Dyeing is a method which imparts beauty to the textile by applying various colors and their shades on to a fabric. Dyeing can be done at any stage of the manufacturing of textile- fiber, yarn, fabric or a finished textile product including garments and apparels.
Dyeing is a process in the conversion of raw textile fibres into finished goods that add much to the appearance of textile fabrics.
Factors considered in dye selection include fastness to light, reaction to washing and rubbing (crocking), and the cost of the dyeing process. Effective preparation of the material for dyeing is essential.
The principles of a dyebath monitoring technology that allow the analysis and control of the dyeing process are introduced. This measurement technology can aid in troubleshooting root causes in shade reproducibility that can occur from variability in dye strength, the fabric or the dyeing process.
