Self-cleaning fabric could eliminate the need for detergent Detergents may begin their journey by cleaning our clothes, but they end up contaminating the environment, flowing into rivers, ponds, and oceans, where they severely disrupt aquatic animal life. Even after wastewater treatment, some chemicals remain and pass through filtration systems, continuing to pollute natural water bodies. A team of researchers from China explored the question: What if our clothes could be washed without detergent? In a study published in Communications Chemistry, researchers introduced a versatile self-cleaning fabric coating that could eliminate the need for detergents in everyday laundry. By alternately spraying the fabrics with two polymers—poly(diallyldimethylammonium chloride) (PDADMAC) and poly(vinylsulfonic acid) (PVS)—they created a dense hydration layer that allows dirt and microbes to be washed away using only water. The coating remained effective for over 100 wash cycles. It made laundry quicker and reduced water and electricity consumption by ~82%. Source:Phys.org @EverythingScience
