of textiles commonly used for the production of denim jeans. The study looked at spinning through the weaving and dyeing and focused on two different fibre types: cotton and Lyocell. It found that the overall water footprint of a pair of denim jeans made from cotton grown in Spain was double that of a similar pair of jeans made with 100% Lyocell.
