Urea,as dye disaggregation and solubilizing agent,plays an important role in direct printing process,though it has negative environmental impact due to ammonia nitrogen emission.Not only cotton reactive dye printing involves application of urea.Also disperse dye print pastes consists of it,mainly applied by'professional artists and designers.In this study,the possibility of urea replacement with polyethylene glycol(PEG)for polyester fabric printing was examined.The action of glycerine,as additional dye dissolving agent,was also explored.With variation of urea and PEG concentration(25,50 and 100 g/1000 g paste),and addition of glycerine(20 g/1000 g paste),an impact on results of colour measurements and fastness was analysed.With application of PEG to polyester printed fabrics higher colour fastness to washing and artificial light can be obtained.
