ABSTRACT = {The present work is focused on the study of antimicrobial and water absorption properties of
the surface of grafted rayon fiber with quaternary ammonium-based salts containing 3-
Acrylamidopropyl trimethyl ammonium chloride (APTAC) monomer induced by gamma radiation.
Grafting was qualitatively confirmed by FTIR-ATR,TGA, SEM and by calculating grafting yield
and grafting efficiency. The performance was examined for water absorbency and antibacterial
efficacy (R) against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus). Study
showed that water absorption, grafting yield and grafting efficiency increased steadily with the
increase in monomer concentration and absorbed gamma irradiation dose up to a certain level
followed by either slowdown or leveling off the increasing trend. The water absorption and
antibacterial efficacy (R) of the APTAC-grafted rayon fiber was found to be substantially enhanced
as compared to pristine rayon fiber showing a remarkable 435% increase in water and a four log
cycle decrease in the number of living bacteria after 24 hours of incubation.},
