During the dyeing process, the dye must become close and even with the material in order to produce a uniform color that is fast to moisture, heat, and light. [5] Due to their superior fastness properties and simple application, reactive dyes are currently the most common type of dye for cotton dyeing. [6] The CPB technique uses less water and ...
The planting season is from September to mid-November, and the crop is harvested between March and June.

The like charges repel each other, and the addition of salt aids in dyeing by generating a positive charge on the cotton surface. [7] [8] The industry has predominantly used reactive dyes to color knitted cotton goods. The treatment of salt-laden, colored effluent generated by the dyeing process is one of the industry's primary concerns. Cotton ...
