MASSACHUSETTS – A team of scientists at MIT (Massachusetts Institute of Technology) has developed a new coating for natural fibres which it claims can improve the functionality of, and perhaps most vitally, combat the environmental persistence of current water-repellent coatings.

The study has been motivated by the fact that the EPA (United States Environmental Protection Agency) is currently considering proposals to revise regulations surrounding long-chain polymers due to the way conventional chemicals used in water-repellent textile treatments accumulate in the environment and body tissue.
