Influence of different parameters on dyeing of knitting material with reactive dyes

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/dm3.Nasa ispitivanja se odnose na efekte razlicitih parametara na proces bojenja pletenog materijala reaktivnim vinil-sulfonskim bojama. Na osnovu odgovarajucih korelacija parametara, data je ocena valjanosti primene ultrazvuka u procesu bojenja tekstilnih supstrata od pamuka. Zeljeni ton boje moze se postici primenom ultrazvuka uz smanjenje koncentracije boje ili skracivanje vremena bojenja za 20 min sa istovremenim smanjenjem koncentracije soli cak do 20 g/dm3.
