The aim of the research work was to investigate knit fabric weight loss in combined scouring and bleaching with 35% concentration of hydrogen peroxide and 30% concentration of hydrogen peroxide. Theresearch was conductedin knit fabric manufacturing sector and worked on fabric pre-treatment process. It was taken about two months to work on these findings. The pre-treatment of the cotton fabrics involves improving the absorbency and the whiteness of textile materials, removing from the fibres the non-cellulosic natural matter, i.e., fats, waxes, pectins and proteins. The hydrophobic properties of raw cotton are enhanced by waxy materials and pectins. Caustic soda is used to remove pectin substances and cotton wax contained in knitted fabrics. Pre-treatment of fabric was followed by dyeing.This work aims on the determination of the pre-treatment performance on the basis of scouring and bleaching in combined stage. Cotton fabrics were pre-treated with combined scouring and bleaching with different concentration of hydrogen peroxide. After the operation, the pre-treatment performance was measured in terms of fabric weight-loss percentage. It was noticed that the higher concentration of hydrogen peroxide results inferior impact on knitted fabric compared to less concentration of hydrogen peroxide recipe.
