Prior to dyeing process, there are certain vital pre-treatment processes that must be given to fabrics. One of which is the scouring of fabrics with detergents. These detergents are known as amphiphathic substances. However, it needful to determine the effectiveness of these detergents used in scouring fabrics by measuring the dye-uptake of the textile material scoured with these detergents during dyeing process. This was done by the use of seven (7) selected Nigerian domestic detergents of known chemical constituents. The cotton and the baft textile sample swabs of 50 cm X 50 cm dimension (7.1g + 0.2) was pre-washed with Nittol, Virony, Ariel, Omo, Zip, Waw and Sunlight detergents of known concentration and goods to liquor ratio of 1:50. These textile swabs were rinsed for 5 times and oven dried at 50°C. Then the pre-mordanting treatment was done to enhance optimum dye absorption of the textile substrates through the use of 1% commercial alum. Each washed textile sample swabs was stepped into the mordanting liquor at 27°C. The wave scan and the calibration curve of the dye stuff used (Plant pigment: Pigment Vegetal) was determine using the UV-Visible spectrophotometer. Each dye bath of known concentration (0.29/100ml) was prepared for dyeing the textile swabs and the percentage dye uptake was determined alongside the control textile (textile swabs not washed without detergent), for a dyeing duration of 1-20 min. The baft textile samples generally have higher dye uptake value than the pure cotton. However, out of seven detergents, only Virony (48.91%) and Omo (52.14%) have the highest dye uptake at 360 and 180 seconds respectively.
