Seawater as a viable alternative in cotton dyeing

A recent study published in Coloration Technology reveals that despite its high mineral content, seawater can replace up to 70% of freshwater in cotton fabric dyeing without compromising colour quality or durability.

Led by Iêda Letícia de Souza Ferreira and her team at Universidade Federal do Rio Grande do Norte, the research marks a significant step toward sustainable textile manufacturing, especially in regions facing freshwater scarcity.
