Direct Dyes are molecules can adhere with fabric molecules without any help from chemicals. It is anionic dyes with good substantivity for cellulosic fibers. This study attempts to investigate impact salt, M:L, Na2CO3 on knit fabrics (cotton and viscose cotton blended) dyeing by using direct dyes. Although a large number of research works have been accomplished in this field, a significant investigation still required. Research findings state that the absence of Salts and Soda Ash decrease the overall dye take-up as well as decrease of Material: Liquor increases the dye absorption or take-up of the knitted sample. Also, viscose cotton blended specimen shows less dye absorption and overall lower result comparing cotton.
