Sustainable Pigment from Cotton-Rich Textile Waste for Interior Wall Painting
Growing ecological awareness and concerns over conventional coating toxicity drive the demand for sustainable alternatives. This study presents a strategy to upcycle cotton-rich textile waste into biopigment powder (D50 = 5.37 μm, SSA = 8.21 m2/kg) via optimized low-energy milling. Incorporated into water-based acrylic coatings, the powder demonstrated exceptional photostability (ΔE = 2.61 after 10-h simulated sunlight irradiation, 300 W) and prominent water resistance (ΔE < 0.8 after 72 h immersion), attributed to superior powder–paint compatibility and effective shielding by the cured polymer layer. Omitting energy-intensive spray drying reduced production costs by 55.41%. By integrating waste valorization with particle engineering, this work establishes a scalable circular economy strategy addressing textile waste recycling and sustainable coating development simultaneously, creating opportunities for eco-smart architectural materials.
