In this investigation, the influence of alkali modification conditions on the chemical composition, i.e. content of hemicelluloses, moisture sorption and effective relative dielectric permeability of jute woven fabric were studied. In that purpose, jute woven fabric has been alkali modified with NaOH solution (1 %, 5 % and 17.5 %) at room temperature for different periods of time (5 and 30 min). Compared to the unmodified, the alkali modified fabrics have lower hemicelluloses content and higher moisture sorption. With decreasing the content of hemicelluloses, and increasing the moisture sorption, values of effective relative dielectric permeability of investigated jute woven fabrics increased.
U ovom radu je proučavan uticaj alkalnog modifikovanja na hemijski sastav, tj. sadržaj hemiceluloza, sorpciju vlage i na efektivnu relativnu dielektričnu propustljivost tkanina od jute. U tom cilju, tkanina od jute je modifikovana sa NaOH (1%, 5% i 17,5%) na sobnoj temperaturi u toku različitog vremena (5 i 30 min). U odnosu na nemodifikovanu, alkalno modifikovane tkanine imaju niži sadržaj hemiceluloza i povećanu sorpciju vlage. Sa sniženjem sadržaja hemiceluloza, i povećanjem sorpcije vlage, rastu vrednosti efektivne relativne dielektrične propustljivosti ispitivanih tkanina.
