Ekološke alternative v konvencionalnem postopku barvanja z reaktivnimi barvili
Sonja Šostar-Turk, Reinhold Schneider, Irena Petrinić, Rebeka Fijan, 2008, original scientific article

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.

Good quality printing with reactive dyes using guar gum and biodegradable additives
Reinhold Schneider, Sonja Šostar-Turk, 2003, original scientific article

Abstract: In printing with reactive dyes sodium alginates or synthetic thickeners are typically used as thickening agents to prevent unacceptable fabric handle. A new reactive printing process for reactive dyes on cellulosic textiles has been developed using natural thickening agents and environmental-friendly additives. Printing trials with guar gums have shown that the use of differentadditives can prevent fabric stiffness. These additives have no significant influence on rheology and colour strength but contributed to soft fabric handle even when guar gums were used as thickening agent. The use of additives and guar gum provide good quality prints with reduced wastewater pollution.
