The procedure was performed using poly(lactic-acid-co-glycolic-acid), PLGA, and polyvinyl alcohol, PVA, and was confirmed via optical microscopy. UV-VIS spectroscopy assessed the efficiency of the encapsulation; and, the mathematical models of Korsmeyer-Peppas and Higuchi quantified controlled-release of dye. The microcapsules formed a core-shell structure, with a perfect sphere shape and homogeneous size. The release adjustments yielded the apparent diffusion coefficient.</p>}, month = {7}, pages = {6}, keywords = {Reactive Dye,microcapsule,solvent evaporation}, publisher={}, journal = {Proceedings of the 19th World Textile Conference - Autex 2019} }
