Razvoj in optimiranje novih postopkov barvanja sukancev : zaključno poročilo o rezultatih dela RR faze projekta
Krmek Tručl, Dolores ; Golob, Vera, 1954-2005
Preučevali smo alakalni postopek barvanja PES sukancev. Naročnih izvaja barvanje v križnih navitkih po klasišnem kislem postopku, pri katerem predstavlja pojav oligomerov tehnološke probleme. Za ...barvanje PES sukancev v alkalnem mediju smo izbrali disperzna barvila Serilen ADS firme Yorkshire. Spremljaji smo spremembe pH vrednosti alkalnih kopeli in analizirali njihov vpliv na količino oligomerov. Za računalniško receptiranje smo pripravili podatkovno bazo za 10 barvil v različnih koncentracijah ter optimirali recepture. Preizkušali smo barvne obstojnosti sukancev in ugotovili, da imajo sukanci v črni in temnih barvah slabše obstojnosti na drgnejnje. Optimiranje reduktivne poobdelave črnega sukanca je pokazalo, da je v laboratorijskem merilu najoptimalnejša poobdelava v barvni kopeli takoj po barvanju z minimalnim dodatkom NaOH in Na2S2O4. Pretržna trdnost in razteznost sukancev, barvanih v alkalnem mediju ustreza zahtevam. Pač pa imajo takšni sukanci mehkejši otip in večjo gladkost.
