Abstract

U završnom radu pod naslovom „Tekstilni tisak prirodnim bojilom košenil ekstrahiranim iz Dactylopius coccus“ proveden je tisak vunene i pamučne tkanine prirodnim bojilom životinjskog podrijetla košenil te je ispitivan utjecaju različitih metala, koncentracije metala, izbora ugušćivača, uvjeta fiksiranja, koncentracije bojila i pH na kvalitetu otiska. Dobiveno je da prirodna košenil bojila nisu postojana na materijalu (vuni i pamuku). U reakciji sa željezom bojilo poprima ljubičasti ton obojenja, a u reakciji s vinskom kiselinom crveni. Pri višim temperaturama fiksiranja, postojanost obojenja je veća.

Abstract (english)

In this final paper under the name: "Textile printing with natural cochenille dye extracted from Dactylopius coccus“ was conducted wool and cotton press with natural dye of animal origin and it was tested by different metals, percentage of metals, selection of thickening agent, requirement of fixation, percentage of thickening agents and pH quality of prints. The results showed that natural coshenille dye is not stable on wool and cotton. In reaction with iron thickening agent will get violet hue and in reaction with tartaric acid it will be red hue. With higher temperatures of printing stability of colors is higher.
