Reactive dyes are one of the most popular dyes for cotton goods and other cellulosic fibres. The main investigations for application of reactive dyes for cellulosic fibres are devoted to cotton textiles. In this paper the research results of investigation of colour properties, colour and rubbing fastness, mechanical properties of pre-modified with alkali and enzyme linen fabric dyed with colour triad of Cibacron reactive dyes are presented. The investigation results show that the main factor influencing the colour properties of linen fabric dyed with examined reactive dyes is used dye. The modifiers use increases the rubbing fastness of dyed linen textile. The modifiers influence on colour and colour properties before and after light test is selective for used dye, but not significant.
