【 摘 要 】

Reactive dyes have proven to be one of the most commonly applied classes of modern synthetic dyes. Unlike other dye classes for cellulosic textiles dyeing and printing, the reactive dyes provide excellent wash-fastness for a very wide shade gamut. One of the most important components of print paste, especially for reactive dye printing of cellulosic textiles, is urea. Despite urea's great importance in adjustment of dye distribution in the paste, it can cause environmental problems. In this study, the application of polyethylene glycol (PEG) (10, 30 and 50 g/100 g) was examined for urea's replacement in reactive dye print paste. The optimal concentration of sodium bicarbonate, as pH buffer, was found. Testing results of colour fastness and colour measurements approved PEG application possibility.
