Reuse color difference calculation

Table XXVII. Dyebath Reuse Color Difference Calculations 100% Cotton/One Low-Temperature Reactive Dye...

The dyed nylon batches were evaluated by color measurement and color difference calculations using the described procedure. Ten random samples were cut from each of the five nylon carpet sections (3 x 38 ) dyed in the reuse sequence. Color differences between the samples from the four reuse runs and samples for the initial (conventional) dyeings were calculated. The tristimulus values and 1 were obtained on the Diano... 

Reproducibility of the dyeings was determined by calculation of the color differences between dyed lots and a standard dyeing of the same shade. In this calculation the color difference was determined from average tristimulus values of each dyed lot compared to a conventional dyeing, again using the FMC II equation. In addition to instrumental measurements, samples dyed by the reuse procedure were examined visually by expert dyers to further assess the color uniformity and color reproducibility.
