Description
Lili Feng and four co-authors dye a biodegradable fabric at lower temperatures using a natural solvent bath and a microbe made pigment, in this 2026 study. The fabric, woven from polylactic acid, is kind to the planet but normally needs hot dye baths that weaken its fibers. The pigment, prodigiosin, also kills bacteria, which adds a bonus function.
A bath of glycerol and citric acid roughened and loosened the fibers, letting dye slip in more easily. Treated fabric dyed at seventy degrees matched the color depth of untreated fabric dyed at ninety. It also stopped over ninety-three percent of a common skin bacterium in tests. The authors present the recipe as a greener route for sustainable textiles that keeps strength and adds hygiene.
