Printing of polyester cotton fabrics by one paste of disperse and reactive dyes

This paper investigated the printing of polyester/cotton fabrics by one paste of disperse and reactive dyes in respect of dye selection,the impact of drying temperature,curing time and temperature,urea and alkali consumption on the fixation rate of the reactive dye,as well as the effect of surfactant on anti-staining.The optimum technology was determined.The experimental results revealed that employing proper dyes and curing process can render the printed fabric with good color fastness and fixation rate of both disperse and reactive dyes.Washing with mixed alkali water containing Peregal O and anti-staining agent can very well prevent staining to white ground.This process can meet the requirements of practical production.
