INFLUENCE OF DIFFERENT PARAMETERS ON DYEING OF KNITTING MATERIAL WITH REACTIVE DYES UDC 676.088.48: 547.44

Abstract. Our studies concern the effects of different parameters on dyeing process of knitting materials with reactive vinyl sulphonic dyes. Based on the corresponding parameters correlations, an estimation of ultrasound application validity in dyeing processes of cotton – type textile substrates has been established. Desired color hue may be attained with application of ultrasound reducing dye concentration or shortening dyeing time for 20 min with reduction of salt concentration even to 20 g/dm 3.
