Cotton fabrics were modified by different methods such as oxidation, sulfonation and crosslinking processes. The modified and unmodified fabrics were subjected to weight measurements, water absorbency and strength tests. In SEM analysis, modified fabrics showed improved woven pattern with less protruding fibres in x 75 magnification and swollen smooth rod like appearances in x 1500 magnification than in unmodified fabrics. Modified fabrics were dyed with Reactive Red 120 and Direct Blue 86 under alkaline condition with low salt content. The modified fabrics showed improved dye uptake than unmodified fabric. Crosslinking modification was found to be very effective than sulfonation modification. Dye uptake and wet fastness properties were improved for modified fabrics. For a 0.5% dye concentration study, the dye uptake obtained for modifications is ranked as UM < 1W < 2W < 4W < 3W in reactive dyeing and UM < 1W < 4W <2W <3W in direct dyeing.
