20.500.12556/DKUM-67813 Ekološke alternative v konvencionalnem postopku barvanja z reaktivnimi barvili Ecological alternatives in the conventional process of dyeing with reactive dyes 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. 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. barvanje reaktivna barvila bombaž vroče pranje ekologija dyeing reactive dye cotton hot-washing ecology true false true Slovenski jezik Angleški jezik Znanstveno delo 2017-08-31 10:13:13 2017-08-31 10:14:30 2022-08-01 14:29:03 2019-07-11 16:32:16 2008 0 0 str. 122-132 št. 4/6 Letn. 51 2008 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 0351-3386 628.33:648.23 763396 12462102 0351-3386 URN:SI:UM:DK:NIGT1Q0M Tekstilec_2008_Sostar-Turk_et_al._Ekoloske_alternative_v_konvencionalnem_postopku_barvanja_z_reaktivnimi_barvili.pdf Tekstilec_2008_Sostar-Turk_et_al._Ekoloske_alternative_v_konvencionalnem_postopku_barvanja_z_reaktivnimi_barvili.pdf 1 7A2D74E854B1B703FF494ACB6CDE9275 2062e443c5c5d7383b764bd698429c295cc5c378dcbbc970ac76134702cd66df 9875b281-7c0e-11eb-bb7a-00155d0001ca 20.500.12556/dkum/909cea66-0770-4f85-84ae-2b19bcd5c29b https://dk.um.si/Dokument.php?lang=slv&id=116545 http://www.tekstilec.si/wp-content/uploads/2008/03/Ekološke-alternative-v-konvencionalnem-postopku-barvanja-z-reaktivnimi-barvili.pdf 1 https://dk.um.si/Dokument.php?lang=slv&id=116544 Fakulteta za strojništvo 0 0 0
