The jute woven fabric was treated with sodium hydroxide at room
temperature for 5, 30 and 45 min in order to obtain jute fabric with different
hemicelluloses content and to study their influence on the dielectric loss tangent. After
the alkali treatments, as the result of the hemicelluloses removal, the moisture sorption
of the jute fabrics increased. The X-ray diffraction analysis shows that the jute fabrics
with lower hemicelluloses content have a lower crystallinity index, which slightly
increased after the intensive hemicelluloses removal. These results are in a good
agreement with the results obtained for dielectric loss tangent measured at 30% and
80% relative air humidity.
Tkanina od jute je tretirana sa natrijum-hidroksidom na sobnoj
temperaturi u toku 5, 30 i 45 min u cilju dobijanja tkanina od jute sa različitim
sadržajem hemiceluloza i proučavanja njihovog uticaja na tangens dielektričnih
gubitaka. Nakon alkalnih tretmana, kao rezultat uklanjanja hemiceluloza, sorpcija vlage
se povećava. Analiza rezultata dobijena rendgenskom difrakcijom pokazuje da tkanine
sa manjim sadržajem hemiceluloza imaju manji indeks kristalnosti, koji se malo
povećava nakon intenzivnog uklanjanja hemiceluloza. Dobijeni rezultati su u saglasnosti
sa rezultatima dobijenim za tangens dielektričnih gubitaka merenim pri 30% i 80%
relativne vlažnosti.
