The influence of chemical modifications on the chemical composition, sorption properties and volume electrical resistivity of jute fabrics

Abstract

The influence of chemical modifications on chemical composition, sorption properties and volume electrical resistivity of jute fabrics was studied, In order to partially remove hemicelluloses and lignin, modifications with NaOH (1% and 17.5% at RT) and NaClO2 (0.7% at boiling temperature) were applied. Compared to the unmodified, the alkali modified fabrics have lower hemicelluloses content, higher moisture sorption and water retention, while oxidized fabrics have lower lignin content and volume electrical resistivity., but higher water retention. Fabrics modified with 1% NaOH and 0.7% NaClO2 have lower iodine sorption, while for fabrics modified with 17.5% NaOH (30 min), mercerization phenomenon induced higher iodine sorption and higher volume electrical resistivity.
