Study on effect on concentration of Soda on dyeing of woven cotton fabric with Reactive dye

Abstract

Cotton is a natural fiber and it is a cellulosic fiber. Reactive dye is most commonly used for cotton dyeing. It is used to dye wide range of shades like light shades to dark shades of cotton fabric. The aim of our work is to observe the effect of dyed sample when we change the concentration of soda in the solution. Here we conceder three different concentration of soda 20 gm./l, 15 gm./l &10 gm./l. One thing we carefully considered that the entire three samples are similarly processed and the fastness properties like color fastness to wash; color fastness to rubbing is strictly controlled. Then we observed the depth of the shed with the help of data color software (CCMS).
