The aim of this study is to compare the effects of coumarin and stilbene based optical brightener agents on the cotton textile. To achieve this aim, the cotton textile is being died at several concentrations of coumarin and stilbene based optical brightener agents. Then the washing, sizing and bleaching processes are done for the cotton textile. It is concluded that the fastness of the coumarin based optical brightener agents is more significant than stilbene optical brightener agents.
