In textile dyeing application one has to produce consistent lots of dyeing. Colour measurement technique helps us to quantify colour in terms of numerical values. The need for a numerical pass/fail program arises from the fact that visual evaluations of shade difference are not consistent when establishing the fine line between acceptable and unacceptable dyeing. In this chapter, we will discuss the role of colour measurement in textile application with reference to colour measurement techniques, acceptability limits for pass or fail, importance of spectral match, use of on-line and non-contact colour measurement systems, colour of dry and wet fabrics, and inspection of colour of finished fabrics. |
