  Abstract:  

In this paper were analyzed and interpreted the colour characteristics of dyed samples, based on remission curves. The correlation between the remission dying and the dyes concentration, for wool dyeing with acid dyes was also studied.There have been dying with two acid dyes on 100% wool fabric, six levels of concentration, ranging between 0,1% - 2,0%, in specific conditions of wool dyeing with acid dyes.Remission curves were drawn for two dyes: red and yellow and mixtures of two dyes take in equal parts, in the visible spectral domain. Based on these remission curves, were analyzed and interpreted the following: the colour characteristics for dyed samples, the correlation between remission colour and the concentration of dyes and the interaction between the dyes in mixing pain.

Keywords: remission, acid colorants, wool texture, visible spectral domain, dyeing, concentrations, colours characteristics.
