dc.description.abstract In this study, a mixed bi-functional reactive dye and Mono-functional reactive dye was applied to the cotton fabrics. Their K/S values and wash fastness properties were compared. In the knitwear industry, the dyeing of 100% cotton knitted fabric is on the whole achieved with reactive dyes, due to the fact of their precise fastness homes and versatility of applications. The ease of application, vast coloration range, excessive brilliancy, and brilliant moist fastness residences make the reactive dyes desired preference for the dyeing of cellulosic fabrics. The most essential attribute of reactive dyes is the formation of covalent bonds with the substrate to be colored, i.e. the dye varieties a chemical bond with cellulose. Fiber reactive dyes are the most everlasting of all dye types. Unlike different dyes, it clearly types a covalent bond with the cellulose or protein molecule. Once the bond is formed, what you have is one molecule, as the dye molecule has emerge as an authentic section of the cellulose fiber molecule. From the results, it was observed that the 100% cotton knitted fabric K/S value very little increase in cotton fabric & little decrease in after applying finishing agent. Colorimetric value indicate that cotton batch fabric are lighter, reddish & yellowish than standard sample. But color difference value in both sample are acceptable. After applying finishing agent, the wash fastness (color change & Staining) of viscose fabric is better than cotton fabric. en_US
