Abstract

Microencapsulations protects the dye molecule from secondary reactions and release until contact with the fiber, triggered by stimuli. 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.

Keywords: Reactive Dye, microcapsule, solvent evaporation
