Uticaj dendrimera na bojenje pamuka direktnim bojama
The effect of dendrimer on cotton dyeability with direct dyes
Sažetak
Predtretman pamučne tkanine pomoću poli(propilen-imin)dendrimerom poboljšava jačinu obojenja pomoću C.I. Direct Red 81 i C.I. Direct Blue 78. U ovom radu je proučavan simultana primena ovog dendrimera i direktne boje na pamučnu tkaninu iscrpljivanjem boje i metodom kontinualnog bojenja, pri čemu je bojenje malo poboljšano. Predtretman pamučne tkanine pomoću dendrimera u obliku emulzije se sprovodi metodom fulardovanje-sušenje, nakon čega sledi kontinualno bojenje, značajno povećava jačinu obojenja. Pored toga, dobijen je nivo obojenja, pri čemu nisu uočeni negativni efekti na trajnost osobina boja koje se koriste.
Abstract
Pretreatment of cotton fabric with poly(propylene imine) dendrimer enhanced its colour strength using C.I. Direct Red 81 and C.I. Direct Blue 78. Application of this dendrimer and the direct dye simultaneously on cotton fabric by the exhaust and the continuous dyeing method were studied; slight improvements in the dyeing results were obtained. Pretreatment of the cotton fabric with dendrimer in an emulsion form using the pad-dry method followed by continuous dyeing markedly increased the color strength. In addition, level dyeing was obtained, and no negative effects on the fastness properties of the dyes used were observed.
