Abstract The study comprises the effect of different bleaching parameters on scoured single jersey cotton fabrics. Three different concentrations 1.8 gL 2.0 gL and 2.2 gL taken from 5 stock solution of hydrogen peroxide were considered for the experiment. In each concentration bleaching was performed in four individual temperatures 78C 88C 98C and 108C. In each of the temperatures bleaching were continued for four individual time period 20 30 40 and 50 minutes. The weight of sample fabric was 12.5 grams and 110 liquor ratio was maintained in each operation. The bleached samples were tested in a reflectance spectrophotometer datacolor 650 and also their bursting strengths were found from an Autoburst instrument following ISO 13038-1 method. The results show that bursting strength and whiteness index have an inverse relation between themselves. For the nominated concentrations of peroxide 88C to 98C temperature with 30 to 40 minutes time duration is suggested as the optimum bleaching parameter for knitted cotton fabric.
