Disperse dyeing effected by ph

For disperse dyeing the dye bath should be acidic and p^h should be maintained in between 4.5 -5.5 . For maintaining this p^{h generally acetic acid is used. We may also use any mineral acid like H}₃ PO₄ but those are strong andcostly. So mild acid likeacetic acid is used for controlling p^h   of the bath. At this p^h  dye exhaustion is satisfactory. During color development correct p^h should be maintained otherwise fastness will be inferior and color will be unstable.
