Technical Abstract: In this study, the effect of morphological integration of silver nanoparticles to cotton fiber—interior versus exterior—on silver release during consecutive washings was studied. The interior silver nanoparticles were produced by in situ synthesis within cotton fiber, whereas the exterior silver nanoparticles were produced by the pad-dry method of silver colloid onto a cotton fabric. A combination of analyses, including surface-enhanced Raman spectroscopy, inductively coupled plasma mass spectrometry with ultrafiltration, ion-selective electrode method, and UV/Vis spectroscopy, showed that the release of ionic and particulate silvers strongly depended on the mode of integration during washing. The interior silver nanoparticles predominantly released ionic silver rather than particulate silver, and the amount of silver released was much smaller than that from the exterior silver nanoparticles. This leach resistance of the interior nanoparticles was attributed to their immobilization within cotton fiber.
