Sažetak
Istraživanje je vršeno nad tkanom pamučnom materijalu obojenom vrstom naradžaste (Procian Orange M2R, dobro rastvoriva), plave (Procian Blue Herd, slabo rastvoriva), vinil sulfon reaktivnom bojom, (Remazol boja), a analizirali smo postojanost boje sa različitim koncentracijama sode 5g/l, 10g/l, 15g/l, 20g/l, i 25g/l, gde je temperatura bila ista, odnos rastvora i materijala, vreme i koncentracija soli. Došli smo do toga da povećanje koncentracije sode nema uticaja na postojanost boje prilikom trenja, perspiracije i pranja pamučnog materijala koji je obojen reaktivnom bojom. Ipak, ustanovili smo da se povećava postojanost boje sa povećanjem koncentracije sode za boje koje se dobro rastravaju, slabo rastvaraju i vinil sulfon reaktivne boje. Razlog je verovatno to što je fiksiranje boja bolje kod celuloznih vlakana (tkan pamučni material) zbog jakih kovalentnih veza.
Abstract
An investigation was carried out on woven cotton fabric dyed with Procian Orange M2R (cold brand), Procian Blue Herd (hot brand), Vinyl Sulphone reactive dye (Remazol dye) to analyse the fastness properties at different soda concentrations such as 5g/l, 10g/l, 15g/l, 20g/l, and 25g/l keeping temperature, material to liquor ratio, time and salt concentration as constant. It has been found that there is no effect of increase in soda concentration on the colour fastness to rubbing, perspiration and washing of cotton fabrics dyed with reactive dyes. However, it has been found that relative percentage color strength increases with increase in soda concentration for cold brand, hot brand and Vinyl Sulphone reactive dyes. It may be due to the better fixation of dyes with cellulose fibre (woven cotton fabric) by strong covalent bonds.
