Abstract

Wettability and sorptivity improvements for different textile materials are the major tasks during textile finishing. In order to improve the sorption characteristics of a cellulose fabric, different pre-treatment processes are applied, usually washing, bleaching and mecerisation. Differences in the sorption properties of untreated and pretreated (washed and bleached) regenerated cellulose fibres were obtained using tensiometry and compared with the classical method for determining moisture adsorption. Results show that compared to raw fibres, viscose fibres have the highest moisture and the smallest contact angle whilst modal fibres have the biggest contact angle. Pretreatment increases the sorption abilities and makes the material more accessible to chemicals used in the finishing process. Using the conventional method, it can be confirmed that fibres with the highest moisture have the smallest contact angle (tensiometry).

Secondary abstract: Poboljšanje vlažljivosti i sorptivnosti tekstilnih vlakna najvažnije su zadaće pri završetku izrade tekstila. Kako bi se poboljšale sorpcijske značajke celuloznih vlakana u njihovoj predobradbi rabe se razni postupci, najčešće ispiranje, izbjeljivanje i maceriranje. Razlike u sorpcijskim svojstvima neobrađenih i predobrađenih (ispranih i izbijeljenih) regeneriranih celuloznih vlakana istražene su tenziometrijom i uspoređene s klasičnim postupkom određivanja adsorpcije vlage. U usporedbi sa sirovim vlaknima, viskozna vlakna imaju najmanju vlažnost i najmanji kut kontakta, dok modalna vlakna imaju najveći kut kontakta. Predobradbom se povećavaju sorpcijska svojstva i pristupačnost raznim kemikalijama u završnim postupcima obradbe. Rabljenjem standardnih postupaka potvrdili smo da vlakna najveće vlažnosti posjeduju najmanji kontaktni kut, što je dokazano tenziometrijom.
