Abstract

V raziskavi smo v tekstilni tovarni izbrali dve recepturi za barvanje bombažne tkanine z reaktivnimi barvili ter proučili količino in kakovost tekstilnih pomožnih sredstev. Recepture smo modificirali, da bi nevarne kemikalije nadomestili z ekološko prijaznejšimi produkti. KPK vrednosti so pokazale nižjo obremenitev izpiralnih odpadnih voda po barvanju bombaža z modificirano recepturo, kakor tudi višjo biorazgradljivost v primerjavi z izpiralnimi odpadnimi vodami po barvanju bombaža z nemodificirano recepturo, pri čemer je obstojnost barv ostala nespremenjena. Razen tega smo izvedli izboljšanje konvencionalnega izpiranja bombaža, barvanega z reaktivnimi barvili, po modificirani recepturi z uporabo inventivne tehnologije, imenovane "vroče pranje". Pri kontroli izpiralnega procesa se je pokazal prevladujoč vpliv temperature na lastnosti izpiranja barvila. Uporaba procesa "vročega pranja" po reaktivnem barvanju pomeni prihranek vode in časa ter izboljšanje barvnih obstojnosti.

Secondary title:	Ecological alternatives in the conventional process of dyeing with reactive dyes
Secondary abstract:	Two dyeing recipes from a textile factory were studied, focusing on the quantity and quality of the added textile auxiliaries. The recipes were modified to replace hazardous chemicals with environmentally-friendly products. The COD values indicated that wastewaters resulting from the wash-off process of cotton dyed with modified recipes have a lower waste water load and simultaneously a higher degradable capacity, with the same fastness properties as textiles dyed with the original recipes. Additionally, improvement in conventional washing was attained using an innovative rinsing technology, called "hot-washing", after cotton dyeing using a modified recipe. The temperature was a predominant influence on the removal properties of dyestuff and textile auxiliaries. Application of the 'hot-washing' process after reactive dyeing resulted in water and time savings, and an improvement in the fastness properties.
