The laboratory needs to determine how the key process parameters have to be adjusted in order to maximise dyeexhaustion.
为了是上染率最高，实验室需要判定如何调整生产过程中的关键参数。

I. Direct Black 38. Similar dyeexhaustion curves, color shades and dye depths, dye processing as well as absorption spectra were shown.
直接黑38进行了比较，结果显示：这些染料在上染曲线、染色深度、染色工艺、可见光谱和染料色光与C。

It would be possible, but time consuming, to make numerous laboratory dips for a certain colour using different key parameter values and then compare the dyeexhaustion.
