Objectives: The objective of the study is to analysis the effect of chemicals on different physical properties and color fastness of treated cotton samples with standard rating values. Methodology: Five single baths are used for the pretreatment process with five different dosages such as 1g/L, 1.5 g/L, 2 g/L, 2.5 g/L, 3 g/L of NaOH and H2O2. After that, reactive dyeing was performed for these five samples with a standard recipe. Findings: With the gradual increment of NaOH and H2O2 dosages, the absorbency and whiteness index of pretreated samples were improved and for that particular reason bursting strength was degraded. On the other hand, for dyed samples, a little variation was observed in color fastness to wash and rubbing but the changes in the color shade of every sample were observable.
Keywords: Bleaching; color fastness; physical properties; scouring; shade variation
