Abstract
V diplomskem delu je bil proučevan vpliv zaščitne apreture na barvo tekstilij, pobarvanih z naravnim barvilom. Z naravnim barvilom kurkume (kurkumin) je bila pobarvana stoodstotno bombažna tkanina. Kot zaščitna apretura je bil izbran vodo- in oljeodbojni anorganski-organski hibridni prekurzor fluoroalkil funkcionalnega siloksana (FAS), ki je bil na bombažno tkanino nanesen po barvanju ali med barvanjem. Na vzorcih so bile opravljene analize površine, kot so oljeodbojnost, merjenje barve na refleksijskem spektrofotometru pred petkratnim in desetkratnim pranjem in po njem, ocenjevanje barvnih obstojnosti po sivi in modri skali po testih obstojnosti pri drgnjenju, svetlobi in vročem likanju. Rezultati so pokazali, da je za barvo in barvne obstojnosti pomemben vrstni red nanosa FAS-apreture. Apretura, nanesena med barvanjem, zniža vrednosti K/S, zviša pralno obstojnost, obstojnost pri svetlobi in drgnjenju, zniža pa obstojnost pri vročem likanju.

Title:Influence of oil- and water-reppelent finish on colour of cotton dyed with curcumin
Abstract:
This diploma thesis studies the impact of protective finishing on the colour of textile, dyed with natural colours. A 100% cotton textile was dyed with a natural turmeric (curcuma) dye. Water and oil repellent inorganic-organic hybrid precursor fluoroalkyl-functional siloxane (FAS) was selected as protective finishing agent, and was applied to the cotton fabric surface after or during dyeing. Different surface analyses were carried out on the samples, such as oil repellency, colour measurements on the reflectance spectrophotometer before and after fifth and tenth laundering, colour fastness to rubbing, light and hot ironing using the grey and blue scales. The results showed that the order of application of FAS apreture is important for the colour and colour fastness. FAS applied during dyeing lowers the K/S value, increases its wash resistance, resistance to light and rubbing and decreases resistance to hot ironing.

Keywords:cotton, turmeric, dyeing, water and oil repellent finishing, colour fastness
