Combinedmodifying anddyeingof the treated fabric samples resulted in a sig-vailable online 21 September 2010 eywords: olyamide/cotton blend odification nificant improvement in the extent of coloration along with a remarkable improvement in the imparted functional properties namely UV-B protection and antibacterial function. The change in K/S value as well as in the fastness properties ratings of the obtained dyeings along with variation in their functional properties depend on the ester-crosslinker/catalyst concentration, type and concentration of the coloring agent aswell as thermo-fixation temperature.Modeof interactionwas reported, and surfacemodification M an asic dyeing igment dyeing unctional finishing was also confirmed by SE .
