Antibacterial activity has been imparted to nylon-6 by adsorption of iodine. Iodine adsorption has been carried out by two ways: a) dipping nylon-6 fibers into solution of iodine in acetone and b) exposing nylon-6 fibers to iodine vapours. The amount of iodine adsorbed has been found to be very high as compared to theoretical amount of iodine required to form single layer on the surface of fibers. Iodine adsorption from solution in acetone does not follow Langmuir adsorption, but adsorption in vapour phase appears to follow pseudo-Langmuir adsorption isotherm. In case of ...
